The fact that these scooters are eubiquitous and very common does not take away from how absolutely brilliant this engineering is.

One of the best explanations bout scooter CVTs so far.

Wow, that’s actually a good explanation. Especially liked the centrifugal clutch part, always wondered how some go-karts can keep engines running at low speeds.

Wow, ive always wondered how scooters ran without gears.

Snowmobiles and industrial machines have used this system for decades. Nice animation.

I absolutely LOVE this women’s voice and could listen to her voice 24/7 365! Just soothing and relaxing.

Very nicely done. I have been maintaining my own scooters for a few years now, and was familiar with most of the theory/physics behind the system, but I was happy to learn a little more here. This video is a fantastic resource. If I were teaching English to mechanics or engineering students, this would certainly be on my go-to list. Thank you.

I have a scooter and was watching this in class then on my way back home my belt went "pop" 🙂

This was by far, the best explanation I have ever seen on anything in the few years I've been involved with 2-strokes specifically.

I am not an engineer but after watching this video I am feeling like becoming one. Beautiful video.

Keep these animation / explanation vids coming. These are just awesome to show people HOW things work instead of trying to explain it to them! Thank you TM.

Really one of the most genius inventions in transportation. This is the entire powertrain right here. Attach that wheel to somthing, and you've got a working vehicle. Cheap to produce, simple to maintain and it works well.

Excellent video. Great illustration of the CVT. I love it when someone can show and tell you how something works in a few short minutes with such clarity. Thank you very much.

I just found this channel and I absolutely love your videos. I’ve already watched most of them and am binge watching the rest. As a biker and aspiring mechanical engineer I find them very interesting and informative. Just wanted to say, thanks and keep up the great work.

I understood how the CVT worked in scooters before this video, but the detail and clarity helped fill a few gaps such as the centrifugal clutch being located on the rear pulley. I always thought it was on the front..Makes sense..

you guys who makes these animation vids are the real mvp. beginner mechanics wannabe like me truly appreciate it

This channel does a great job for humanity. This kind of content is very beneficial for the society. I would like to thank the producers and supporters.

That’s some beautiful engineering.

The best possible way to explain the working of any systems, excellent demonstrations.

Thanks for the amazing animation and voice over to make us understand the concept of CVT!! The best video I have seen on CVT!!!

Great animation. I was always wondering how scooters work without manual gears. Turns out it is another genius feat of engineering

Engineering behind this awesome, it is hard to believe how the things calculated to obtain this, but all I can say it is incredible

Best explanation. only takes 3 and a half minute. while other videos took an hour.

UKposts is showing me what I really actually want to watch I'm very thankful

Thank you for creating such an informative and entertaining video on UKposts. Your hard work and dedication to the topic really shines through and I appreciate the effort you put into it. Keep up the great content!

Very handy and useful information as this process is always a bit complicated to imagine in it's whole even for experienced riders and mechanics since there are so many parts envolved in it 🧐🤨🙂.Big thanks all the way from Portuga🇵🇹 for the making of such video!

I wish this channel uploads more often. Really great channel, and fun to learn and watch.

Thanks for the very detailed info on CVT! Even a pro mechanic would fail to make us understand this clear!

This is an absolute information to understand CVT. Thank you very much and keep making videos like this

Simplest and most detailed I have ever watch about Cvt. Good Job! 👍👍👍👍👍

How great is this channel! And how epic are the people who thought of CVT using 2 conical plates!

Really neat to see as I just had to learn all about this recently. Not long ago I upgraded my wife's scooter with a new variator and slightly heavier rollers, which ultimately gave it some more top end speed (From about 36 mph top speed up to 41-42). Quick operation and really woke that little scooter up

Came here for scooter engineering, but got ASMR instead

I wish this yt channel gain more subs! Thanks for all the wonderful animations and content.

When I was little, my dad built a go-kart/yard-kart for my brother and I. It used this same system with a 5hp Briggs&Stratton motor. I had a general idea of how it worked, but this was interesting. I’m now an engineer, but I work with robotics and automation.

That gear train seems very important as to let the cvt and the clutch work at high rpm where the centrifugal force can act and have a low torque to prevent friction - all tagnks to the speed reduction ratio

This was a great explanation of what goes on in the variator and how the clutch works, but they left out what controls the movement of the belt up and down the cones on the clutch/driven side. It looks to me like that is simply the fact that the belt is a fixed length, and as the diameter of the drive pully expands the belt tightens between the pullies, forcing the belt down further between the cones of the driven pully, forcing them apart and compressing that yellow spring you see at 2:30. It might be obvious to most people but it wasn't to me at first and I wish they would have at least mentioned it. Overall though great explanation thank you!

Thanks for a great vid. I had a reasonable understanding of the system but you showed me how the clutch worked & also the final drive from the driven pulley to the rear wheel. I owned motorbikes for 14 years but changed to scooters in 2019 as I LOVE the ingenuity of their CVT system & their practicality far exceeds that of motorbikes for regular 'daily driving'. 👍

Make more videos like this👌your explanation with the perfect animation clears that particular concept

Clear and concise... Great video

This is getting out of hand now. Another day where just a thought in my head and the related video pops up in my recommendations. 🥺

This is by far the best explanation video in the internet.

Thank you for this! I know it is a small detail, but having a female narrator means everything to me. Thank you!

I used to tear this system down since 15YO and it fun playing with Yamaha or Honda CVT ☺️

this reminds me of the variable valve timing on Suzuki´s GSX-R1000

Amazing video...I was thinking for long to search how gearless enzine works and today I saw the video in recommendation..UKposts is reading my mind.

These videos are awesome keep them coming... They are so easily understood and demystify the subject of interest extremely they make it so much fun to learn.

Such a big help for me as a partsman on a motorcycle shop👌👌👌

This technology is thanks to the endeavours of Rokon motorcycles who were the first to put it on their motocross machines back in the 1970s. At the time most technical experts were very sceptical of their practicability.

Best animation demonstration I ever had. Best explanation.

This information were absolutely magnificent as well as knowledgeable .. wow!!

Wow, all along i was thinking scooters has automatic gear shifting system.

Very nice explanation indeed!

For a long time I’m searching for this video. Thanks for the information

Thank you for this informative video. I learned something today (2 years later).

So the belts are not engaged by their teeth but by friction against the conical parts? Could someone please clarify? Thanks

The real beauty of this system, when you think about it, isn't just the functional result but the sheer simplicity of it. There are so few manufactured parts compared to a conventional motorbike - I finally understand why scooters can be produced so cheaply. They must be a doddle to service too (other than belt removal and installation, which is probably a right laugh).

thank you this is the clearest explanations I've found about scooter's cvt

When the shortest video are wealthy it looks like this one you don't have to spend much time to gain the information thank you

Nowadays, this tutorial/presentation will be very helpful for those who are owning and driving their #YamahaNMax ( #NMax )...

Small capacity low output engines work best with CVT . Infinet gearing always uses the maximum power available. A gear box is nowhere near as power efficient. That's why at the lights the scooters leave the Porsches standing up to 30 mph. 12bhp vs 200bhp CVT works. It actually also works well in small engined cars

Nice! I had some vague sense of how this operates, now it's very clear. Should help me figure out why mine isn't doing this!

Such an amazing and simple explanation!!! Thank you so much☺

Pops up on recommendation. Me: Oh how interesting!

As one of the biggest fan of this UKposts page.Can i know How much day's would it take to make one animation video like this. Plz comment

There were small car made in Netherlands (DAF) with twin similar transmission. I have also seen some motorized bicycle with CVT

Amazing, I've recently switched to a Yamaha scooter and its incredibly smooth at all speeds.

This is precisely the principle of the DAF variomatic, invented by them (Hub von Doorne) and first put into production in 1958 on the Dutch DAF 600 car.

Suggestion: I think it would be clearer if you mentioned "High torque vs high speed", instead of contrasting "high torque vs high RPM". I think you're referring to high RPM for the wheel, which translates into high speed. Most people who use the term RPM are normally referring to the engine.

Brilliant explanation.Now i know exactly how it all works!!!thank you!!!

another episode of everything can be learn easily with good animation thank you

UKposts reccomendation AI has become better at finding videos than I do

Scooter shown in the beginning of the video is HONDA DIO (Indian scooter)

Absolutely brilliant

That's incredible and excellent explanation for Scooter CVT

Nothing: UKposts: How a scooter transmission works

How u do complex modeling plz tell

Thank you very much indeed , because in Indonesia, or in here, west java , java island, cvt bike are a lot of unit ,or maybe city of motorcycle with cvt

can you guys make more videos, because I find it very useful for me to understand my scooter more and motorcycles

Great explanation:) but scooters are still a slow piece of crap that should get off the road :| i always feel like running into the stupid things...they are an insult to the word "motor bike"

Wow awesome. So many days i was searching for this answer. Kindly tells us better way to save fuel & increase mileage

Thanks for information videos, I searched it lot and asked to EV showroom but could not get satisfying answer, and now I understand it. Thanks a lot 🙏

With this video , this helping me to knowing the name of cvt part , actualy i dont understand english language . With this video helping me to knowing the englis name all of cvt part . Sorry for my bad english , i learn this video cause i live in Bali and Mechanic is my job, where my costumer average is tourism from Brazil,Australia,Russian . So with this video i can getting an understanding about cvt part .

thanks,very informative video..nice explanation..watching from mindanao,philippines.

I have an Air Blade 150 for about 9 months this video will be helpful

I'm watching this so that I know how my scooter works and thanks for this great video and animation

Amazing explanation !! Great job. Many Tanks

Very good information. .animated in a beautiful manner..Thank u very much

Cool! Now THAT'S a great illustration of how a CVT works👍. My belt snapped on an old piaggio I once had... Very easy to replace. Just keep in mind, those belts don't last forever. But they are cheap and easy to replace. 😊

Thanks for this video my curiosity over other things decreases

Thanks for the great video.. I have noticed a minor error in audio & subs(while the video frames show correct alignment) @01:47 which states "To obtain high RPM, the diameter of the driver pulley decreases and that of driven pulley increases.." which seems to contradict the explanation given before @00:33. I am viewing here after 4.5 million views, my thoughts were that I had heard it wrong... But here I am writing this comment after checking 4-5 times. Thanks again for the great demonstration.

At 1:48 you say : "To obtain high RPM the diameter of the driver pulley decreases and that of the driven pulley increases" That's the opposite. The driver pulley's diameter INCREASES and the driven pulley's diameter DECREASES.

Beautiful and most satisfying explanation... Kudos..

Wow now it's all clear....thanks! 15 years wondering...

Amazing video

Thanks for the youtube tutorial animation. Because of that i even have more knowledge than to teaching my proffesor.

That's brilliant. Well explained. Thank you.

Such a great channel!

By far the best explanation of a cvt
