Chassis adjustment and ergonomics: Tech Talk with Simon Crafar

[@rushabhjoshi30]

Thanks MotoGP and Simon for giving these types of episodes 🙌❤️

[@drdesmo8489]

Simon is the best person to take this job with MotoGP ! His passion and knowledge flow from so naturally. We are blessed.

[@markcotter4213]

PLEASE!!!!!! More Simon!! This is gold!

[@srbs73]

+1 Thanks Simon. Really interesting to hear how the teams can adjust the bikes. I hope more MotoGP fans hear about these tech talks as we don’t get into this detail on race weekend coverage 👍

[@RicardoSilva-qp4bb]

@@srbs73 My thoughs exactly. I always find myself wishing more technical info was refered on the TV coverage, both bike wise and riding wise.

[@lachlancrutchfield1916]

Simon Crafar is the best thing that's happened to the MotoGP broadcast for as long as I can remember. Rough start, copped it, and man has be grown into that role, what a legend!

[@HugoNobrega87]

Spot on! He's now just about perfect for the job. You can tell how all the riders and team members feel at ease when interviewed by him. He's also super respectful of everybody. The culmination was last race when Herve said (I'm paraphrasing) "I'm happy to share this moment with you Simon, you're a special guy!"

[@FardeenIrani]

wow, so many adjustments & variables in the chassis alone. May be as a crew chief who has the technical know how he may be able to understand it, but I always wonder as a rider weather they can every pin point and tell the crew that the pitch is too much, or I need the handle bars more out. I guess the communication between the rider and his mechanics are so vital to give the rider a bike that he feels comfortable and confident riding. Thank you Simon without this insight I don't guess many of us would ever be able to know so much. This makes the races even more fun to watch now.

[@wowIloveusernames]

Wow. Motorcycles are amazing. The amount of variables for someone that knows how to take advantage of them is INSANE. I’ve always loved them, but never have had this understanding of them. So intriguing.

[@ranggafahmi8479]

Agreed. I always wonder how so many riders use the same kalex chassis but with much different speed. I just can't accept the argument that talent alone made that difference. Now this video answered it. There's so much variable in chassis setup alone. Not to mention other variables such as electronics and gear ratios.

[@RicardoSilva-qp4bb]

@@ranggafahmi8479 And suspension also - as Simon didn´t even mencion front/rear suspension setup on this video (altough some count suspension as part of the chassis setup). Very interesting concepts for many people indeed. Fascinating.

[@TheAslakVind]

Dear Simon, you are giving us the super inside explanations, that the fans want. In the detailed way, that makes us understand. I understand why a rider/crew chief can get lost. Your way of explaining is second to none. Looking forward to the next Tech Talk!

[@paolopretara6611]

We could have never imagined the kind of work that mechanics do in order to prepare their rider for battle without these tech talk videos. I, like so many, have learnt so much more about motogp and built an even greater appreciation for their work and passion. Please dont stop doing these tech talk videos!

[@randyalakas7260]

This episode is just gold, a lot of my friend said that skill is everything, they just didn't see the bigger pool of this

[@RicardoSilva-qp4bb]

Understanding where you are going I also have to say that bike setup is also a skill set as much as pure ability to ride the tits of a motorcycle. :-) In my opinion.

[@mmates007]

Put Simon on more....he is so good and has great knowlege and is able to explain so I understand it. More Tech talks from Simon please!

[@TheLimhammett]

I used to slate him for speaking too slow but when it comes to these explanations, i appreciate the way he speaks. Simon is gifted as a to speak on these tech talks.

[@jonathanblack3]

Simon, you're doing a great job explaining and showing components and application. Good to witness your continuing enthusiasm. Jonathan (fan)

[@roarkshsha]

What a fascinating subject. Nicely explained. I could listen to Simon, explaining motorcycles, all day.

[@Nomads_Rowing]

Thanks again Simon allowing us mere mortals to get an insight to the dark art that is setup without the usual patronising approach of some feeds 😎

[@pauljoseph8338]

Excellent explanation...and all done in one take!

[@randydalmas]

I need more of these videos with Simon. Great explanations on how changes affect not only the bike but how it handles and feels for a rider.

[@Gambo916]

Brilliant........can't get enough of these types of TechTalk vids.

[@waynereilly9750]

Excellent. I remember many many years ago doing a riding course at Baypark in Tauranga with Simon. Excellent at explaining things all those years ago too.

[@alexugljesic]

I knew that racing bike has a lot of adjustable elements, but not this much. Well done, thank you Simon!

[@rebatov]

These are such fascinating insights. Keep this coming guys, I wouldn't miss the TechTalk ever.

[@quandocevocevo5531]

It's clear: the gift of synthesis live other place...Simon I let hear your episodes to my son's when they get to sleep...omg

[@trentbrisket1159]

Yo! The Gift Of Synthesis would be such a great name for a metal band. Thanks, non native English speaker!

[@jaycee5101]

Brilliant video, well explained Simon, I'll still have to watch it more than once to get it all!😅 Great insight into just how much setup work can be done as well as helping us to understand possible effects of these changes. Love it!

[@mymotorbikeobsessions]

Wow! Just wow. So much awesome info in such a compact video. Thank you! Simon rocks!

[@12volttavern]

Love this series of videos!!!!! Thanks for putting them up!!! Simon kills it!!!!

[@saltyprocrastinator]

This was absolutely brilliant, please keep it up! Those machined parts are absolutely gorgeous!

[@4K_Design]

Simon, I enjoy a lot your tech videos! I know that you have to make short videos, but as chassis and its geometries are so complex, all of us would enjoy an explanation of how all these variables affect each other with grapichs or 2D images, where we could see all this parameters and also an example of a rider with a particular tech problem and how his mechanics and technicians solves it.

[@biohayzer]

So well explained and you can totally understand when even the best teams and mechanics don’t find the right set up come race day😳👍🏻🔧

[@StreetBikeTakeoverYT]

Very good information, did not know how the linkage worked until now. Thanks

[@johnstahl4210]

Awesome Simon, keep them coming!

[@thedakon]

Thank you Simon, keep 'em coming!

[@manojthapa9456]

Love Simon and love the content.

[@newnum2]

Long time ago on the RGV 500 Suzuki tried a rear suspension where the spring and damping were separate and operated on by different linkages.

[@Grazzo77]

Awesome! Simon is the man.

[@bagussantos826]

Terimakasih Simon dan Motogp atas ilmunya......keren brooo....

[@joebullwinkle5099]

I guess after a while you work out what combinations of what helps with whatever the rider is asking for. Suspension & Chassis setup sure look like a black art to me!

[@jamesstewart7224]

Nice one Simon more micro ajustments of the super specials 👍

Love to know about bikes more and more thank you for your efforts and i would like to know about gears in motogp can be mounted on street bikes so if some one comes to track they would have a better feel of gears and how we could possibly do that on our bikes

I love the series and I’m glad y’all are still doing them even though we have this virus, but the mask really does steal the show.

[@georganatoly6646]

With so many dependent variables it seems you'd want software making the recommendations for the adjustments by calculating the results of multiple change paths based on automated data accumulated from the bike/rider while out on the track.

[@giodc8599]

Not quite. The reason is that there is no perfect setup. If there were, they would all run that specific setup. Thing is, different manufacturers have a different philosophy when it comes to the machines they put on track. If your model says that setup A is the fastest but the rider is always on the edge and risking, why not use setup B, slightly slower but safer? Obviously, my considerations are only very generic. As with everything, setup is a compromise. The human factor can't be taken out of the equation.

[@georganatoly6646]

@@giodc8599 Yeah, you quickly run into trying to engineer into the bike constraints on the human. For example, a seat designed so that the human isn't allowed to move around but the bike moves the seat/human as a whole based on lean angle, brake position, and other steering geometries. It would quickly become apparent that it would be easier to remove the human altogether and design an AI to pilot the bike and then let the modeling software optimize the geometries of the bike in that context.

[@giodc8599]

@@georganatoly6646 Correct. You won't find 2 riders riding exactly in the same way even on the same bike. Don't forget a bike is developed in a specific way by a test rider. This can be a make or break. KTM seems to have done a step in the right direction, for instance. Also, weight of the rider is also very important. A heavy rider will suffer on a Moto3 whilst a light rider on a MotoGP will have an easier time taking off. Again, all about balance. There is no perfect recipe.

Speaking of adjustability, you can twist the straps on your mask a couple times so it doesn't fall off your face! Great insights as always, Simon.

Why are they revving the engine? What for? Some kind of prep or checking something?

Did suzuki ever use the full floater shock on gp bikes like the motocross lineup back in the 80s .and was said it the ultimate true rising rate suspension. It did have a lot of moving parts.bell crank, push rods and lots of needle rollers .bad Brad lakey.won the world championship on that very suspension.to complex?

Saludos desde la ciudad de México 🇲🇽👋😃 ya tienes tu super like 😃👍 🏍️

[@giodc8599]

Lots to be said about the subject. Teams use rider feedback and telemetry to see what changes are needed in order to have the bike behave in a certain way. At the same time, rider needs to have confidence in the bike. There is no point in setting up someone to a "faster" setting if that rider can't use the full potential of said settings. All the mechanics have the highly important job of delivering a bike that suits the rider, stays within regulations and goes as fast as it can. Once you start doing trackdays you'll understand how tiny changes in geometry can make a bike feel very different.
