Ridden for 40 pus yrs does not make me an engineer LOL I got basic understanding of bikes and the physics of some bike things but riding gives good riding experience, I know a few things but not an engineer by any definition. 4 yrs of engineering would be better than a ton of riding experience but 4 yrs of engineering does not replace riding experience as far as riding goes. I do a lot of things and did and until I took a beginners racing class at a track by racers I did things and did not even understand why or how it worked it just did, but knowledge is definitely good. understanding how things like counter steering works and trail braking, and manual speed shifting works is cool. Not to mention how to load and unload suspension for corners and how to load tires. I was told just do not surprise the tire before making a direction or braking change and it worked but until race school did not fully understand the physics of it. Still not a physicist but basic grasp of what bike is doing in transitions, best rule is this smooth is fast. jerky motions slow you.

Hey! Daytona 675 owner here, although it sounds like the tripple would be a not so smooth engine it actually is one of the smoothest bikes I’ve ridden, vibrates a lot less than a few of my mates bikes. Sounds nicer stock than any other bike and honestly the power delivery after 4k makes it feel like it’s got a vtech engine in it, highly recommend any bikers to have a go on a triumph because the engine is amazing and their bikes amazing handling, 10/10 hit the spot for what I wanted in a sports bike
I've ridden Daytona 955is for over ten years now and I agree entirely. Most of my riding is highways long distance and the triple is just so comfortable to ride with heaps of torque low down, but great power as it revs out.
I've got '23 765 RS and it is the peachiest engine! The low down grunt, the power right up to redline and the noise, oh the noise of the induction is intoxicating!!
Excellently explained. I've got the T-plane engine on my Tiger 900 and it really does have a split personality. Above about 4500 rpm it acts like a four, under that it's more like a V-twin, and sounds great at any revs.
In the later 60's Honda wanted to build a big bike. They sent scouts to America to feel out the potential market. They got back to Japan and said, "Americans want a bike that sounds good". The Honda 750 four was born.
It's about the SOUND.. even my old '05 Daytona 955i airbox is designed so the rider can hear the throttle bodies induction noise . The airbox snorkels are turned backwards towards the rider.. Engine, exhaust sounds are a huge part of the experience .. Those who have ridden my Daytona even say wow, what a sound .. very clever marketing tool.. visceral experience ..not sure the T-plane has any performance advantage ...this was done waay back in 2014 with Smiths Racing IOMTT Daytona 675 .. changed the firing order. Gary Johnson won on the T-Plane 675 that year.. but that was that. Sure sounded great. Always a give & take .. I think it's the exhaust note which makes you 'feel' like it performs differently..
@@carlmayer691 Only tiger haves t-plane other models has crossplane cranks. So why this video maker is like talking that all newer Triumph's haves t-plane crank. I have too -05 Daytona but it's converted to speed triple.
T plane engine is shit compared to cp3, you haver better low end torque but it sounds like a 2 cil all the way and it dies on high revs, its like 9 out of 10 owners of old 800 that upgraded to 900 preffers 800's engine
I wanted to thank you from the bottom of my heart for the knowledge you share. I'm a ship engineer and you helped me understand my profession even better than the best teacher I had till now. Best of wishes.
I'm a new powersports mechanic, 7 months into it now. This channel teaches me so much about the concepts and functions of engines, etc. I can repair and rebuild all day, but learning and understanding the theory and concepts of operation helps so damned much. Thank you for doing what ya do man!
I have a Tiger 900 and when I knew my motorcycle has such a strange engine configuration I thought this was stupid. Now I do not think it is stupid anymore. Thank you. Keep beeing probably the best channel on mechanical engineering ever.
Me too. The vibrations have a sense of character, but also frustrating. The 2025 model has better vibration control on the handlebars and seat. The heat from the radiator fans is bad in summer, I put a heat shield over them.
My Daytona 675r might have some fuelling issues atm but the sound when she's right is just the most beautiful thing. Knowing a bit more about it from this makes it even more special. Nothing like a triumph triple
Totally with you there! I've got a 2009 Street Triple and I love the engine note. When I see other triple's I know it before I even see it just by the sound.
The Petronas FP1 did use a 180 degree flat plane crank in some of their race bikes during their final season in WSBK. It was never homologated and yes it would have sounded different to the 120 degree but they were desperate for power during that last season and the other teams knew it would never be a title contender due to being a smaller capacity engine compared to the 1000cc 4 cylinder bikes being used after the change from 750cc 4 cylinder to 1000cc 4 cylinder. The petronas FP1 was never going to be a bike that got sold even though rumours that the full homologation numbers were not met, Petronas did actually build the number of bikes needed to homologate them for racing even though they never passed homologation for the road at the time. Riccardo engineering did run a number of them to try to homologate them but due to over heating of the rear facing cylinder heads and the issues the race bikes had with cylinders becoming oval due to massive heat behind the cylinders and colder air on the forward facing intake side Petronas decided it was too much of a risk for them to sell due to the liability claims they could face.. But they did use flat plane cranks in a number of bikes. How do I know?? I worked for the company that made them..
Copy and paste right off the www verbatim ...LOL Smiths tried that in 2014 IOMT Johnson's Daytona 675 ..he won...but that was a one-off engine which really had no performance advantage except for the sound LOL
@@carlmayer691 co[y and paste off WWW? The 180 degree flat plane crank has not been mentioned on the internet and was never spoken about even though other teams will have known from the sound. But the 180 degree crank was quite a bit lighter than the 120 degree cranks. I know because I worked at the company that made them. The 120 degree cranks would allow the bike to rev to about 13,000 rpm but in the end the lighter 180 degree crank engines were supposedly going to 15,000rpm and as they plugged a fresh engine in after every race the extra loads on the pistons and rods was a risk they were willing to take. So between race one and race two later that same day the engine would have been swapped. The FP1 had bigger issues than the crank, it was only 900cc not the 1000cc like the others and the reversed head was distorting the cylinders as the back of the engine was so hot with no air supply to remove the heat and the colder intake at the front would have a disparity from front to back that was enough to distort the engine during racing conditions. The flames when going into corners was them dumping extra fuel (and some oil getting past the rings) trying to cool the engine every chance they had.
Just when you thought 3-cylinder engines were really straightforward :D I kinda envy early engine guys when they started experimenting with all these geometries! And now I have a craving for some CP Chocolate Pudding :D
@@d4a Hi, waiting for you to cover. Inline 8 vs V10 vs V12 vs W16. Also IF possible cover Viper V10 vs LFA V10. Thank you 😉 your content is awesome and easy to understand.
I am no way major in engineering and all other stuff but this guy makes it easier for a dummy like me to even understand a fraction of it. Now this is what you call born to be a teacher! PLEASE KEEP THE VIDEOS COMING!!!
Thank you for this explanation. As an owner of both a Tiger 1200 and Street Triple, I was not really understanding the difference between these two engines, particularly where off-road traction is concerned. Now I see how the T-plane assists traction, and also it’s distinctive sound.
The 'flat plane', 180° Laverda triple was known for being better able to withstand race tuning than the 120°, a lot of racers continued using it long after the introduction of the latter. I think this was because the pressed-up crank was less prone to twisting its crank pins/webs out of alignment at high RPM and outputs with the 180° layout.
In the early 80s I rode a 1200 Mirage TS which had a 180 degree crank. The vibration was terrible. It was also very heavy at 250kgs. The original Jota was also 180 but I test drove a newly released 120 which was fast and smooth. I didn’t buy it because I wanted a tourer not a cafe racer. The Mirage with a120 crank would have been a great motorcycle. .
@@selbub I can imagine what the 1200 must be like, in theory at least as much vibration as a big (400) single, probably worse in fact. The RGS with its polypropylene bodywork and 120° crank was my dream bike back in the day (one of the most expensive bikes on sale at the time), might have suited your needs by the sound of it. Laverda always made their engines heavy (the twins were just as chunky), I think the idea may have been to 'mass damp' the vibration (which didn't really work). People convert the twins to 270° with some success.
I will have to admit that a derestricted Rocket3 has the most glorious exhaust note. I often hear them going past my place and they are the one bike I can instantly identify by sound . They sound surprisingly like a Rolls Royce Merlin. I know this because I once had a spitfire pass over my house at an altitude of about 30 metres.
@@paulg3336 displacement is the ONLY reason the sound is deep and throbbing. have you heard a 400 sound deep? no. because the displacement is what makes the sound rich
There's something about the exhaust note of engines with numbers of cylinders divisible by 3--3s, 6es, and 12s. There's kind of a 5th overtone in there that's lacking in twins and fours. It may have to do with the fact that there's a 3:2 ratio between the stroke and the firing interval--like 180/120 which in harmonics is a 5th overtone. It's a beautiful sound, I think.
I own a Triumph, I've always liked the different engine sound and the low down grip. I just didn't know why it was happening. My day is better for knowing. Thank you. 😊
Just commented after the brake video. I would absolutely love a master cylinder video to help understand how you can actually brake faster (and almost more importantly, more consistently). Some guys deleted the booster but install a larger master cylinder. Chasebays make great kits, especially their dual piston master cylinder with a 6:1 pedal ratio. Thanks for these video, Mark
The smaller the bore diameter the higher the braking force, however the smaller the bore diameter the less fluid it can move within the same stroke. so when you remove the booster, and swap to dual masters, they are usually smaller diameter than the single boosted master. Some people like the feeling of stiffer pedal and go up in bore size regardless if its boosted or not, however it requires more pedal force to get the same clamp force at the caliper. you can offset that a bit by increasing the pedal ratio (if space constraints allow, and pedal wont be too high)
You cannot brake harder than the tyre grip break point that all well maintained brakes without abs should easily obtain. I have never been on a motorcycle that more than two fingers are needed , stiff calipers, air , and pad/disc contamination are behind all crap braking imao.
@@MyKharli that’s true, but I don’t think that’s the question. I think it’s more about braking feel and that will be ABS independent. It’s ultimately a hydraulic system, so changing pistons on either side should affect the mechanical advantage, same as changing the fulcrum on a level.
Ran Lotus and AC without boosters. No prob on light cars with single piston calipers and small discs. Double the brake tube diameter and add heatsinks on the steel lines. 3x the amount of fluid scavenges heat from the pads very quickly. Avoid rubber hoses.
Oh man! I consider myself as a very capable technician, but I feel that I'm running to follow you. You speak really fast, and the figures in the background distract me, and I paused the video often in order to understand. It's not a complaint, just describing a fact; your videos are amazing, and I don't want to lose even a single one. Thanks, Greetings from Argentina.
Tiger 900 2024 owner here! I love the versatility of the engine, torque at low-end and all the power to make overtakes, even with a passenger and luggage. I love this engine. If you put it in sport the sound changes and it's glorious close to the redline! Does it vibrate? Yes and no, less than a 2cly more than a "normal" 3cly. Still you can do 8hs rides and have no problems.
Recently comverted triumph 3 fan here. Have had everything else and then on a goof a bought an old speed triple. I loved the engine character and the chasis, though everything else was kind of mediocre and it had no tech at all. Moved up to a 1050 rs which has all the goodies and an even better version of the engine. Eventually I'll go to the new 1200. Triples 4 lyfe.
Great presentation 👍👍 I love my 2017 3-cylinder 815cc John Deere Gator🇺🇲. I road raced a 1975 Laverda 1000-3🇮🇹 way back when. ✌️ Cheers from New Hampshire.
Your animations and explanations are better than anything we can get from the manufacturers by a mile! It's funny how the trend in automobiles seems to be the opposite... Barely can find a good picture of their motors, let alone mechanical details, images, and thorough explanations. We have to rely on third parties for that... And in that realm your videos are superior... Please keep creating them!
Wow, came to learn about the difference between I3 engines and learned a concept about motorcycle traction I have never heard anyone explain before. Great video!
Hi amazing video like always. I'm nothing of an engineer, I'm a Seaman at Bridge, but absolutely passionate about engines and following this channel for years ! I have GR-Yaris inline 3 cylinder 1.6 liter engine, and have a Triumph Sprint inline 3 cylinder 955i. Now I understand why they both sound so different no matter which exhaust ! Thanks again for this video !.
Great explanation of the differences between the design of these triples. Surprised our host didn't include a pic of the Triumph Trident from the 70s. Must point out a small mistake in his commentary, however, that occurs around 9:03. In talking about imbalances he says, "Secondary balances become very noticeable and don't require a balancing shaft." What he meant is negligible, not noticeable. As always, great presentation, information, and graphics.
Fantastic explanation of the balance challenges and the pros and cons with the different configurations. Regarding the Laverda triple, I have to point out that all the production 3 cylinder (3C) Laverdas had the 180 engine from the very early ´70s up until the 120 crank made it's appearance at around 1982. The Jota was simply one of the numerous models produced. The reason for going to 120 was not vibration but engine noise for the regulators. A 180 motor in the rubber mountings of the 120 frame is a vibration fix. The character of the 180s has ensured that there are many who have never strayed, they are a unique experience and that is a major factor for a great many motorcyclists.
I am a proud owner of a 2022 Tiger 900GT and i will say im in love with my triple engine. When i saw this video, i had to watch :) The engine really does have a split personality, a great sound and is such an enjoyable motorcycle.
Oh wow so far the best explanation of motorcycle engineering! I used to be confused about why Yamaha called it CP3 while it sounds too "smooth" for crossplane unlike CP4 that sounds more deep and rumbly, and the other side Triumph Tiger 900 sounds deep and rumbly like CP4 despite it has 3 cylinders only, but now I understand all thank you for your explanation, we need more teachers like you because the explanation is easy to understand ❤
I wondered if anybody would mention the K75. I had a few and was surprised to learn that the K100 didn't have a balance shaft but the smaller engine did. Took me years to find out why. Also had three XS650, there are videos on youtube with this engine featuring a 270 degree crank, sounds cool!
I was waiting till end of video to tell you about laverda jota but you got it 👍 however, no need for cross plane i4 in a car, non equal length headers kinda do the same for sound. Awesome content again. Love the engineering side of things. Further in depth the better 👌
Another superb explanation - and I'm very pleased to see you included the brutal Jota 180 in there, making the video instantly 200% better (subjectively, of course!) Great!!
I've had 5 Triumph triple motorcycles and two triple Suzuki cars and have loved every one, thanks to your excellent explanation, I now now why. I do really enjoy your insight into motor engineering principles and execution. Great presentations, so well done.
Great video! These engines are very mis understood. However, there is characteristic I think you didn't gave enough prase. You did briefly touch on it, but as an owner of two triumph 3 cylinder bikes, I feel it wasn't represented enough. The power curves are incredible. The ability to have such low rpm power and high rpm power is a great combination for a rider. Usually you trade one for the other, but these engines are so useful and fun because of this. Having to choose a low-end or high-end power band can seem fun, but over time impractical nature feels like a unseasonable limitation. The problem is, until you spend a reasonable amount time on a triple, this is hard to fathom. That being said, this video was incredible! 👍
1:39 Now if we take a circle, which is obviously 360 degrees, and divide that circle into three equal parts, we'll see that it turns into a Mercedes logo.

Cool video. This makes me think of the 2.9L F154 V6 in the Alfa Romeo Giulia/Stelvio Quadrifoglio. I believe the firing order in that guy is 120-60-120-60-120-60. The sounds is astoundingly unique. Audi/Porsche have a 2.9L V6 as well, but they utilize offset journals to accommodate an even firing order. Lower RPM and nowhere near as fun to listen to.
Very good explanation of the different character of the two major crank configurations in triples. Extra points for including a brief comment about the old Laverda flat-plane triple.
Triumph and BSA developed the 750cc triple cylinder engine with 120 degree cranks in the 1960's as the Trident and Rocket lll and they were lovely engines bearing in mind the state-of-the-art in those days. The engines ran in perfect primary balance with plenty of torque but a unique sound when pushed hard. I owned a Triumph T150V Trident for more than 30 years - blew it up in '78, kept it as a basket-case then rebuilt it in about 2005 and regret getting rid of it now. I loved that bike, but the roads are so much more manic nowdays and I doubt I would have survived to today if I had kept it 😬
I'm the proud (original) owner of a 2014 FZ-09, and I have to say, it's the smoothest motor I've ever ridden. The dyno chart is pretty much a 45 degree straight line. There is not a flat spot anywhere in the rev range and the spread is amazing.
Been on bikes for many years. I have old parallel twin british bikes, old british wankels, and some new Triumph stuff. In my humble opinion the inline 120° 3 is the best of all when you need a awesome otto-engine. You lack a tiny bit of high rev power, but you got all the torque from down low ;). Well me being a wankel-wanker I will all day love the 120° 3-pots 😎 The old Laverda was called 2 up 1 down ).
Thanks for gifting us your talent of teaching us something so complicated that you made is so simple that anyone with the appetite to learn engine function to a deep level can just see you videos to get there 🙏. Thanks 🙏
I had no idea the gap between power strokes was significant to traction! Makes me wonder how this affects EVs with their smooth, constant power delivery.
I know it is a late reply but any motor with 4 or more cylinders also has no gap in power so they would act similarly. Main thing with EVs is the instant 100% torque at any RPM
@@dankmemedog that makes sense, but the question still remains, as 4+ cylinder motorcycles are never used in offroad applications. Triumph are really the only ones making adventure bikes (dual purpose) with 3 cylinders, the rest are 2, and dedicated offroad dirt bikes are all singles. Probably just a miniscule part of the equation, but curious nonetheless.
electric motors actually have better traction control compared to Piston engines because the computer controlling it can monitor each and every power pulse. A three phase induction motor has three pulses every rotation. A 4 stroke single cylinder has one pulse every 2 rotations, so an electric motor can modulate power 6 times as frequently. There's nothing stopping someone from programming the motor to mimic a 4 stroke single, or going even further. This is further amplified by the fact electric motors are geared shorter compared to Internal Combustion Engines because they can rev higher.
Interesting fact about Triumph/BSA triple was the crankshaft was forged flat, reheated and the two outer crank throws were each twisted 120° either direction around the centre cylinder. It was a neat solution that worked perfectly without any problems,it was so successful that it was copied by Hinckley when the triples were relaunched.
I'm a big fan of these videos illustrating, by sight and sound, the difference throughout the rev range. I'll admit to being nearly obsessed over the different crank configurations of parallel twins.
The combination of excellent graphics and complete clarity of explanation make your channel a must see for anyone interested in combustion engine design and practice. You have a gift for exposition. Thank you, d4a.
Thanks a lot! Today i learned something about my Tiger 955i and recognized it right away in the sequence with sound simulation. Great explanation as well!
I have a 24 XSR900. I chose it specifically for the CP3 engine. They are my favorite by far. Very torquey and fun all the time and they have the best sound with a cool high and low mix.
This is a cool video especially since I own both an MT-09 with the CP-3 and a Tiger 900 with the T-Plane triple. Both are awesome engines but good God do I love that Yamaha
Brilliant video. Something aside from firing interval and balance is the inertial effect of the constantly oscillating piston on the rotation of the crank. Don't claim to be an expert on this but I believe that a 90 degree crank pin spacing cancels this out while 180 spacing reinforces it. I have not seen any of your videos refer to this. Could be one reason the cross plane engine is so good for racing because the crank rotation is smoother and better for tire wear and traction.
You're speaking of secondary balance. Watch the graph and the 90 vs 180 crank offset will immediately make sense. Watch the linked video to learn why it actually happens.
I have just read a book on the history of Kawasaki. Of interest is that when using h2r engines in sidecar racing some teams built their crankshafts so that all three cylinders fired together. An early adaptation of a big bang engine. Wonder what it sounded like!!
Excellent as always!! I presently own a Triumph Speed Triple & traded a Yamaha MT09 for it. Having the opportunity for extensive comparison of the two I honestly noticed little difference in vibration character. Both engines are wonderful!
Great explanations. Now all we need is for motorcycle reviewers to be honest about the vibration result. Side considerations are engine noise, not exhaust noise, and RPM at highway speeds/gearing. An example would be the BMW K100LT I used to own. It was comfortable at only one speed, 73mph, and buzzed everywhere else.
In 1978, I bought a Laverda 1200 Mirage brand new, it definitely had a 180 degree crankshaft. Unusually, it was pressed together, with ball bearings for the main bearings and needle bearings for the big ends, like a 2-stroke. It was, in fact, quite smooth. I thought that it was smoother than my friend’s Kawasaki Z1, which had an annoying tingle, at high rpm. The Laverda had an uneven exhaust note, a bit like a 4 cylinder engine, firing only on 3 cylinders. I installed an open 3=>1 open racing pipe which could be heard from about 2 miles away . . . . it was a beast! In 1981, Laverda switched to a 120 degree crankshaft, which made a smoother sound, but lost the character of the original 180 crankshaft and it vibrated at high rpm.
This video made me recall my first Honda twin. It had the same firing order as my dad's John Deere, 180 & 540 degrees as opposed to Triumph twins being 360 & 360 degrees. On the Honda & John Deere the crankpins were 180 degrees apart while on the Triumph both pistons were at TDC at the same time. This gave the Honda better balance while the Triumph offered a smoother power flow. As for the John Deere balance wouldn't have been a concern at 900rpm.
Awesome video. Thanks for putting this out. This is great. I love the inline twin with 270 deg crank, however; I really want to try the T-crank triples.
Very cool video. Normally stuff like this just goes well over my head, like even if you explained it like I'm 5 I probably still wouldn't get it, and yet I was able to comprehend most of this. I think the visual stuff helped a lot.
I have owned a Honda XL500s and much later on a Triumph 900 triple. Both fantastic bikes but totally different. The Honda was pure grunt from the first rev, no back tyer made it past 700 km. The Trump was smooth as and it had a gradually rising torque line, a pleasure to ride.
Thanks so much for sharing another awesome video! The color coding was especially helpful for clarity and quick understanding of concept. Nicely done, and very informative!

I'm an engineer, and you gave me some insight into the finer details of a 3 cylinder engineer, plus a Triumph fan & rider.. 👍
I have a Tiger 900 and when I knew my motorcycle has such a strange engine configuration I thought this was stupid. Now I do not think it is stupid anymore. Thank you. Keep beeing probably the best channel on mechanical engineering ever.
Me too. The vibrations have a sense of character, but also frustrating. The 2025 model has better vibration control on the handlebars and seat.
The heat from the radiator fans is bad in summer, I put a heat shield over them.
@@sliglusamelius8578 as a 2024 tiger owner. Could you give me a product what ur using as heatshield? :)
My Daytona 675r might have some fuelling issues atm but the sound when she's right is just the most beautiful thing. Knowing a bit more about it from this makes it even more special. Nothing like a triumph triple
Thats a nice bike, I would have gotten one if the riding position wasn’t so agressive
Totally with you there! I've got a 2009 Street Triple and I love the engine note. When I see other triple's I know it before I even see it just by the sound.
The Petronas FP1 did use a 180 degree flat plane crank in some of their race bikes during their final season in WSBK. It was never homologated and yes it would have sounded different to the 120 degree but they were desperate for power during that last season and the other teams knew it would never be a title contender due to being a smaller capacity engine compared to the 1000cc 4 cylinder bikes being used after the change from 750cc 4 cylinder to 1000cc 4 cylinder. The petronas FP1 was never going to be a bike that got sold even though rumours that the full homologation numbers were not met, Petronas did actually build the number of bikes needed to homologate them for racing even though they never passed homologation for the road at the time. Riccardo engineering did run a number of them to try to homologate them but due to over heating of the rear facing cylinder heads and the issues the race bikes had with cylinders becoming oval due to massive heat behind the cylinders and colder air on the forward facing intake side Petronas decided it was too much of a risk for them to sell due to the liability claims they could face.. But they did use flat plane cranks in a number of bikes. How do I know?? I worked for the company that made them..
Copy and paste right off the www verbatim ...LOL Smiths tried that in 2014 IOMT Johnson's Daytona 675 ..he won...but that was a one-off engine which really had no performance advantage except for the sound LOL
@@carlmayer691 co[y and paste off WWW? The 180 degree flat plane crank has not been mentioned on the internet and was never spoken about even though other teams will have known from the sound. But the 180 degree crank was quite a bit lighter than the 120 degree cranks. I know because I worked at the company that made them. The 120 degree cranks would allow the bike to rev to about 13,000 rpm but in the end the lighter 180 degree crank engines were supposedly going to 15,000rpm and as they plugged a fresh engine in after every race the extra loads on the pistons and rods was a risk they were willing to take. So between race one and race two later that same day the engine would have been swapped. The FP1 had bigger issues than the crank, it was only 900cc not the 1000cc like the others and the reversed head was distorting the cylinders as the back of the engine was so hot with no air supply to remove the heat and the colder intake at the front would have a disparity from front to back that was enough to distort the engine during racing conditions. The flames when going into corners was them dumping extra fuel (and some oil getting past the rings) trying to cool the engine every chance they had.
You're right.
Just when you thought 3-cylinder engines were really straightforward :D I kinda envy early engine guys when they started experimenting with all these geometries!
And now I have a craving for some CP Chocolate Pudding :D
I often imagine the early days and all the experimenting! Must have been an incredibly fun time.

Thank you for this explanation.
As an owner of both a Tiger 1200 and Street Triple, I was not really understanding the difference between these two engines, particularly where off-road traction is concerned.
Now I see how the T-plane assists traction, and also it’s distinctive sound.
The 'flat plane', 180° Laverda triple was known for being better able to withstand race tuning than the 120°, a lot of racers continued using it long after the introduction of the latter. I think this was because the pressed-up crank was less prone to twisting its crank pins/webs out of alignment at high RPM and outputs with the 180° layout.
In the early 80s I rode a 1200 Mirage TS which had a 180 degree crank. The vibration was terrible. It was also very heavy at 250kgs. The original Jota was also 180 but I test drove a newly released 120 which was fast and smooth. I didn’t buy it because I wanted a tourer not a cafe racer. The Mirage with a120 crank would have been a great motorcycle.
.
@@selbub I can imagine what the 1200 must be like, in theory at least as much vibration as a big (400) single, probably worse in fact. The RGS with its polypropylene bodywork and 120° crank was my dream bike back in the day (one of the most expensive bikes on sale at the time), might have suited your needs by the sound of it. Laverda always made their engines heavy (the twins were just as chunky), I think the idea may have been to 'mass damp' the vibration (which didn't really work). People convert the twins to 270° with some success.
If the middle of these 3 pistons had have doubled in weight, it would have balanced out the oscillating masses of his lighter brothers.
@@selbub Properly tuned smooth as silk
I will have to admit that a derestricted Rocket3 has the most glorious exhaust note.
I often hear them going past my place and they are the one bike I can instantly identify by sound .
They sound surprisingly like a Rolls Royce Merlin. I know this because I once had a spitfire pass over my house at an altitude of about 30 metres.
bro.. its a 2.5 liter engine. what do you expect
@@TheRealBhuado capacity has little to do with it
@@paulg3336 displacement is the ONLY reason the sound is deep and throbbing. have you heard a 400 sound deep? no. because the displacement is what makes the sound rich
@@TheRealBhuado Vintage 250 and 350 singles wit megaphones
There's something about the exhaust note of engines with numbers of cylinders divisible by 3--3s, 6es, and 12s. There's kind of a 5th overtone in there that's lacking in twins and fours. It may have to do with the fact that there's a 3:2 ratio between the stroke and the firing interval--like 180/120 which in harmonics is a 5th overtone. It's a beautiful sound, I think.
I own a Triumph, I've always liked the different engine sound and the low down grip. I just didn't know why it was happening. My day is better for knowing. Thank you. 😊
Man, this is becoming the engine balance channel
Best teacher on youtube, teaching me about things i didn't even think i needed to know
Just commented after the brake video.
I would absolutely love a master cylinder video to help understand how you can actually brake faster (and almost more importantly, more consistently). Some guys deleted the booster but install a larger master cylinder. Chasebays make great kits, especially their dual piston master cylinder with a 6:1 pedal ratio.
Thanks for these video,
Mark
The smaller the bore diameter the higher the braking force, however the smaller the bore diameter the less fluid it can move within the same stroke. so when you remove the booster, and swap to dual masters, they are usually smaller diameter than the single boosted master. Some people like the feeling of stiffer pedal and go up in bore size regardless if its boosted or not, however it requires more pedal force to get the same clamp force at the caliper. you can offset that a bit by increasing the pedal ratio (if space constraints allow, and pedal wont be too high)
You cannot brake harder than the tyre grip break point that all well maintained brakes without abs should easily obtain. I have never been on a motorcycle that more than two fingers are needed , stiff calipers, air , and pad/disc contamination are behind all crap braking imao.
@@MyKharli that’s true, but I don’t think that’s the question. I think it’s more about braking feel and that will be ABS independent. It’s ultimately a hydraulic system, so changing pistons on either side should affect the mechanical advantage, same as changing the fulcrum on a level.
Ran Lotus and AC without boosters. No prob on light cars with single piston calipers and small discs. Double the brake tube diameter and add heatsinks on the steel lines. 3x the amount of fluid scavenges heat from the pads very quickly. Avoid rubber hoses.
your teaching ability deserves MONEY...
Oh man! I consider myself as a very capable technician, but I feel that I'm running to follow you.
You speak really fast, and the figures in the background distract me, and I paused the video often in order to understand.

Tiger 900 2024 owner here! I love the versatility of the engine, torque at low-end and all the power to make overtakes, even with a passenger and luggage. I love this engine. If you put it in sport the sound changes and it's glorious close to the redline!
Does it vibrate? Yes and no, less than a 2cly more than a "normal" 3cly. Still you can do 8hs rides and have no problems.
Recently comverted triumph 3 fan here. Have had everything else and then on a goof a bought an old speed triple. I loved the engine character and the chasis, though everything else was kind of mediocre and it had no tech at all. Moved up to a 1050 rs which has all the goodies and an even better version of the engine. Eventually I'll go to the new 1200. Triples 4 lyfe.
Bro I was literally looking everywhere for a in-depth video on the Inline 3, your timing is perfect
Now I know why the Triumph triple sounds like it does. I do love it. Excellent work, as always.
So glad you remembered the Early Laverda Jota Engine . Idea was good . Vibes like a 350 single was their idea.
Great presentation 👍👍
I love my 2017 3-cylinder 815cc John Deere Gator🇺🇲.
I road raced a 1975 Laverda 1000-3🇮🇹 way back when. ✌️

Your animations and explanations are better than anything we can get from the manufacturers by a mile! It's funny how the trend in automobiles seems to be the opposite... Barely can find a good picture of their motors, let alone mechanical details, images, and thorough explanations. We have to rely on third parties for that... And in that realm your videos are superior... Please keep creating them!
Wow, came to learn about the difference between I3 engines and learned a concept about motorcycle traction I have never heard anyone explain before. Great video!
Hi amazing video like always. I'm nothing of an engineer, I'm a Seaman at Bridge, but absolutely passionate about engines and following this channel for years !
I have GR-Yaris inline 3 cylinder 1.6 liter engine, and have a Triumph Sprint inline 3 cylinder 955i. Now I understand why they both sound so different no matter which exhaust ! Thanks again for this video !.
Great explanation of the differences between the design of these triples. Surprised our host didn't include a pic of the Triumph Trident from the 70s. Must point out a small mistake in his commentary, however, that occurs around 9:03. In talking about imbalances he says, "Secondary balances become very noticeable and don't require a balancing shaft." What he meant is negligible, not noticeable. As always, great presentation, information, and graphics.
Fantastic explanation of the balance challenges and the pros and cons with the different configurations. Regarding the Laverda triple, I have to point out that all the production 3 cylinder (3C) Laverdas had the 180 engine from the very early ´70s up until the 120 crank made it's appearance at around 1982. The Jota was simply one of the numerous models produced. The reason for going to 120 was not vibration but engine noise for the regulators. A 180 motor in the rubber mountings of the 120 frame is a vibration fix. The character of the 180s has ensured that there are many who have never strayed, they are a unique experience and that is a major factor for a great many motorcyclists.
Loved my Trumpy 1050cc 3 cylinders engines. Add a race pipe and tune and those were awesome sounding flame throwers :)
Perfect analogy used to describe a rocking couple. You're a great teacher
This guy is a natural. Well done!
I am a proud owner of a 2022 Tiger 900GT and i will say im in love with my triple engine. When i saw this video, i had to watch :) The engine really does have a split personality, a great sound and is such an enjoyable motorcycle.
Triumph does this for ages and does it perfect. Great bikes with great felling and power on the road..
Oh wow so far the best explanation of motorcycle engineering! I used to be confused about why Yamaha called it CP3 while it sounds too "smooth" for crossplane unlike CP4 that sounds more deep and rumbly, and the other side Triumph Tiger 900 sounds deep and rumbly like CP4 despite it has 3 cylinders only, but now I understand all thank you for your explanation, we need more teachers like you because the explanation is easy to understand ❤
You get extra points for caring about the clarity of your presentation.
Thx for the explanation!. I have a 120 crank BMW K75s with bal shaft and an old Jota. Just really enjoy triples!
I wondered if anybody would mention the K75. I had a few and was surprised to learn that the K100 didn't have a balance shaft but the smaller engine did. Took me years to find out why.
Also had three XS650, there are videos on youtube with this engine featuring a 270 degree crank, sounds cool!
Those sound examples, magnificent, can hear the rithm of my own Triumph.
I was waiting till end of video to tell you about laverda jota but you got it 👍 however, no need for cross plane i4 in a car, non equal length headers kinda do the same for sound. Awesome content again. Love the engineering side of things. Further in depth the better 👌
Forget the sound, I want the feeling of the CP engine ! Flat crank engines feel like an OFF/ON switch unless it's a V8.
When I started watching your contents, I was in school. Now I am an Automotive engineering student.
Most comprehensive explanation ever!
yamaha CP3 is a gem
Okay, that gave my brain workout after my morning run gave me a body workout. So much information compressed into so little time. Kudos!
Another superb explanation - and I'm very pleased to see you included the brutal Jota 180 in there, making the video instantly 200% better (subjectively, of course!) Great!!
I was lucky enough to have owned two Laverda Jotas both with the ‘180 crank. Incredible sound . Now enjoying Triumph’s T-Plane 👍
i loved the Chocolate Pudding explanation -- this is the mastery of math-logic
I've had 5 Triumph triple motorcycles and two triple Suzuki cars and have loved every one, thanks to your excellent explanation, I now now why. I do really enjoy your insight into motor engineering principles and execution. Great presentations, so well done.
Great video! These engines are very mis understood. However, there is characteristic I think you didn't gave enough prase. You did briefly touch on it, but as an owner of two triumph 3 cylinder bikes, I feel it wasn't represented enough. The power curves are incredible. The ability to have such low rpm power and high rpm power is a great combination for a rider. Usually you trade one for the other, but these engines are so useful and fun because of this. Having to choose a low-end or high-end power band can seem fun, but over time impractical nature feels like a unseasonable limitation. The problem is, until you spend a reasonable amount time on a triple, this is hard to fathom.
That being said, this video was incredible! 👍
1:39 Now if we take a circle, which is obviously 360 degrees, and divide that circle into three equal parts, we'll see that it turns into a Mercedes logo.

Definitely miss my street triple R. Phenomenal bike
I definitely need a coffee after this engineering class ☕
I love your videos. That's all I got man. You're criminally underviewed.
Cool video. This makes me think of the 2.9L F154 V6 in the Alfa Romeo Giulia/Stelvio Quadrifoglio. I believe the firing order in that guy is 120-60-120-60-120-60. The sounds is astoundingly unique. Audi/Porsche have a 2.9L V6 as well, but they utilize offset journals to accommodate an even firing order. Lower RPM and nowhere near as fun to listen to.
Very good explanation of the different character of the two major crank configurations in triples. Extra points for including a brief comment about the old Laverda flat-plane triple.
Triumph and BSA developed the 750cc triple cylinder engine with 120 degree cranks in the 1960's as the Trident and Rocket lll and they were lovely engines bearing in mind the state-of-the-art in those days. The engines ran in perfect primary balance with plenty of torque but a unique sound when pushed hard.
I owned a Triumph T150V Trident for more than 30 years - blew it up in '78, kept it as a basket-case then rebuilt it in about 2005 and regret getting rid of it now. I loved that bike, but the roads are so much more manic nowdays and I doubt I would have survived to today if I had kept it 😬
I'm the proud (original) owner of a 2014 FZ-09, and I have to say, it's the smoothest motor I've ever ridden. The dyno chart is pretty much a 45 degree straight line. There is not a flat spot anywhere in the rev range and the spread is amazing.
Been on bikes for many years. I have old parallel twin british bikes, old british wankels, and some new Triumph stuff.
In my humble opinion the inline 120° 3 is the best of all when you need a awesome otto-engine. You lack a tiny bit of high rev power, but you got all the torque from down low ;). Well me being a wankel-wanker I will all day love the 120° 3-pots 😎
The old Laverda was called 2 up 1 down ).
BSA Rocket 3 is a derserving winner of the accolade, Triple Trouble. BUT, when everything is right, not many bikes sound quite as good!
Excellent and informative. Love the firing graphic.
The best teacher on the youtube there is. Make my sundays perfect Who says sundayschool is boring.
Thanks for gifting us your talent of teaching us something so complicated that you made is so simple that anyone with the appetite to learn engine function to a deep level can just see you videos to get there 🙏. Thanks 🙏
I had no idea the gap between power strokes was significant to traction! Makes me wonder how this affects EVs with their smooth, constant power delivery.
I know it is a late reply but any motor with 4 or more cylinders also has no gap in power so they would act similarly. Main thing with EVs is the instant 100% torque at any RPM
@@dankmemedog that makes sense, but the question still remains, as 4+ cylinder motorcycles are never used in offroad applications. Triumph are really the only ones making adventure bikes (dual purpose) with 3 cylinders, the rest are 2, and dedicated offroad dirt bikes are all singles. Probably just a miniscule part of the equation, but curious nonetheless.
electric motors actually have better traction control compared to Piston engines because the computer controlling it can monitor each and every power pulse. A three phase induction motor has three pulses every rotation. A 4 stroke single cylinder has one pulse every 2 rotations, so an electric motor can modulate power 6 times as frequently. There's nothing stopping someone from programming the motor to mimic a 4 stroke single, or going even further. This is further amplified by the fact electric motors are geared shorter compared to Internal Combustion Engines because they can rev higher.
@@nightcoremetal2518 I hadn't thought of the phases of an electric motor! Great insight.
Read up on the Big Bang engines used in Moto GP
Interesting fact about Triumph/BSA triple was the crankshaft was forged flat, reheated and the two outer crank throws were each twisted 120° either direction around the centre cylinder. It was a neat solution that worked perfectly without any problems,it was so successful that it was copied by Hinckley when the triples were relaunched.
Excellent job explaining the engineering behind the 3 cylinder engine.
I'm a big fan of these videos illustrating, by sight and sound, the difference throughout the rev range. I'll admit to being nearly obsessed over the different crank configurations of parallel twins.
I am in love of this explanations...you deserve a medal 💪
The combination of excellent graphics and complete clarity of explanation make your channel a must see for anyone interested in combustion engine design and practice. You have a gift for exposition. Thank you, d4a.
Thanks a lot! Today i learned something about my Tiger 955i and recognized it right away in the sequence with sound simulation. Great explanation as well!
I have a 24 XSR900. I chose it specifically for the CP3 engine. They are my favorite by far. Very torquey and fun all the time and they have the best sound with a cool high and low mix.
This is a cool video especially since I own both an MT-09 with the CP-3 and a Tiger 900 with the T-Plane triple. Both are awesome engines but good God do I love that Yamaha
Brilliant video. Something aside from firing interval and balance is the inertial effect of the constantly oscillating piston on the rotation of the crank. Don't claim to be an expert on this but I believe that a 90 degree crank pin spacing cancels this out while 180 spacing reinforces it. I have not seen any of your videos refer to this. Could be one reason the cross plane engine is so good for racing because the crank rotation is smoother and better for tire wear and traction.
You're speaking of secondary balance. Watch the graph and the 90 vs 180 crank offset will immediately make sense. Watch the linked video to learn why it actually happens.
Awesome video man. You are a very talented engineer and have a great way of explaining complicated concepts.
All you videos: Thanks for in depth descriptions. Excellent graphic animations too.
Excellent, excellent video! Makes it so easy to understand - well done
I have just read a book on the history of Kawasaki. Of interest is that when using h2r engines in sidecar racing some teams built their crankshafts so that all three cylinders fired together. An early adaptation of a big bang engine. Wonder what it sounded like!!
Excellent as always!!
I presently own a Triumph Speed Triple & traded a Yamaha MT09 for it. Having the opportunity for extensive comparison of the two I honestly noticed little difference in vibration character. Both engines are wonderful!
Great explanations. Now all we need is for motorcycle reviewers to be honest about the vibration result. Side considerations are engine noise, not exhaust noise, and RPM at highway speeds/gearing. An example would be the BMW K100LT I used to own. It was comfortable at only one speed, 73mph, and buzzed everywhere else.
In 1978, I bought a Laverda 1200 Mirage brand new, it definitely had a 180 degree crankshaft.
Unusually, it was pressed together, with ball bearings for the main bearings and needle bearings for the big ends, like a 2-stroke.
It was, in fact, quite smooth.
I thought that it was smoother than my friend’s Kawasaki Z1, which had an annoying tingle, at high rpm.
The Laverda had an uneven exhaust note, a bit like a 4 cylinder engine, firing only on 3 cylinders.
I installed an open 3=>1 open racing pipe which could be heard from about 2 miles away . . . . it was a beast!
In 1981, Laverda switched to a 120 degree crankshaft, which made a smoother sound, but lost the character of the original 180 crankshaft and it vibrated at high rpm.
This was a great video with fantastic animation and technical detail. Thanks for sharing your knowledge!
3 cylinders engines details I was looking for, thank you, excellent video!
Thank you, you put together an amazing explanation of the 3 cylinder engines. I ride a triumph sprint 1050 and love the engine.👍
Is the 1050 a T-plane?
@@fredrosse no it isn’t. I believe triumph came out with that firing order in 2019
This video made me recall my first Honda twin. It had the same firing order as my dad's John Deere, 180 & 540 degrees as opposed to Triumph twins being 360 & 360 degrees. On the Honda & John Deere the crankpins were 180 degrees apart while on the Triumph both pistons were at TDC at the same time. This gave the Honda better balance while the Triumph offered a smoother power flow. As for the John Deere balance wouldn't have been a concern at 900rpm.
Nice example! Here's a little video on twins in case you're interested: th-cam.com/video/a9ZFZABaLbg/w-d-xo.html
The Deeres do shake. The only reason balance isn't much of an issue is that they're so heavy that engine balance isn't that significant.
Awesome video. Thanks for putting this out. This is great. I love the inline twin with 270 deg crank, however; I really want to try the T-crank triples.
Just some praise for the algorithm: Hands down the best channel about this topic! 🤗🤩
Very cool video. Normally stuff like this just goes well over my head, like even if you explained it like I'm 5 I probably still wouldn't get it, and yet I was able to comprehend most of this. I think the visual stuff helped a lot.
Very excellent explanation. I learned things I didn't even know I didn't know today.
I have owned a Honda XL500s and much later on a Triumph 900 triple. Both fantastic bikes but totally different. The Honda was pure grunt from the first rev, no back tyer made it past 700 km. The Trump was smooth as and it had a gradually rising torque line, a pleasure to ride.
Yes, I remember the Jota. Was a wonderful torquey bike and always wondered what killed it
Great video man, as always!
Just happy to see you showing stuff on these motors. Love my Tiger
