Thank you for this video. l just changed the oil on my Duke 390 and had a part left over in the kit. After watching your video l learned that it was an oil strainer that fits in the drain plug hole, which l had no idea about. I drained the new oil out, fitted the new part, and was able to save the oil and put it back in.
thanks a lot! I followed exactly what you showed and changed oil smoothly. You know what, i barely knew anything about machine before I watched you video. you just helped that much.

Hi Jageth, apologies for the very late reply - TH-cam can be weird about showing replies to Creators and I've only just seen this :( Glad the videos are useful and by the sound of it keep up the good work! Videos are one thing but you still need to implement the work yourself! Skäl David
Great video, thanks so much for sharing! One note about the bolts on the oil filter cover: the bolts may not be 12 NM on all models. On my 390, they are 8 NM. If you try to torque them to 12 NM, you will either snap the bolts or strip the threads. Make sure you read the manual for your model!
@@AaronCohn84 Interesting. The parts diagram shows that the 2016 and 2017 use the same bolts yet in 2017 KTM have increased the torque to 12NM - which suggests that they won't snap or cause other damage regardless of whether you have a gen 1 or a gen 2.
@@MotoMirius I attempted to use 12 NM after watching your video, and the result was 1 snapped bolt and 1 nearly destroyed. I was lucky to extract the broken bolt without much trouble. I got some new bolts from the store, which were made of higher grade metal, and attempted to screw those in at 12 NM. The result was stripped threads. In case there’s any doubt that my torque wrench is operating correctly, I successfully torqued the drain bolts to 15 and 12 without any issue, and it was fine when I had it set to a lower torque, like 5 NM. So pretty much it’s just my brain that was not operating correctly 😖
@@AaronCohn84 12Nm is what KTM recommend, and this is why I recommend it. My personal opinion is that the Indian sourced hardware used on these bikes is sometimes sub-standard. It also assumes that your bolts have never in the last five years been overtorqued or the case threads otherwise strained or poorly tapped at the factory, all or any of which could create the result that you've experienced. I appreciate that you have had a poor experience, but is the reality of working on vehicles even when you do everything right. From your comments, KTM appear to have increased the torque spec on these bolts and that is unlikely to be a random or accidental change but probably the result of dealer feedback. If you check the online torque ratings for a 6mm socket head bolt, 12Nm is fairly common - but does assume that an appropriate grade of steel has been used.
Great video, keep it up! I'm still in my warranty period so having my KTM serviced by the official dealers (which is spenny). Will be using your vids once warranty is up! Good watch still
As always a fantastic video! I followed your instructions step by step today and successfully changed my oil, filters and screens without hitch. Although, I couldn’t find a magnet anywhere (I can confirm fridge magnets are not strong enough lol), so I gently hammered a small tack in to the centre of the old oil filter enabling me to pull it out. You have given me the confidence to tackle many jobs on the bike. I recently swapped out the decat pipe for the arrow pipe and kept the pre silencer (as recommended), it sounds absolutely awesome….plenty loud enough. One quick question, what adjustable torque wrench do you use? I need to invest in one so any advice would be most appreciated. Thanks.
Great improvisation! I think KTM recommend circlip pliers for the job, so it really depends what you have to hand. I have several different torque wrenches, all of different makes - one won't work for everything on the bike - the one I used on this is an old fashioned one from Britool. I don't have a recommendation for brand, but it needs to be a decent make with a good reputation, and not a fake or copy.
Previously i followed orange blooded motomaniac. because of language barrier i prefer yours. you teach everything in details.Thanks a lot sir. oh btw i see there is leakage from your shaft there 3:40
Thanks. Much appreciated. I would expect so yes. There are some differences in the engines but not as far as I’m aware with regards the oil. Skäl. David
Indeed, and when you do so is the subject of much debate. In practice I can't say I've noticed any difference, I always do it after removing the drain plug and with a multiple drain and filter setup like this there is plenty of air getting into the system.
Hi mate New to the bike world and just bought a 2021 duke 125 and reached 1000 kms.What oil will i use on the change.Loving your videos mate thanks alot..
Thanks. KTM recommends 15w50, sometimes I use 10w40. KTM recommends Motorex - because that is their oil partner. Most oil companies have a website, and often have an oil finder that recommends the right oil of theirs for your bike - Motorex for example has one and gives a couple of alternative oils. Don't use car oil, you need one that is designed for a wet clutch, oil spec should be at least JAO T903 MA2 - it will be in the description but most bike oils from the major manufacturers will meet this.
Hi thanks for all your KTM videos they have been an integral part of my Duke ownership,can you clarify when checking the oil level window should the bike be on its side stand or upright?
Great video, will be very helpful when the time comes to service my Duke 125. Looking at 3:15 - would you suggest to get cover protectors for the clutch and gearbox covers ? KTM sells some orange aluminum protectors for that. I see that your Duke was scratched quite a bit in that place. Cheers 🙂
Thanks. I have a couple of videos on engine protection - including a general crash protection one - th-cam.com/video/KE5gPkMhCqY/w-d-xo.html. I prefer the cage for engine protection, but currently I have the KTM Powerparts sliders you mention fitted. They are simple to fit - and again there is a video. I think it's worth doing.
Excellent content in clip, much appreciated sir. Drained my oil duke 390 2016 yesterday, noticed oil has water contamination. From your experience have you replaced the seals behind the water pump impellor, if you have carried out this work can you access both pump shaft seals after the impellor has been removed? Thank you for advice Mr Moto Mirius.
Thanks. Yes, very likely the pump seals. I haven't done it but yes you can access and remove both pump seals from the outside of the engine and without removing it from the frame. Good luck!
@@MotoMirius thanks for your reply, very helpful. Your knowledge on motorcycles is very impressive. You make it look straightforward tackling work on bike. Thanks from London, England.
hope you could also show us how to change brake pads, front and rear, and which brand and model suits. newfren and brembo are more accessible for me . so appreciate if you could advice on these 2. thanks a million.
Buy pads from a reputable maker. Here I buy EBC. There is little special or technical about pads - so be careful to avoid paying just for a brand name, but also don't buy cheap or fake because these can be badly made. Stock pads on the front are sintered on the gen 2 bikes - no point in changing them, you won't get better braking on the road from Brembo pads. I use sintered pads back and front - they will wear the disk out faster but they brake better - but don't go overboard on the back unless you race - KTM didn't fit sintered on the back, because you don't need them unless you trail brake a lot. Skäl David
Great video - as always! I find it strange that KTM wants the oil level to be checked with the engine hot... When my 390 is at operating temp. and the bike is upright the oil level is between the min. and max. mark on the sight glass as per KTM instruction... however when I check when the bike is cold I do not actually see the oil in the sight glass.... Not a good practice as one now assumes that the bike has enough oil - and that is as you start a journey. I spoke to the dealer as I was told not to add any oil....
Yep. That’s how it is. If you bear in mind that KTM make dirt bikes it becomes much more normal because a lot of dirt bikes run dry sumps - which you have to check when at operating temperature. I very much regard the 390 as a dirt bike in design and now I have decatted it, it sounds like one too! I must admit though, the oil checking procedure is one I dislike and I never liked it with any dry dump bike either. Skäl. David
Correct... even KTM dealers complain about this... it is stupid! No one should ride a bike if you can not see oil in the sight glass when you start your journey.
I agree but... this is normal on many bikes. It’s necessary to learn to check the oil at the end of the ride instead of at the start. Much like its better to oil the chain at the end instead of the beginning of the ride. Skäl. David
@@MotoMirius .... with all due respect, I think a lot of damage can be done by riding with too little oil - so I always make sure the oil level is correct before I ride. Better be safe than soŕry!
Awesome. Have 4 litres of Motul 300V Factory Line 10W40 4T arriving any day now. Just ordering the Filter service kit which I had NO idea existed until I watched your video so thank you for the heads up. Quick question - how often to chain the oil (miles or km) and how often to change the filters and screens?
Hey David. Great to see you pushing ahead yourself. KTM recommend oil changes every 7500km or once a year, whichever happens first and to clean the screens at the same time - change if damaged or the seals are going. Personally I tend to change twice a year and if you lay the bike up for say winter then change the oil before you do. Never hurts to play safe and change the oil too often! Good luck. Skäl David
I have the KTM Duke 125 it’s it the same to change the oil as you have shown in the video if so Big thanks it was very helpful for me as I am now rider Thanks Larry
Hi Larry, yes the process is the same, the 125 takes less oil because it is a smaller engine. I believe it is 1.2l for oil change and 1.5l with filter, but adjust as needed using the sight glass. Good luck!
Oil capacity is 1.7l but there will always be residual oil in the system, always check the level instead - so if you add 1.7l you may overfill. Add oil, bring the bike to temperature and check level - it is easier to add a small amount of oil than to remove a small amount of oil
Thanks. Engine case damage when the previous owner wrote the bike off. KTM crash bars or case sliders are highly recommended. I wouldn’t recommend any of the aftermarket alternatives aside from the Chinese KTM copies - so long as you can live with colour not matching. Stunt cages are also fine. The current slide damage to the crash bars happened when I high sided it 😂. Skäl. David
I came across pn your vid since im planning to get a 390 too. Hope you don't mind me asking you about the traces of oil @3:30 near the shift lever where is it coming from? Lastly @12:19 since there is a film of oil on your finger when you touched the cover or the oil filter what have you done? Would appreciate your feedback Thanks!
If your bike doesn’t have traces of oil around the shift lever area then you probably aren’t putting enough oil on the chain. You will get oil on the filter cover if you spill any oil when filling - especially likely if you have crash bars getting in the way. Skäl. David
Hi there, love the videos. I see they sell 4 liter bottles of Motorex 15/50. If the 390 Duke needs 2 liters what is the best way to measure this? Is it just pouring half of the 4 liter in? I just want to be precise and sometimes it's hard to see inside the Motorex bottle to see if it's half way. Thanks.
Thank you. KTM don’t recommend measuring like that, and it’s always difficult to be precise with the bottles. Fill to the correct level in the sight glass. Then bring the engine up to temperature and then top up to the correct level. Skäl. David
thankes for the video! i have his brother the new rc390 2023. i hope you could answer my question.. my bike leans to the right while riding and i feel it when i released my hands off while riding and the bike goes right.. my last bike rc200 has go straight while i did it. but i didnt had an Exhaust pipe on it and in the 390 i has an exhaust pipe so i thought its hart the balance of the bike because its also in the right side.. what do you think? does you does your bike also leans a little to the right?
Thanks. Bike should not lean left or right, exhaust will not affect it - rotational mass of wheels keeps it upright. Most likely the front wheel is not properly aligned in the forks.
G'day David, Just completed a service on my Duke 390, All has gone well however I am concerned with the amount of oil I have put in and what the level is telling me vs what the service manual says. I followed the instructions completely and replaced both oil screens, oil plugs, all o-rings and drained the oil completely. So far I have added 1.8L of oil to the duke and run the bike to operating temperature, the sight glass, however, reads barely above the minimum mark, I believe this is due to the fact I have replaced both oil screens and the filter, all 3 will absorb some of the oil to a degree. Your thoughts as always would be greatly appreciated. Rohan.
Hi Rohan. The service manual does not specify the total volume of oil to be added. It’s process is: change filters, add 1.7l, bring up to operating temp and stand the bike upright. Then add oil until the correct level. It sounds like you just need to add more oil - with the engine at operating temperature. Skäl. David
@@MotoMirius Thanks David, Topped up today to a total of 1.9L level now reads perfectly when the bike is hot. Time to bleed the brakes and change the coolant. Rohan
Great video just done an oil change on my duke 390 2014 bought it a few months ago and noticed when i drained the oil there are black specs in the oil im guessing carbon deposits? Has anyone else had this problem? Other than that mine is still running flawless but im hoping my engine doesn't blow lol
Filters should be pulled every oil change. You can wash them off - if the mesh is damaged or looks like its starting to clog then change them. There is no harm in changing them every oil change if you want.
Rock oil has a good reputation. I use both systhesis and guardian in my bikes. I've also used one of their more off road spec oils for this bike. If you look at their website (and the same is true of most oil companies) they have a bike finder which will recommend oil for your bike and you can then choose which suits your use and budget. The more you blat the bike, the more you should spend on oil. If you just cruise around town trying to get the maximum mpg then guardian is fine.
I always add oil to bring it up to the right level. Some people like to measure it and always put the same amount in, and that works for them, I just add oil until the level is right.
I don't have the oil capacity for the125, it will be a little less than the 390, but the grade is the same as for the 125 (and pretty much any other bike). Just watch the sight glass as you fill, you don't need to measure it.
Hello sir. What size hex key allen wrench tool and nut drivers did you use? I have seen countless vids, but no one discusses the size tools. I need to buy tools for the Philippines. Planning to buy the Duke 390 when I arrive in June. This information would be so helpful. Thank you kindly.
Hi. I have listed tools before but it is a pointless exercise as a basic tool kit will cover everything you need. Basic tools are an investment - I am still using the same spanner and socket set that I bought thirty years ago - once you have bought them, you will use them again and again. Skäl David
@@MotoMirius Thank you Moto. Yes, I have been wrench turning for 30+ years. For those others just looking to buy tools to change their oil - you will need allen wrenches and socket set to do this job. Specifically, 3.5mm and 10mm for removing the cowling. The drain bolts will take 8mm, 13mm, and 18mm. KTM, from what I can tell, are all metric.
So, what I took from this is that you only replace the actual oil filter. You don’t replace the screens. At what point or kilometers will you have to replace the side and bottom screen filter(s)?
Hi Brian. First service is 1,000km or 620 miles. You could change the oil before that but it will take that long to properly flush the oil channels out of all the swarf into the screens that they don't bother to flush out at manufacture. Skäl David
Both work - so long as you buy the right ones. Full synthetic supposedly can be changed less often but is more expensive. If you hammer the bike a lot then synthetic can be a good choice, but very much swings and roundabouts - nothing wrong with either, more important to change it to be honest.
That’s where torque wrenches get expensive. You need at least two if not three to cover all the range you need. In practice for the low range just wrist tight with a short wrench is fine. Skäl. David
No separate oil. Very few modern bikes have a different gearbox oil - those that do are mostly US bikes such as Harley, or old copies still being made in say India of old British bikes - all of which are running very old engine designs
It depends on the year. On the later bikes the strainers appear to be the same parts but on earlier bikes only 390 and 250 appear to share both the same strainers.
I blow them off with air, but you can use any bike friendly solvent, if you don't have air. Some use brake cleaner but you aren't trying to degrease them, just remove any particles from the screen.
The screen can get clogged so it's best that both drain plugs are useable. On an older bike the risk of the screen clogging is lower so you might get away with it. It's impossible to quantify the risk - it might never be an issue - but if you ever get an oil pressure warning on the dash then you need to get it fixed.
Hello! It will be fine if you pour this oil into the 2016 KTM Duke 125. Motorex Top Speed 4T 15W-50. And now we don't have Formula 4T. Blessings to you.
If you are in a hotter country and that is motorcycle oil not car oil then it should be fine. 20w50 would be too thick for colder countries which is why most motorcyle oil is 15w. 20W50 is used in some older style motorcycle engines such as Harley where the oil passages are bigger.
Most people don't have access to a torque wrench. Do it up lightly so it touches and then just a little more. If it leaks nip it up a bit more - I recommend not putting the bottom plastic on for a few days so you can check it. If you overdo it you'll damage the alloy plug and need to buy another (not that this has ever happened to me...) Skäl David
I use an oil made by a UK oil company. You should use an oil which meets the JASO T903 MA2 standards. Most oil manufacturers will recommend an oil for your bike on their website. KTM recommend semi synthetic and since they have a sponsorship with Motorex recommend Motorex Formula 4T. If you are within the warranty period on your bike then I would recommend sticking with the recommended products to avoid any risk of challenges. I'm currently using Rock Oil Synthesis XRP Off Road 10w50. Skäl David
Oil weight is mostly temperature related. Here in the UK 15/40 is commonly used but if you ride somewhere hotter this could be a mistake because the oil may not offer protection at startup.
It will take two litres of oil if you have changed the oil filter. Make sure the bike is properly upright and at the right temperature - if the bike leans away from you the oil will not be visible. Skäl David
You have to run the bike before starting. To correctly read the oil level you must bring it up to operating temperature which you can read on the dashboard.
CAREFUL! - The Oil Filter cover bolts are NOT 12Nm, they are 8Nm, got a sheared bolt due to that error. The front Oil Screen is 12NM, the side one is 15Nm.
@@Iam-ix4he Yes and no. The manual, in the section that describes how to change the oil clearly states it is 12. In the general torque sheet it lists it as 8. 12 is a normal level of torque for an M6 bolt. But if the threads are not clean on bolt and engine case then the bolt can bind and shear. Also sub standard bolts can be an issue.
KTM list the oil change interval at 7,500km or once a year - depending which happens first. Many riders prefer to change twice a year, and if you lay up the bike for a period - for example over winter, then change the oil before you do so.
Dear Sir David, May i ask a question? I had a problem. Could you give a suggestion? I have a KTM Duke 390(2017). Last day i started it and everything was normal at start-up. I rode it about 2-3 km then it gave a "Low Oil Pressure" warning. I checked the oil level, it was a little bit below the normal level. I changed oil and oil filter. Warning disapared. i didn't used 2 days but today i rode it again. At begining everything was normal then again i got same warning after 3-4 km. What could be the problem? Please help me? Kind regards
Was the oil normal when you changed it? If it wasn't then there can be a failure of the seal on the water pump. Sometimes the oil pressure switch can be faulty and gives this error. Otherwise you should get a KTM dealer to check the oil pressure. Good luck
@@MotoMirius Actually KTM dealer is a bit far away to me so, i got some helps for chaning oil and oil filter from a local mechanic. I told him "low oil pressure warnning". Probably he didn't understand me. He mixed it with service warning. I will call KTM dealer as soon as possibly. I will tell them about your advides. Thank you so much.
@@erhantiryaki If you don't have a local KTM dealer then find a mechanic who has the tools to check the oil pressure. This error is often a sensor failure - but oil pumps also fail so you really shouldn't run the engine until you've identified the fault.
Whilst you can do that, KTM do not agree with you. The process I have shown is as described by KTM. Filing filters with oil before fitting is not usual with this design of filter, and with many filter fittings not even possible. Skäl. David
Yes if u fill the oil fiter with oil it will be good for the engine,but in this case it doesn't matter because The filter housing holds very minimal amount of oil and second it is difficult to do that and don't worth and you can't fill it to the full anyways so it doesn't matter
Sir i have ridden my Duke390 about 4500km since last service it has taken about 300ml of engine oil topup overall, there is no leaks at all no smoke from exhaust still the level goes down. Is it normal for ktm? Engine oil motul7100 10W50
If there are no leaks and no smoke from the exhaust then the level should not go down - but some loss is normal. You do not mention how long ago your service was.
Do you know how to remover the sight glass. Mine has white residue on it. I want to take it out to clean it. I'm wondering if I just remover the circlip and it should pop out but I am not sure.
White residue is normal during cold weather and should clear up once the oil gets hot and the water reabsorbs. It should come out but I've not tested it myself - I plan on checking the clutch at some point in the not so distant future so I should find out then.
@@MotoMirius thanks for the reply. It's been like it since I bought the bike. Last year. I have done a couple of oil changes but it has never cleared. I am due to change the oil again over Christmas so may investigate myself.
Daniel Mak typically it will be about six months Daniel. I may extend that on a bike I don’t use a lot but it’s important not to let used oil sit in an engine for too long.

When the dealer changes the oil, they are supposed to also test the oil pressure to ensure that oil pump is working properly. You also have to ensure that the oil level is correct - this is a dry sump type engine as far as checking oil level is concerned. If you check the oil level with the engine cold then you will not have enough oil in the engine - and it will get damaged. That you are getting the same problem suggests that the oil level is being checked with the engine cold. If this is a KTM dealer then make sure that they have tested the oil pressure. It might be time to find a more reputable garage who know what they are doing.
@@MotoMirius im kind of stuck now cant ride it closest KTM dealer is over 30 miles away... the engine oil lvl is fine i know how to check that ive left the engine running for a good 10 mins and checked the oil lvl b4 this happend just over a week ago as i had a long trip to make now i have this problem (low oil pressure) whats the best thing i can do ? im pretty sure i can fix it myself i just need to know the problem.. could it be oil pump?
@@404hotshot low oil pressure where the level is correct has two most common issues - blockages in the oil galleries - most often clogged filter or screens, or a faulty pump. If you changed the oil and filter then the most likely culprit is the pump. Oil pressure sensor is also a possible culprit so you could swap that out as well - testing is possible but mostly tells you if it works, not if it works at the right pressure.
@@MotoMirius ok ill replace all 3 i hope the oil pump is not to hard to get to ill buy a oil pressure test kit as well and go from there than for your help
Hi Daniel. KTM spec is 15w50 but here in the UK it rarely gets hot enough to justify putting in an oil with that heat rating but it does get cold enough that I’m comfortable enough dropping below to 10. Rock Oil who are a UK oil manufacturer recommend 10w30. Skäl. David
Daniel Mak hot would be tropics, places like India. I have a video on oil choice that might explain my views on it. As I said in the video, using the recommended oil by Motorex is what I recommend. But the right oil for say India isn’t the right oil for Alaska, so there is room for deviating from recommendations - at your own risk of course.

Great video, thanks so much for sharing! One note about the bolts on the oil filter cover: the bolts may not be 12 NM on all models. On my 390, they are 8 NM. If you try to torque them to 12 NM, you will either snap the bolts or strip the threads. Make sure you read the manual for your model!

From your comments, KTM appear to have increased the torque spec on these bolts and that is unlikely to be a random or accidental change but probably the result of dealer feedback. If you check the online torque ratings for a 6mm socket head bolt, 12Nm is fairly common - but does assume that an appropriate grade of steel has been used.
Please continue the Duke 200/250/390 series! Big fan 🪭
Thanks, more videos are planned soon - I need to create some space in my shed so I can film again

Great video, keep it up! I'm still in my warranty period so having my KTM serviced by the official dealers (which is spenny). Will be using your vids once warranty is up! Good watch still
Thanks for that. More servicing videos will go up as they come around. Skäl. David
As always a fantastic video! I followed your instructions step by step today and successfully changed my oil, filters and screens without hitch. Although, I couldn’t find a magnet anywhere (I can confirm fridge magnets are not strong enough lol), so I gently hammered a small tack in to the centre of the old oil filter enabling me to pull it out.
You have given me the confidence to tackle many jobs on the bike. I recently swapped out the decat pipe for the arrow pipe and kept the pre silencer (as recommended), it sounds absolutely awesome….plenty loud enough.
One quick question, what adjustable torque wrench do you use?
I need to invest in one so any advice would be most appreciated. Thanks.
Great improvisation! I think KTM recommend circlip pliers for the job, so it really depends what you have to hand. I have several different torque wrenches, all of different makes - one won't work for everything on the bike - the one I used on this is an old fashioned one from Britool. I don't have a recommendation for brand, but it needs to be a decent make with a good reputation, and not a fake or copy.
@@MotoMirius I use a normal nose plier for the job. Barely takes a second. Really easy.
Previously i followed orange blooded motomaniac. because of language barrier i prefer yours. you teach everything in details.Thanks a lot sir. oh btw i see there is leakage from your shaft there 3:40
Thanks, much appreciated. Not leakage - chain oil.
Great vid good instructions and easy to follow . Is the 125 duke the same for the filters ?
Thanks. Much appreciated. I would expect so yes. There are some differences in the engines but not as far as I’m aware with regards the oil. Skäl. David
Good idea to remove the filler cap when draining the oil too.
Indeed, and when you do so is the subject of much debate. In practice I can't say I've noticed any difference, I always do it after removing the drain plug and with a multiple drain and filter setup like this there is plenty of air getting into the system.
Hi mate
New to the bike world and just bought a 2021 duke 125 and reached 1000 kms.What oil will i use on the change.Loving your videos mate thanks alot..
Thanks. KTM recommends 15w50, sometimes I use 10w40. KTM recommends Motorex - because that is their oil partner. Most oil companies have a website, and often have an oil finder that recommends the right oil of theirs for your bike - Motorex for example has one and gives a couple of alternative oils. Don't use car oil, you need one that is designed for a wet clutch, oil spec should be at least JAO T903 MA2 - it will be in the description but most bike oils from the major manufacturers will meet this.
Nice video! Is the front spoiler needed for protection or is it just for looks?
Thanks. It’s a road bike so it’s mostly for looks though it does help a bit with protection from stuff thrown up from the road. Skäl. David
Hi thanks for all your KTM videos they have been an integral part of my Duke ownership,can you clarify when checking the oil level window should the bike be on its side stand or upright?
Thanks. The bike must be upright with the oil at operating temperature.
Great video, will be very helpful when the time comes to service my Duke 125. Looking at 3:15 - would you suggest to get cover protectors for the clutch and gearbox covers ? KTM sells some orange aluminum protectors for that. I see that your Duke was scratched quite a bit in that place. Cheers 🙂
Thanks. I have a couple of videos on engine protection - including a general crash protection one - th-cam.com/video/KE5gPkMhCqY/w-d-xo.html. I prefer the cage for engine protection, but currently I have the KTM Powerparts sliders you mention fitted. They are simple to fit - and again there is a video. I think it's worth doing.
@@MotoMirius Thanks !
Excellent content in clip, much appreciated sir.
Drained my oil duke 390 2016 yesterday, noticed oil has water contamination.
From your experience have you replaced the seals behind the water pump impellor, if you have carried out this work can you access both pump shaft seals after the impellor has been removed?
Thank you for advice Mr Moto Mirius.
Thanks. Yes, very likely the pump seals. I haven't done it but yes you can access and remove both pump seals from the outside of the engine and without removing it from the frame. Good luck!
@@MotoMirius thanks for your reply, very helpful.
Your knowledge on motorcycles is very impressive.
You make it look straightforward tackling work on bike.
Thanks from London, England.
You mentioned Oilfilter Service Kit. It comes with a screen.
Yes it does, as shown in the video. But if the current one is clean and in good condition, you don't necessarily need to change it.
hope you could also show us how to change brake pads, front and rear, and which brand and model suits. newfren and brembo are more accessible for me . so appreciate if you could advice on these 2. thanks a million.
Buy pads from a reputable maker. Here I buy EBC. There is little special or technical about pads - so be careful to avoid paying just for a brand name, but also don't buy cheap or fake because these can be badly made. Stock pads on the front are sintered on the gen 2 bikes - no point in changing them, you won't get better braking on the road from Brembo pads. I use sintered pads back and front - they will wear the disk out faster but they brake better - but don't go overboard on the back unless you race - KTM didn't fit sintered on the back, because you don't need them unless you trail brake a lot. Skäl David
Great video - as always! I find it strange that KTM wants the oil level to be checked with the engine hot... When my 390 is at operating temp. and the bike is upright the oil level is between the min. and max. mark on the sight glass as per KTM instruction... however when I check when the bike is cold I do not actually see the oil in the sight glass.... Not a good practice as one now assumes that the bike has enough oil - and that is as you start a journey. I spoke to the dealer as I was told not to add any oil....
Yep. That’s how it is. If you bear in mind that KTM make dirt bikes it becomes much more normal because a lot of dirt bikes run dry sumps - which you have to check when at operating temperature.
I very much regard the 390 as a dirt bike in design and now I have decatted it, it sounds like one too! I must admit though, the oil checking procedure is one I dislike and I never liked it with any dry dump bike either. Skäl. David
The manual indicates to check the oil levels after you use the bike, not when it is cold.
Correct... even KTM dealers complain about this... it is stupid! No one should ride a bike if you can not see oil in the sight glass when you start your journey.
I agree but... this is normal on many bikes. It’s necessary to learn to check the oil at the end of the ride instead of at the start. Much like its better to oil the chain at the end instead of the beginning of the ride. Skäl. David
@@MotoMirius .... with all due respect, I think a lot of damage can be done by riding with too little oil - so I always make sure the oil level is correct before I ride. Better be safe than soŕry!
Awesome. Have 4 litres of Motul 300V Factory Line 10W40 4T arriving any day now. Just ordering the Filter service kit which I had NO idea existed until I watched your video so thank you for the heads up. Quick question - how often to chain the oil (miles or km) and how often to change the filters and screens?
'change' the oil, not 'chain'. Doh!
Hmmmm thinking I might change it for the 15W50 for Australia. The winters aren't *that* cold.
Hey David. Great to see you pushing ahead yourself. KTM recommend oil changes every 7500km or once a year, whichever happens first and to clean the screens at the same time - change if damaged or the seals are going. Personally I tend to change twice a year and if you lay the bike up for say winter then change the oil before you do. Never hurts to play safe and change the oil too often! Good luck. Skäl David
I'm always in favour of tweaking the oil to your local climate.
I have the KTM Duke 125 it’s it the same to change the oil as you have shown in the video if so Big thanks it was very helpful for me as I am now rider Thanks Larry
Hi Larry, yes the process is the same, the 125 takes less oil because it is a smaller engine. I believe it is 1.2l for oil change and 1.5l with filter, but adjust as needed using the sight glass. Good luck!
Love your videos, very educational. Have you ever noticed minor leaks on your duke ?
Thanks. No, no modern bikes should have minor leaks.
Thank you so much !!! Great vid!!! Love my Duke!!!
Thank. Love mine too! Skäl David
Hi there, thanks for this useful video 🙏
To double check, the oil capacity on duke 390 2017-2019 is 1,5l or 1,7l?
Oil capacity is 1.7l but there will always be residual oil in the system, always check the level instead - so if you add 1.7l you may overfill. Add oil, bring the bike to temperature and check level - it is easier to add a small amount of oil than to remove a small amount of oil
Thank you for this video. Very useful from a Duke 125 rider👍
Glad you liked it and good luck with the change.
@@MotoMirius Thank you😊
Cheers for the video mate, really useful. Did that damage on your engine case happen before you had the crash bars, or with them installed?
Thanks. Engine case damage when the previous owner wrote the bike off. KTM crash bars or case sliders are highly recommended. I wouldn’t recommend any of the aftermarket alternatives aside from the Chinese KTM copies - so long as you can live with colour not matching. Stunt cages are also fine. The current slide damage to the crash bars happened when I high sided it 😂. Skäl. David
@@MotoMirius Cheers David! Very helpful. How much oil did you put in before warming the engine up? 1.5 litres?
@@pu11y From memory yes - 1.5 to 1.7 litres.
Can you do a video on throttle cable replacement
Do you have a gen 1? 2017 on is ride by wire so no cables.
I came across pn your vid since im planning to get a 390 too.
Hope you don't mind me asking you about the traces of oil @3:30 near the shift lever where is it coming from?
Lastly @12:19 since there is a film of oil on your finger when you touched the cover or the oil filter what have you done?
Would appreciate your feedback Thanks!
If your bike doesn’t have traces of oil around the shift lever area then you probably aren’t putting enough oil on the chain. You will get oil on the filter cover if you spill any oil when filling - especially likely if you have crash bars getting in the way. Skäl. David
Great video. Congrats
Thanks. Much appreciated. Skäl. David
Hi there, love the videos. I see they sell 4 liter bottles of Motorex 15/50. If the 390 Duke needs 2 liters what is the best way to measure this? Is it just pouring half of the 4 liter in? I just want to be precise and sometimes it's hard to see inside the Motorex bottle to see if it's half way. Thanks.
Thank you. KTM don’t recommend measuring like that, and it’s always difficult to be precise with the bottles. Fill to the correct level in the sight glass. Then bring the engine up to temperature and then top up to the correct level. Skäl. David
@@MotoMirius Thank you
i saw a local mechanic put a tissue or old rag in the drain pan, it cushions the initial splash n less mess.
That works. But a proper pan keeps the splash inside the tray (unless you miss of course!)
thankes for the video! i have his brother the new rc390 2023. i hope you could answer my question.. my bike leans to the right while riding and i feel it when i released my hands off while riding and the bike goes right.. my last bike rc200 has go straight while i did it. but i didnt had an Exhaust pipe on it and in the 390 i has an exhaust pipe so i thought its hart the balance of the bike because its also in the right side.. what do you think? does you does your bike also leans a little to the right?
Thanks. Bike should not lean left or right, exhaust will not affect it - rotational mass of wheels keeps it upright. Most likely the front wheel is not properly aligned in the forks.
Great videos man I own a ktm duke 2018 125cc so the videos help me out a lot thanks 🙏🏻 😊

7:23 cool trick with magnet
in my case the magnet was absent and i had to drill with a screw
A screw will do the job, or circlip pliers if you have them to fit! Good improvisation!
G'day David,
Just completed a service on my Duke 390, All has gone well however I am concerned with the amount of oil I have put in and what the level is telling me vs what the service manual says.
I followed the instructions completely and replaced both oil screens, oil plugs, all o-rings and drained the oil completely.
So far I have added 1.8L of oil to the duke and run the bike to operating temperature, the sight glass, however, reads barely above the minimum mark, I believe this is due to the fact I have replaced both oil screens and the filter, all 3 will absorb some of the oil to a degree.
Your thoughts as always would be greatly appreciated.
Rohan.
Hi Rohan. The service manual does not specify the total volume of oil to be added. It’s process is: change filters, add 1.7l, bring up to operating temp and stand the bike upright. Then add oil until the correct level. It sounds like you just need to add more oil - with the engine at operating temperature. Skäl. David
@@MotoMirius Thanks David,
Topped up today to a total of 1.9L level now reads perfectly when the bike is hot.
Time to bleed the brakes and change the coolant.
Rohan
Sounds like a good job there. I suspect KTM don’t specify a quantity for a reason but it’s good to have a guide 👍
Great video just done an oil change on my duke 390 2014 bought it a few months ago and noticed when i drained the oil there are black specs in the oil im guessing carbon deposits? Has anyone else had this problem? Other than that mine is still running flawless but im hoping my engine doesn't blow lol
Did you replace the screens or did you just clean them? If you cleaned them, how did you do it? Did you use solvent or something?
I didn’t replace the screens. Solvent and compressed air, but you are looking to just remove any metal or sealant so it’s not difficult.
@@MotoMirius thanks for all the great vids on the 390, it’s a great bike and your vids are super easy to follow and informative.
Can you make one video ? On how to lower the seat height at the lowest . Thank you....
Lowering the seat height means fitting the lowering kit. I don’t have the kit. If someone were to buy the kit I can show how to fit it. Skäl. David
David can i ask when do you need to change the two mesh filters and how do you know if they need changing?
Filters should be pulled every oil change. You can wash them off - if the mesh is damaged or looks like its starting to clog then change them. There is no harm in changing them every oil change if you want.
I noticed that you use rock oil oil, is it any good? What rock oil product is it? Synthesis or guardian?
Rock oil has a good reputation. I use both systhesis and guardian in my bikes. I've also used one of their more off road spec oils for this bike. If you look at their website (and the same is true of most oil companies) they have a bike finder which will recommend oil for your bike and you can then choose which suits your use and budget. The more you blat the bike, the more you should spend on oil. If you just cruise around town trying to get the maximum mpg then guardian is fine.
Hi! Do you stayed with 1.7L or you added more? Thanks in advance.
I always add oil to bring it up to the right level. Some people like to measure it and always put the same amount in, and that works for them, I just add oil until the level is right.
indian duke 125 bs6 oil capacity ..and grade.. and the oil changeing km.. please bro??
I don't have the oil capacity for the125, it will be a little less than the 390, but the grade is the same as for the 125 (and pretty much any other bike). Just watch the sight glass as you fill, you don't need to measure it.
Hello once again my friend! I wanted to ask you if you d remember which wrench skate tool SIZE do i need in order to unbold the oil filter cap

Hello sir. What size hex key allen wrench tool and nut drivers did you use? I have seen countless vids, but no one discusses the size tools. I need to buy tools for the Philippines. Planning to buy the Duke 390 when I arrive in June. This information would be so helpful. Thank you kindly.
Hi. I have listed tools before but it is a pointless exercise as a basic tool kit will cover everything you need. Basic tools are an investment - I am still using the same spanner and socket set that I bought thirty years ago - once you have bought them, you will use them again and again. Skäl David
@@MotoMirius Thank you Moto. Yes, I have been wrench turning for 30+ years. For those others just looking to buy tools to change their oil - you will need allen wrenches and socket set to do this job. Specifically, 3.5mm and 10mm for removing the cowling. The drain bolts will take 8mm, 13mm, and 18mm. KTM, from what I can tell, are all metric.
So, what I took from this is that you only replace the actual oil filter. You don’t replace the screens. At what point or kilometers will you have to replace the side and bottom screen filter(s)?
Screens can be replaced at the same time, but normally just cleaned - replace as and when needed - dirty, damaged etc
Hey David how many miles or km do you suggest doing the first oil change at
Hi Brian. First service is 1,000km or 620 miles. You could change the oil before that but it will take that long to properly flush the oil channels out of all the swarf into the screens that they don't bother to flush out at manufacture. Skäl David
Hey David one more question do you have to replace the screens and o rings every time you do an oil change
I would only replace the screens if they need replacing. O rings shouldn't need replacing as they are lubricated and reusable.
Is it a problem if there stay some “old” oil in? Or is filling the most with new oil ok?
There will always be some old oil left in the system. So long as you follow the oil change process it should not be an issue. Skäl. David
Moto Mirius thanks! Is there any way to make sure i did it correctly?
If you followed the process, changed the filter and checked the screens then you did it correctly.
Do u use full synthetic or semi synthetic does it matter
Both work - so long as you buy the right ones. Full synthetic supposedly can be changed less often but is more expensive. If you hammer the bike a lot then synthetic can be a good choice, but very much swings and roundabouts - nothing wrong with either, more important to change it to be honest.
What torque wrench messures 12nm? The only ones I can find is 20-150ftlb
That’s where torque wrenches get expensive. You need at least two if not three to cover all the range you need. In practice for the low range just wrist tight with a short wrench is fine. Skäl. David
Hey! Do you know are there separed gearbox oil in the engine of duke? Or is it the same oil everywhere? Thanks for help!
No separate oil. Very few modern bikes have a different gearbox oil - those that do are mostly US bikes such as Harley, or old copies still being made in say India of old British bikes - all of which are running very old engine designs
I wouldn't have done it better myself!
That’s because I watched your video first brother 👍😂
good manual, thank you!

It depends on the year. On the later bikes the strainers appear to be the same parts but on earlier bikes only 390 and 250 appear to share both the same strainers.

@@MotoMirius never a problem.
What do you just to clean the screens?
I blow them off with air, but you can use any bike friendly solvent, if you don't have air. Some use brake cleaner but you aren't trying to degrease them, just remove any particles from the screen.
@@MotoMirius thanks for the reply
my forward facing drain plug is seized to the case. The side one is serviceable. Should I be worried?
The screen can get clogged so it's best that both drain plugs are useable. On an older bike the risk of the screen clogging is lower so you might get away with it. It's impossible to quantify the risk - it might never be an issue - but if you ever get an oil pressure warning on the dash then you need to get it fixed.
@@MotoMirius thanks for your reply. Even at the shop they gave up on trying to get it out. So just going to have to deal with it I suppose.

@@MotoMirius Thank you, all the best
Sir I changed my Duke 125 oil I used motol 20w 50 oil it is safe or no safe
If you are in a hotter country and that is motorcycle oil not car oil then it should be fine. 20w50 would be too thick for colder countries which is why most motorcyle oil is 15w. 20W50 is used in some older style motorcycle engines such as Harley where the oil passages are bigger.
My manual says 1.7 L 15/50w from end of 2017!
Yes, and I said that you then need to top up which will take you up to 1.7l - depending how much oil was left in the engine.
I don’t have a torque wrench 🔧🙁. Will this have a detrimental effect on the putting back together? Thanks in advance
Most people don't have access to a torque wrench. Do it up lightly so it touches and then just a little more. If it leaks nip it up a bit more - I recommend not putting the bottom plastic on for a few days so you can check it. If you overdo it you'll damage the alloy plug and need to buy another (not that this has ever happened to me...) Skäl David
Moto Mirius thanks 😊
What kind of oil did you use? Thanks
I use an oil made by a UK oil company. You should use an oil which meets the JASO T903 MA2 standards. Most oil manufacturers will recommend an oil for your bike on their website. KTM recommend semi synthetic and since they have a sponsorship with Motorex recommend Motorex Formula 4T. If you are within the warranty period on your bike then I would recommend sticking with the recommended products to avoid any risk of challenges. I'm currently using Rock Oil Synthesis XRP Off Road 10w50. Skäl David
Hello sir Can I use 15w40 instead of 15w50 engine oil?
Oil weight is mostly temperature related. Here in the UK 15/40 is commonly used but if you ride somewhere hotter this could be a mistake because the oil may not offer protection at startup.
This video may help in making your choice th-cam.com/video/ivm9T47zUOw/w-d-xo.html
I am having KTM Duke 125 what grade oil I can use for my bike
KTM recommend 15W/50. Make sure you use a motorcycle grade oil not a car oil.
When you say oil needs to beat certain temp, can I just turn the bike on let it tick over for a few minutes?
Yes, that's fine or ride it up and down the road a couple of times - it's just to get it pumped around the engine and warmed up.
@@MotoMirius spot on thanks alot!
Hello! I have a problem. Namely, I poured 2 liters of 15w50 oil and it is below the minimum. What's happening?
It will take two litres of oil if you have changed the oil filter. Make sure the bike is properly upright and at the right temperature - if the bike leans away from you the oil will not be visible. Skäl David
How long would you say to run the bike before starting?
You have to run the bike before starting. To correctly read the oil level you must bring it up to operating temperature which you can read on the dashboard.

How often on ktm 125 duke 125

Dear Sir David,
May i ask a question? I had a problem. Could you give a suggestion? I have a KTM Duke 390(2017). Last day i started it and everything was normal at start-up. I rode it about 2-3 km then it gave a "Low Oil Pressure" warning. I checked the oil level, it was a little bit below the normal level. I changed oil and oil filter. Warning disapared. i didn't used 2 days but today i rode it again. At begining everything was normal then again i got same warning after 3-4 km. What could be the problem?
Please help me?
Kind regards
Was the oil normal when you changed it? If it wasn't then there can be a failure of the seal on the water pump. Sometimes the oil pressure switch can be faulty and gives this error. Otherwise you should get a KTM dealer to check the oil pressure. Good luck
@@MotoMirius Actually KTM dealer is a bit far away to me so, i got some helps for chaning oil and oil filter from a local mechanic. I told him "low oil pressure warnning". Probably he didn't understand me. He mixed it with service warning. I will call KTM dealer as soon as possibly. I will tell them about your advides.
Thank you so much.
@@erhantiryaki If you don't have a local KTM dealer then find a mechanic who has the tools to check the oil pressure. This error is often a sensor failure - but oil pumps also fail so you really shouldn't run the engine until you've identified the fault.
Sir Sorry to say that you have need some oil pour in oil filter then you fit that.
Whilst you can do that, KTM do not agree with you. The process I have shown is as described by KTM. Filing filters with oil before fitting is not usual with this design of filter, and with many filter fittings not even possible. Skäl. David
Yes if u fill the oil fiter with oil it will be good for the engine,but in this case it doesn't matter because The filter housing holds very minimal amount of oil and second it is difficult to do that and don't worth and you can't fill it to the full anyways so it doesn't matter
Sir i have ridden my Duke390 about 4500km since last service it has taken about 300ml of engine oil topup overall, there is no leaks at all no smoke from exhaust still the level goes down. Is it normal for ktm?
Engine oil motul7100 10W50
If there are no leaks and no smoke from the exhaust then the level should not go down - but some loss is normal. You do not mention how long ago your service was.
How much oil for 125cc 2021?
1.2l to 1.5l depending if changing filters etc
Do you know how to remover the sight glass. Mine has white residue on it. I want to take it out to clean it. I'm wondering if I just remover the circlip and it should pop out but I am not sure.
White residue is normal during cold weather and should clear up once the oil gets hot and the water reabsorbs. It should come out but I've not tested it myself - I plan on checking the clutch at some point in the not so distant future so I should find out then.
@@MotoMirius thanks for the reply. It's been like it since I bought the bike. Last year. I have done a couple of oil changes but it has never cleared. I am due to change the oil again over Christmas so may investigate myself.
What’s your oil change range interval David?
Daniel Mak typically it will be about six months Daniel. I may extend that on a bike I don’t use a lot but it’s important not to let used oil sit in an engine for too long.

i have a ktm duke 125 2019 model 4 months after the first service engine light kept turning on an off was told its probably a faulty oil switch then it would come up and say low oil pressure but oil lvl was fine plus oil had only been changed 3 to 4 months ago from the first service. went to a garage to have it replaced they took it out had the part on order told me it was safe to ride 10 mins down the road and engine blew. had to buy used 2018 ktm engine had this 1 installed only had 1466 miles on it now im at 1765 ish and im getting the same problem engline light and low oil pressure engine sounds a little different also i have no idea what this problem could be and how this can happen the same way in 2 different engines can any 1 HELP ??
When the dealer changes the oil, they are supposed to also test the oil pressure to ensure that oil pump is working properly. You also have to ensure that the oil level is correct - this is a dry sump type engine as far as checking oil level is concerned. If you check the oil level with the engine cold then you will not have enough oil in the engine - and it will get damaged. That you are getting the same problem suggests that the oil level is being checked with the engine cold. If this is a KTM dealer then make sure that they have tested the oil pressure. It might be time to find a more reputable garage who know what they are doing.
@@MotoMirius im kind of stuck now cant ride it closest KTM dealer is over 30 miles away... the engine oil lvl is fine i know how to check that ive left the engine running for a good 10 mins and checked the oil lvl b4 this happend just over a week ago as i had a long trip to make now i have this problem (low oil pressure) whats the best thing i can do ? im pretty sure i can fix it myself i just need to know the problem.. could it be oil pump?
@@404hotshot low oil pressure where the level is correct has two most common issues - blockages in the oil galleries - most often clogged filter or screens, or a faulty pump. If you changed the oil and filter then the most likely culprit is the pump. Oil pressure sensor is also a possible culprit so you could swap that out as well - testing is possible but mostly tells you if it works, not if it works at the right pressure.
@@MotoMirius ok ill replace all 3 i hope the oil pump is not to hard to get to ill buy a oil pressure test kit as well and go from there than for your help
Great Videos 👌
Thanks Bryan. Much appreciated. Skäl. David
Subbed like blanco…
What engine oil did you choose?
Rock oil is my normal choice Daniel. Currently it has Synthesis 10w30, but I might upgrade to one of their higher spec alternatives. Skäl David
@@MotoMirius why 10w 30? Whats the reason you made a choice 30, not 40, not 50 as manual says, or even 60?
Hi Daniel. KTM spec is 15w50 but here in the UK it rarely gets hot enough to justify putting in an oil with that heat rating but it does get cold enough that I’m comfortable enough dropping below to 10. Rock Oil who are a UK oil manufacturer recommend 10w30. Skäl. David
Can you define hot for the duke?
Daniel Mak hot would be tropics, places like India. I have a video on oil choice that might explain my views on it. As I said in the video, using the recommended oil by Motorex is what I recommend. But the right oil for say India isn’t the right oil for Alaska, so there is room for deviating from recommendations - at your own risk of course.
В мануале написано не 1.5 а 17 литров
Если вы заливаете 1,7 и масло слито не полностью (это не стандартный двигатель с мокрым картером), вы можете перелить - послушайте, что я говорю - вы добавляете 1,5, а затем доливаете до нужного уровня.
@@MotoMirius Я с Вами не спорю. Просто не давно купил такой мотоцикл и прочитал в мануале что масло необходимо 15W50, 1.7 л. Но у меня Duke 250. Может в нем 1.7? Мне нравятся Ваши видео. Уже посмотрел несколько.
Спасибо www.ktm.com/en-us/service/manuals.html предполагает, что у него также есть 1,7-литровые Duke 250 и 390, имеющие одинаковую нижнюю часть (не обязательно в отношении деталей двигателя), так что это не удивительно.@@Kuper133
@@MotoMirius Спасибо что Вы отвечаете на комментарии. Я смотрю Ваши видео для своей пользы чтоб обслуживать свой мотоцикл. Это мой первый мотоцикл. У меня нет опыта. Поэтому Ваш опыт для меня бесценнен. Я подпишусь на Ваш канал.
So many things wrong in this video
You will need to complain to KTM then.
