In this video, we talk about some of the tools you'll need to set your sag. We also give a brief overview how to properly set your sag on your bike.
The reason that I'm recommending to stand up while tagging the sag adjustment is that it's a repeatable measurement. I think it's more accurate that sitting down on the seat, because it's hard to sit in the same place every time. If you follow the principles outlined here, you'll get things close and then you can fine tune to your liking.
Make sure to confirm you have the correct spring on the bike for your weight. Most of these bikes come with springs designed for folks that are between 155-180 lbs without gear on. If you weigh more than this, you will need to outfit the bike with a heavier spring. If you are a lighter rider, you will need a lighter spring to active the correct amount of sag and pre-load on that shock. This will make a HUGE difference in the handling characteristics of the bike. Trust me :)

Awesome vids Kyle ......bought a 300 exc a few months back after not riding for a number of years (Business, Family Kids etc) loving it again !
Being a used bike it has been tampered with over the years by tools that don't really know what they are doing, I rode it about 5 times before setting the sag to the correct height...can't tell you how much of an improvement it has made....it was only 12mm too low, I raised it & dropped the bike down at the front 5mm & it is like a different bike now, turns so nice on single trail tight stuff. Thanks again for the info you provide in your vids, cheers from Australia
+Bret KTM Thanks for watching from Down Under!
I may be wrong on this...but I think you set your particular race sag first....and then check static sag to see if you have a correct spring for your weight/riding gear.
Hey man, just like to say thanks for taking the time out to make these videos. I'm getting back into ridding after a decade off the bike and your videos are fresh and help me re enter the sport.
Thank you. Glad to help.
instead of cutting your fender and marking it up with sharpie, couldnt you use a little piece of tape
I love that you rep SKD and BCM! I also love your channel. Just stumbled upon it a week ago. Thank you for taking the time to educate people.
+B Smith Yeah BMC and SKD are pretty cool companies. Guns and bikes are my main interests in the last 5 years.
Mine as well. KTM in the bike world and BCM in the rifle world. Good taste haha ;-)
Excellent video, brief, informative and answered all my questions. Just purchased a Husqvarna TC125 for my son, he is tall but light. This helped a lot. The manual, says replace spring and offers no help with adjustments
Glad to help Mike.
Yea thank you this helped me a lot because I got a KLX 140 and a RM250 and this helped a lot
Now I really want to check out the sag on my bike! Body positioning could cope with some of the issues of not having enough sag when your in the sand or tight terrain. When you crack on the trottle in the perfect gear that creates more sag and can be adjusted with body positioning I believe. I was riding double with my fiance with the 2 of us weighing 265 on my 2014 yz250, I only adjusted the screw settings both front and rear 5 clicks to the +. Now riding solo with the same settings it works out perfectly. Im going to see if the settings I have are even close to what Yamaha says haha. I love all the videos, it really makes me want to make sure my bike is perfect before every ride so that I can be a better rider and worry about improving my skills instead of wishing I changed the oile and cleaned the air filter. It all makes a difference when you expect your bike to perform a certain way and it doesnt because you didnt do proper maintence.
I've got that SKD sticker on the back window of my car. I went from the gun world to the bike world and still found my people, love it. Not to mention the BCM hat.
This has to be one of the most helpful videos out there.
+Danny Little Glad to help out a bit Danny.
Can you please make a video about all your personal settings on the fork and shock? Thanks!
Lol instead of sag I at first thought it was called" Setting rider swag" 😂😂😂
It's a similar process to set your swag!
+Dirt Bike Channel Haha yeah! Love the channel bro! Keep it up! :)
Wazzup Swag or a rider's swagger is always important. Got to swagger to show rider confidence. Lol.
Weight transfer is only part of the handling difference. When you change sag, you change the steering geometry. When you decrease your sag, you decrease steering angle and steering becomes more nimble, but twitchy.
Increasing sag will increase the angle and give it a cruiser like feel, slow but stable.
Exactly
AWDn0t2 you're referring to squat I believe. Unless you are making drastic changes it shouldn't have any effective result as far as changing the steering geometry in any significant way. On paper yes but actually riding the bike because you're in and out of the seat under acceleration deceleration and braking, those changes wouldn't have any significant effect.
Finally! This is what I was looking for, a full explanation of sag adjustment. Thank you
+Cameron Fisk You are welcome.
I know it's off subject but love the hat. Great company
My owners manual on the 2017 450 six days says to remove shock first to adjust sag and make sure spring is rated for your weight with gear on.
Painters tape instead of marking your fender is a good alt
+Cowboy2659 whatever works.
rubbing alcohol, or a quick squirt of deodorant, will get rid of the marker pen..
***** alcohol makes the plastics brittle and more acceptable to cracking or breaking on a crash. yeah there are lots of ways to get marker off. but a piece of painters tape and then the mark no issues just stating what i have learned in the past. also a dry erase marker will remove the permanent mark off. but i'll just refrain from commenting anymore.
I like to use a marker so you have a consistent reference
Nic video however I'd read that you should check your static sag only after you have set your rider (race) sag as you are basically trying to ensure that once you have set the sag for your weight that the static sag is still within the range it should be. If static sag is out with the specified range then you should be looking to change your spring for one that allows you to set your rider sag correctly whilst maintaining the correct static sag.
Tony Anderson You are correct. In this application, the sag was very close with my weight, so the static sag was still in spec.
I like how you explained how the sag affects riding style of bike. can you a video existing forks compression and rebound?
+Jason Gordienko Glad to help.
I wanted to know how to set the sag with a tape measure at home, you had the tape measure but you didn't show us anything on how to do it.
I just bought a '17 KTM 150 XC-W. The bike is just a little too tall as delivered. I'm 6' tall and have a 32" inseem. My question is, can I just set the sag so it sits lower, or should I also use a lighter spring? I weigh about 195, I don't race, I just want a good fast trail bike. Relaxed turning and high speed stability would be fine with me.
Byron Woodruff you can but that's not the right way. You can buy a lowering kit for the linkage.
You are probably going to need a stiffer spring also with your weight plus gear. Make sure you lower the front equal to the rear to keep proper handling characteristics of the bike. Also change the front springs to match your weight or the bike will dive too much.
Great vid once again . Front suspension next do a vid on that . Love your vids there so helpful thanks
What way do I turn this so the bike is lower??
What bike should I get I’m 4’11 (90 pounds) and only 12 years
Good video on Sag.
Can you make a more complete suspension setup video. Compression/rebound clickers etc? Thanks!
I'll go get dressed, while some else does all this for me!👍🏍
Skd tactical decal for the win!
Exactly! It makes him SO much faster thru the corners..When I was in the automotive speed equipment business we used to laugh at the guys with all the decals. If you ain't getting contingency money why advertise for them. Just my 2 cts. Good video and explanation. Thanks for posting it.
nice explaination, thanks! any advice on how to set up correctly the handlebar? on my 500 EXC the stock setup is installed on the holes that are backward, and once i stand on my peg i feel they are a bit too low. Should I use risers?, change the handlebar? or just change to the front holes and rotate them a bit foward?... and other thing, in the manual, the specs of the rear spring is for a rider of 165-185lbs, I'm weight about 218lbs without my gear. Can I just change the spring to a stiffer one to match my weight without doing other setup on the suspension? thanks!
+cadwarrior im tall and i brought 25mm risers feels heaps better im less crouched over the front when standing
I need a little help.
I have a KTM EXC 250 2015 EU model. I liked to adjust the suspension for my weight. All equipped and ready for a ride, I weigh 100 KG.
If I change the standard springs, for some that fit my weight, will I have to change anything else in the forks and rear shock?
I don't know where to set my sag I weigh 130 lbs without gear and I have a yz 125 that's really tall for me and when I get on it my weight doesn't weigh it down enough I think the shock is too stiff for me
Love the video it helped me a lot! but out of curiosity what type of oil do you run?
Hi there, excellent video as always. Can you help me clarify on something: On the KTM 125 SX Manual, the section on Sag adjustment are broken into the same two topics (Static vs. Riding Sags). From my understanding, adjusting the coil is only meant for "Static" sag; whereas the manual said for Riding Sag adjustment, it has to come from installing of a different spring (of a different tension rate). My question is: wouldn't your instruction on the riding sag adjustment end up changing the static sag in advertently? This is where I get confused.
^^this^^
Spring rate determines rider sag. Preload adjustment determines static sag.
Great vid! I have a totally unrelated question. I like my bikes clean and I see yours is always cleaned up in your videos, what products do you use to clean? also do you use a pre treat prior to riding to aid in post ride cleaning?
Thanks.
My secret is just good old fashioned elbow grease. After every ride I come back and spray it off with either just the hose, or a pressure washer (if it's really muddy). I then use a hand brush (like $10 bucks on amazon) and a bucket of soapy water to scrub it all down. I'll then rinse it off. The real key though it using a Chamois to hand dry which make a HUGE difference in how it ultimately looks. I'll usually finish with blowing out all the hard to reach areas with compressed air with my air hose. That's it. Thanks for watching!
rexdadpapa Mr. Clean Magic Eraser BEST product I have found to clean bikes. We ride in areas with a lot of red dirt, it stains everything. Dawn and a rag or brush won't budge it, the Magic Eraser with a few rubs, the stains come right off.
You do a ever well job on your videos. Could you one on working with your clutch and when should you use your clutch or when you can lay off of the clutch? Yall have helped me become a better bike owner. I own a 93 yz 250 and a 2013 350 ktm let me know please and thanks for your time.
PuRE Production Yes, we have that planned for a video later this year.
Dirt Bike Channel i have an 87 kx 250 it deflects and is not stable thru sand or mud. can u suggest anything? i can say steering bearings are new oil too and forks are 5mm in the triple clamps. oil height is 120mm.
Great video. I'm not that serious about my bike cause I shear it with my sons . So it's a bike for fun. I luv the information you provide. It's top quality. I've a Samsung S7 so it spells for its self lol. plus I'm a shit speller lol. Keep up the good videos I know you put a lot of research into them and so I respect what you think. Thanks Again from Ireland Jon and family.
+John OReardon Thanks John. Say hi to your family from me!!
Dirt Bike Channel thank you. And same to yours. Your a gentleman. Hope your weekend is a great one. Jon & familythank you sir.
+Dirt Bike Channel is there any differnce in seting up your suspension for trail or motercross. and if there is what would i change?
Please help. I have Kawasaki Ninja zx636r 2004 year. I notice that my bike is too soft and that it is very low. The owner before me has so set the suspension because it is low. How to Raise rear end on motorcycle? All parts are original and nothing is changed. Thanks in advance
My tire is hitting my fender I have black tire marks on the rear fender..... what should I do?
It’s a 2001 RM125
Thumbs up for the BCM hat!
what about gas?? wen you take the mesurment full tank or 1/2 ????
Increasing your sag should also give you better traction up that difficult climb.. Along with decreasing your rear tyre pressure..
Cut a notch?! Full tank?!
Ugh. I hope nobody actually cut a notch in their bike fender.
You probably want to measure effective sag with half to two-thirds of tank of gas since that's probably the range where you will do most of your riding.
Great vid! Very informative. Thanks for posting this.
Dave Heinrichs You are welcome. Let us know what other topics you'd like to see in the future.
First you said between 19 and 32mm...then you say between 29 and 32mm? Which is it now?
Wouter Du Plooy it is a bike dependent dimension. check your manual.
Good video.
However i thought the sag tools were designed to be put into the hole of the rear axle ? maybe there are different methods to it. Either way good tool.
This particular bike didn't have the hole. My other bikes do though.
Dirt Bike Channel Ahhh okay, that makes sense. Well good that you made due with what you had ! good stuff.
Dirt Bike Channel I need to now how to make the dirtbike higher bc the 2002 yz250f is very low to the ground and I want to raise it up high?
When you do the math do you subtract your overall sag when the rider is on the bike from the static sag or from the number you got when the shock didn't have any weight on it?
It makes sense to be from when there is no weight on it so you get the 100-105mm overall sag.
Thanks!
What? Just figure the difference between the two readings.
@@bertbenny7249 There's 3 readings. Free, static and rider sag. He's asking which two measurements are used for sag number. Which is the very first measurement (bike on stand) and subtract the last measurement (rider on bike). That should be around 105 mm
Why mark you fender? I would put tape so no marker on plastics
what if you take it off and it takes paint off
Paint??? I Gotz No Paint On Me Fender....BaHaHaHaHa.....
@@zackjohnston858 You dont ride dirtbikes do you? lol
I weigh 250. should I go with a heavier spring or a spring more fit for my weight?
Yes, get the bike sprung for your weight for sure.
cool video like always 💪
Is their a difference if you measure from the swing arm to under the rear fender instead of the side
Ktmracer Technically, you can measure to any two points on the back of the bike as long as you've got one point representing the wheel and another point representing the frame. All you are really doing is measuring the how much the suspension moves under your weight and the bikes weight. What you want to do is just find a place that is easy to measure repeatably. Most guys find it's easiest to do it the way I've shown, but if you have a system that works well for you (using different measurement points) it should be fine.
So many videos about adjusting rear sag and none about the front? How about a setting up forks video??
so i want to get a kx 250f 4stroke, but it is a little tall for me, i am arround 80-90cm, and it's height is around 95cm, i wheigth about 60/70 kilos, can i lower it? without need to buy a new string or lossing control?
+Gamerz HD You do realize that you only have to have one foot on the ground at any one time, right?
yeah iknow, but is always better 2 than one, using one takes abit of time to get used to
and sometimes 1inche can make a diference between crash and no crash
Excellent videos !! and the image is fantastic, can you tell me what is your camera.
Thanks
Most of my shots over the past 2 years have been with a Canon 6D. In this video I'm using a 50mm, 1.4 lens on it. When I'm out on the trail, I typically use a wider angle lens. I have a GoPro, but I don't use it's footage as much since it distorts things so much.
Rocking But Steady Thanks, and You are right about the GoPro, too much distortion
hands up great videos man love them :)
Thanks Rip.
so if I adjust riding sag, won't that change your static sag?
+Jason Gordienko It will effect the static sag. Static sag is an indication of whether or not you have the correct spring for your weight. If the static sag is too far off from spec once your riding sag is set, then the spring needs to be changed.
+Dirt Bike Channel thanks
Dirt Bike Channel Rider/Race sag needs to be set. Then Static sag is checked to determine if the bike has the correct spring for your weight. So no need to check Static sag until Rider sag is set properly. The order is important.
@@human1513 thank you, I've thought this for years but nobody could awnser this question, made me feel nuts! Lol
Informative and to the point.
Thank you Sir,
Isn't that sag tool supposed to stick in the hollow point of the axle?
+theninja001 Yes, but this axle doesn't have a hollow point. My other bikes do, but this one didn't.
Ah, gotchya, well I just used a tape measure that had metric, but I think I might invest in a sag tool!
right at 8:19 it was then that i KNEW you were a mormon guy.
👊🤣🤣🤣👍🍺 im crying 😂😂😂
Great video, really helpful thank you! 👍
I have a dirt bike converted to supermoto and I want the seat height higher and the back suspension stiff. What should I do?
+grosblyth tighten the back spring
Avenger 21 That wont make the seat higher.
add some foam to your sear
+grosblyth Stiff suspension is more about your valving and clicker settings than spring rate. If you want your bike to be stiffer and more responsive with less dive on the road, look into having someone reshim your fork and shock. Going up in spring rate is primarily going to change your ride height/sag, which may or may not be what you want.
can some one help me with this i just bought a used bike and the low speed clicker and the high speed nut dont spin independently. For example if you try and turn the low speed the high speed turns with it at the same time. The bike a a 07 yz125 i was wondering if there would be anyway to fix this or do i have to buy a whole new rear shock for 900+
yamaha yz you could try to hold one with the screw driver and the other with a spanner. If that doesn't work try bringing it into the shop and have them check it out, you don't always need to replace the part, it can usually be rebuilt.
yamaha yz spray some wd40 or other lube onto the threads to ensure the nut is not stuck to the screw.
Do you have a video of all the mods you have done to Your 300xcw?
Ricardo Garcia Check out this one. It shows most of the mods. th-cam.com/video/oWfHNP4tqPE/w-d-xo.html
Would decrecing the sag help stop speed wobbles??
+Corey Hammond I'm not a suspension expert. Having said that, getting your sag set properly will never hurt anything. Each bike/rider is a bit different. The best thing to do is start testing on your own by playing with your clickers once you have the sag set in the right place.
Ty for video. Very helpful
Does weight matter when you are in motocross
+Kaylan ramrup Yes, weight matters.
+Dirt Bike Channel I'm 180pounds would i be able to ride a 125
your bike looks brand new!, not even a small scratch on it, do you buy new plastics after each ride????
cadwarrior I'm pretty sure this video was taken right after I got a new fender on the rear. I ripped the stock fender off doing wheelies just before this. I ride hard and if I break something, I'll put a new one on :)
Dirt Bike Channel
that make sense!, I do like nice looking bike too!! like all your videos! verry informative! I ride an XR400 and look for new taste and lighter bike, I suppose that there is a huge difference between the KTM300 xccw and a Xr400!?
Yes, those two models are VERY different.
Nice I can do big wheelies on my dads kx250f
Dirt Bike Channel awesome video on suspension set up i have an 87 kx 250 the front suks deflects off rocks any ideas? i changed the oil. springs are stock. thanks.
What mixture do you run? 30:1 or 40:1?
Henry Bourguignon 100:1 with Amzoil Saber oil.
Bravo Company, Hell yeah!
How do you play around with your front forks??
Jackson Gardner Just using the clickers...
Does setting rider sag help with seat height adjustment?
+Yousif Al Sarraf Not much to be honest.
Setting rider sag will definitely change the seat height.
What about when the bike is lowered for we short-arses?
Are you shorter than 5"6?
Just a smidgen over 5'-6"
Good info, thanks mate
if i am 5 foot 2 1/2 there would i put my front suspension and back
badass SKD sticker
I'm 5 foot 3 and am a good rider would I be able to ride a 250
CYD Critical yea you will be fine riding but when you come to a stop on trails where the terrain isn't smooth it can get difficult
Hmm...someone COULD developed and sell some type of optical laser device where you clip on reference targets and then aim the device at the bike so it can "see" the reference targets ....then just a matter of going through the exercise letting a computer via the laser sensors record what takes place... Good idea?? With lots of data a program could just tell you what adjustment to make after simply "watching" you go through a set routine of compression movements....not a lot of thinking or anything! Just set up the device and go through the motions! And then? Obey the instructions making changes....and then recheck until it indicates "good'
I'm at Jamaica I am 10 and I want a KTM 85 4 stroke or 2 stroke can I get one please
Is that hat some kind of rifle company? Were you in the middle east?
Great vid .
Have any on front fork suspensions ?
+Danny Little No, I haven't done one. Suspension is so arbitrary from one person to the next...
Great info thanks
Thank you!
thank you very much
i thought you set the sag according to your body weight? IE: a pre-determined measurement, which is adjusted according to the riders weight?
Setting the suspension up to manual specs, is just setting it back to standard setup..
Setting the suspension according to manual isnt actually setting anything up, as a light person would barely make the suspension move when on it, So will be too hard for them..
and the same goes for a heavy person.. a heavy person could bottom out the suspension and cause the rear tyre to hit the arch..
So thats why i thought the suspension was setup dependant on the riders weight, and not manual stock specs..
The rider is IS set to the riders weight. Watch this again :) You only check the static sag to see if you have the right spring after your rider sag is set up.
what is a spindle
Ben Savage
so after all that its rider preference. wow
Plus I ride a lot in sand because I go out to dumont and glamis
But yea thanks a lot because last trip out before I saw this video, I dumped my 140 hard while tryin to make a sharp turn on a dune
Also how tight should my chain be on my dirtbikes because I feel that they are too loose but yours didn't look really tight
subbed
Thank you!
Man its hard to take advice when your using the tool wrong.. The pin goes in the axle on the other side so you get the same reading...
Didn't remove the plugs on this axle, but you can still get a good measurement the way I'm doing it. You can do this with a tape measure too, so the tool isn't important. The concept here is the main thing. You just measure from the same spot each time. It works.
All these settings people speak of is fine but your going to hear it here and here it now. And that is. you need to set the sag where they say to start with but then you ride your bike and check the cornering. If your bike wants to push to the outside in the corner. Go back to the truck and crank the spring three full turns tighter to put more weight on the front wheel. Go back out do the same corner. You will see it is easier. Turn the spring until you can rail the inside corner but start with it pushing out so you know how far you came. It will happen. Those of you that heed my advice will soon question if you want to share this information with your friends. I promise. this will make your bike corner like never before. The sag setting is not the bible as everyone speaks. your bike handling is a safety item not a perk. Just like the government. they only give you bits of information. haha
Which is of course what this awesome video states pretty good nformation but in cave man terms. if it pushes. tighten the spring until it stops pushing. Good videos guys. Watch them all. I went out and did these adjustments and was so amazed how much difference it made I walked around the track joking. oh your clutch does not work. tighten your sag. what. your brakes are out. tighten the spring. best adjustment ever!
Thanks for the tip.
sorry but the video is not good. He states the static sag tells you if you have the right spring rate. But first there is not just one spring for each bike and second with how much preload since static sag depends on preload he didnt say a damn thing about the static preload on that bike
+q062am I guess you don't understand...
I have to agree. Static sag is soly based on your sag setting. You cannot check your static sag without first setting your preload. Because static sag will tell us AFTER setting our preload or sag, if we have the correct spring rate. Example. In factory setting you may have a static sag of 30mm, ok that's exceptable. But if you weigh 155 lbs your probably going to have to add preload to get the bike to fall into that 100-105mm sag measurement. So now what was 30mm of static sag has most likely become 20mm of static sag which means your rear spring is over sprung.
And let me correct myself. You would have to take away preload if your lighter. Not add. Adding will make it stiffer. Removing will soften. However in an over sprung scenario this will make your static sag number smaller.
I'm 5foot8 would I be able to ride in a 250
Adrian Lopez youll be a little short, especially for a KTM because they ride high. But find a friend with one and sit on it to be sure before you buy. This however, does not mean its the best bike for you
Adrian Lopez I'm 5'3" and I ride a yz 250. It's tough but possible
Of course you can ride a 250 it is your skill level, comfort and style that determines what you should ride I am 5'8" but I have been riding 250s since I was 14 I am now 53 and shrinking lol. I ride a ktm 300xc-w now
Do make your video some more clear and audible. Informative one
mm?
Did he just draw with sharpie on that bike😫😫😫😫
+MW3 Gaming Yes I did. Hardly noticeable. Sometimes a carve a little line with my knife.
