4:35 Both the disk and the pads are unsprung mass because the suspension acts "above" them, but the disk is also rotational mass, which you go on to explain very well. Easy to make a small terminology mistake with a long script like this. Thank you very much Sylvain, the education you're providing on this channel is AMAZING.
Yes, that would make a good video, but i have to ask Suzuki and Michelin first. MotoGP tires are different from the ones you can buy. They are made specifically for MotoGP bikes
Awesome stuff. I'm a mechanical engineer and I'm racing in Finnish Road Racing Championship as a hobby, and your videos touch both sides of my world. This is maybe the best content I have found related to racing with bikes. I hope you continue these even after the world normalizes after the corona.
Brilliant commentary. You have a gift for explaining complex principles and compartmentalizing them into specific, usable actions. Bravo from Connecticut.
Hey Mr. Guintoli , absolutely loving all your videos and your descriptions and discussions on the various components and issues around motorcycle riding both Moto GP and also the street and regular racing. Thank you very much for your time and efforts in presenting these absolutely fantastic videos. I’m sure like myself there are many thousands of people who are finding these videos absolutely fascinating. Thank you very much.
Can you do videos on engine firing difference (crossplane vs flat plane) pros and cons? As you ride them both, we would love to hear your opinion on that!
Thoroughly enjoying all of your videos. They're extremely informative and its great that you're not secretive about set ups and riding tips like a lot of other racers are
Awesome. Can't believe none of other pro racers thought about doing this. Great work Sylvain keep making more videos. Just for mater of interest would you be interested to do a video comparing the 600cc vs 1000cc bikes on track and how different they are and what comes and pros of each other. Would be nice to see and hear from pro racer.
Hi Sylvian, another idea for future how to video: explain pull/push techniques for countersteering and bike control - do you push/pull with both hands, one hands etc, etc.. thank youuu keep them coming!
Very interesting and informative. Great presentation skills. It's really fantastic that you decided to make this channel and share with us your knowledge. 💪😀👌
These videos are great, thanks for the info. I'd love to hear about MotoGP engine breaking/torque limiting. Do they really open use a diesel style engine brake?
Thanks again for the great content! According to my experience it's not a given characteristic of a driver to be smart and educational AND being fast on a world-class level
Very well explained! As the main advantage is the weight and the good consequences to the handling and acceleration it would be nice to explain more deeply how angular velocity works and the influence of the weight in connection to the wheel. Cheers from Portugal ✌️ Go Oliveira!!🇵🇹
Salut Mr Sylvain, danke shone pour ces explications, avec si j'ai bien tout lu Freud un avantage particulier aux freins carbone qui limitent le poids non suspendu entraînant plus d'agilité au changement d'angle(moins d'effet gyroscopique), moins de résistance à l'accélération...Et j'y crois toujours pas qu'un champion du monde donne son temps à ses supporters autant que toi avec des infos "totales" et super pédagogiques. Merci, Merci, Merci.
I’m really enjoying your videos, they’re both interesting and informative. Could you do a video about rider weight transfer and how you can use this to improve your riding?
I Always get alot from your posts, thank you. Q: could you do a comparison with the latest types of pads for steel brakes? Ie, Double sintered (those very expensive SBS, brembo and alike pads. And Carbon/Ceramic type pads?
Merci Sylvain pour ces vidéos ! Très biens expliquées, intéressantes, j'ai tout regardé dans la même soirée ! Petite question, qu'elles sont les différences entre un WSBK et une moto d'origine ? Qui sont normalement dérivées des motos stocks
Thanks for another very informative video. Just splitting hairs, I would split (duh!) where you use the term "unsprung weight" in two components: the real unsprung weight, which influences suspension action, and the rotating mass, which influences steering input and feedback. But I guess in the end it is the total package which determines the feel and stability in and out of corners, so... never mind :)
Hey Silvian, great video, love your MotoGP insigh! P. S. To clarify: when you talk about the advantages of light carbon disks, you talk about 'unsprung mass' but you meant 'rotational mass'. Unsprung mass is all the mass below the suspension and inticates how much induced force is counteracting against the movement of the suspension. Rotational mass indicates all the rotation masses, which induce tourques, inertia traps and stabilizing forces on the bike.
Correct! Also angular velocity is conditioned by the weight of the brake parts attached to the wheel. For instance, the corner entrance is much easier if the wheel ( with all involved rotational masses) weights less.
@@DuoMotovlog Also the more weight the more the gyroscopic effect. Thanks Sylvain for the very nice and well explained videos! Pity I only noticed now, but I'm watching all of them- catching up ;-)
Sylvain can you tell us, why MotoGP and Endurance Sportbike like in 8 hours race STILL USING Magnesium Wheel ? Why not using Carbon wheel? That's a lot question and debate between biker in community. I hope you can make the answer with another cool video.
amazing video. one question though: why would a rider use the "high mass" 320mm disc over the normal 320? from what i see at 6:50 the pads are not touching the inner part of the disc, so it looks like useless extra weight
WHAT ABOUT 2 STROKE I watch all you videos there so good but much is about how much the engine braking can help but there not much on a 2 stroke supermoto could you do a video on the differences and how you might adjust your riding to suit. Thanks pal keep the videos coming
what do you think about the weight transfer cancel by tapping the rear brake before hitting the front? the bike sits down and lift less when braking harder.
Sylvain does the carbon carbon brakes feel overpowered or is it just enough to do the job . As u have said brakes limiting factor is tyres .Does suspension and different suspension geometry also have a part in braking. Does using rear brakes control overall suspension dive. Or is there a combination which controls dive. Do manufactures try different rim width for improving handling or braking . Aren't LHS brake ( scooter brake) far more superior to use than foot. As for front and rear brake what are your options with respect to brake piston sizing. And how does it work. Don't u think since launch control is spreading its reach to suspension like motocross bike have . Wouldn't it be good to have suspension control during braking ( manually controlled for now ) . To hold the front suspension in a position to turn harder. How do you anchor your body during braking. From foot to hand. Is there any development to combine the front and rear suspension or use hydraulics to control the dive or rebound .
Did you mean that the carbon disks gain more advantage than the carbon pads because of the decrease in rotational inertia? because both the disks and pads qualify as unsprung masses. I think that would more properly account for the improved turn-in sensitivity. What do you think?
Brake disks are both unsprung mass and rotating mass, but when you're talking about acceleration and braking, you mean to say rotating mass. The pads are only unsprung, not rotating. Lower unsprung mass is why it feels better going over bumps.
You keep mentioning "unsprung mass" when describing the disks, but both the disks and the pads are unsprung mass. The beginning of unsprung mass is with the the upper fork tube. Everything attached below that is unsprung mass.I understand you were talking about the increased gyroscopic effect of having a heavier disk as apposed to a light one -- you can turn more quickly, no?
Yes, probably simplified a bit too much on the edit, lighter pads help too being unsprung. The main difference though is the lighter discs as its unsprung rotational mass that has an important effect on inertia
A quand les scoots avec 1disque carbone et un disque acier sur un Tmax(argument commercial pour les kékés ;))! Et pas mal géré la figure d'Oliveira à la découverte des freins carbone, il a peut-être fait un petit pipi, moi j'aurais fait un gros vol! Ce qui est vraiment impressionnant, c'est la rapidité d'évolution de ces systèmes avec un feeling au top après très peu de temps pour faire évoluer le matériel. Quant au tarif, réservé aux MotoGP d'ailleurs les seuls pilotes réellement capables d'utiliser ce matos de dingue, donc je pourrai continuer à cramer mes pads sur mes disques acier (ou fonte? ça existe encore si ça a déjà existé?) Dès que je reviens à la piste. Et as tu des jantes carbone sur ta moto de superbike ?
There’s something political I don’t like about the little French man... being test driver for Valentino Rossi and Brembo's leadership in the industry has it left a bad sign on his mind...
In Sepang 2015, Rossi rode Marquez out wide but did not intend for any contact. Marquez initiated the contact by not going wide or cutting back but instead riding into Rossi. Marquez wanted to crash and even pulled his own front brake lever to make sure he did. Disgraceful. Watch this video from 4:30 onwards to see for yourself th-cam.com/video/sUCLthQG8Ac/w-d-xo.html
@@Anteater23 I have many times... How about you watch the press conference of Malaysia... Listen to when Rossi says marques helping Lorenzo out Even though Marquez stole that win from Lorenzo in Phillip island... If marquez wanted to help Lorenzo beat Rossi why would he steal 5 crucial points in Phillip island with half a lap to go
Sylvain is now in my opinion now the best motorcycle vlogger, advisor on You Tube. Keep it up. Loving every video
content wise for people who know their shit - 10/10
My favorite moment now is when you release a new video!
4:35 Both the disk and the pads are unsprung mass because the suspension acts "above" them, but the disk is also rotational mass, which you go on to explain very well. Easy to make a small terminology mistake with a long script like this. Thank you very much Sylvain, the education you're providing on this channel is AMAZING.
I like Sylvain's riding and track videos but also enjoy sitting in his garden with a Guinness chatting about bike stuff. Great channel thanks.
Nathan Hardcastle and listening to the birds in the background !
Could you please tell us something more about difference between tyres used in MotoGP and standard tires?
Just slicks no different you can buy them .
@@apollomorris9920 They are not 'just slick'. They are MotoGP specific with specialised construction, heat operating ranges & rubber compounds.
Yes, that would make a good video, but i have to ask Suzuki and Michelin first. MotoGP tires are different from the ones you can buy. They are made specifically for MotoGP bikes
@@SylvainGuintoli thank you very much 🙂
This will be a very interesting video!!✌️
I skipped this video initially because i thought it was going to be boring. But it was not, Sylvain you are a natural youtube talent!
Ça va faire 5 ans que j'ai quitté l'école. Mais à chaque vidéo je me pose gentillement et j'écoute les cours du professeur ! Merci Mr Guintoli ;)

Sylvain, I have nothing to dislike. Great presentation. Your English is also much better than most motogp riders. Keep up the good work!
Excellent video Sylvain!!!
Thanks for making it and sharing it with us!!!

Yes but it is still unsprung mass as well as rotational. He made that clear, well to me anyway.
In similar fashion to a lightweight wheel, carbon brakes do indeed save both unsprung and rotational mass.

1:15: Yes! Your brakes don't brake the bike, the tires do. The brakes are "only" transmitting the torque to the wheels

How does the brake fluid deal with the higher temps with the carbon package?? Is it still dot4?
sylvain, are you gonna do a trail breaking video?
I assume on GP bikes the back brakes are still steel given they're not put under the same load as the fronts?
Aaron McGrath
Probably not simply for weight saving.
What's kind on steal breaks are you using name brand and pads?
What about the max G force for steel, small mass carbon, large mass carbon ?
what happen with pecco last year in valencia fp3?
Did you mean that the carbon disks gain more advantage than the carbon pads because of the decrease in rotational inertia? because both the disks and pads qualify as unsprung masses. I think that would more properly account for the improved turn-in sensitivity. What do you think?
That’s right. Both unsprung mass but the big difference is the rotation mass. So wheels and discs (and tire) mass is the main thing here 👍🏻

Hi Sylvain, little off topic but what watch are you wearing in this video?
Peter TAG Carrera
4 guys who didn't get the Suzuki test rider job dislike this video.
Thnks again!
good job
Can I ask if I used often engine break do I damage the engine or not at all.
Not at all. As long as you don’t over rev’ the engine on downshift.
Thank you for the information! are all the riders understand bike mechanic like you or its because you are a tester?
Thanks for giving us a peak at the MotoGP world!! Hope you win Races.. Beat Marquez.. 😁

Thank you for sharing knowledge🙏 I think WSBK should implement carbon brakes since they do so many laps and the brakes would get really hot
確かにセラミックカーボンはコーナー手前まで突っ込んでフルブレーキングできるが、ドライバーの手腕によるだろう。何故ならコーナーが、壁が一気に近づくと体がこわばるからだ。
セラミックカーボンの特長と特性を理解して、メーカーの信頼がないとブレーキをおいしく使用できないからだ。
クローズドコースのタイムならセラミックカーボン、公道ならスチールで良いだろうね笑
Anyone know the intro song ? Lol
