You can literally see the passion on Simon's face :)

This guy is outstanding! Bravo!! I'm gonna mount a 44 sprocket, adjust my swing arm pivot height and make a beer run. Be right back!

@drew657 4 года назад

Better make that beer run first. Gotta have proper shop equipment on hand before starting a job!

@stevemackelprang8472 4 года назад

Simon Crafar is the hot tune for motogp, I really enjoy his knowledge of the workings of the paddock. ... real insight beats chatter any time.

@salsyou 4 года назад

Agreed 100% He is the best.

@graemesydney38 4 года назад

At the MotoGP level, I'll bet there are some awesome spreadsheets/algorithms used by the mechanics to work out the gear ratios - calculating, primary, secondary, internal ratios, and projected speeds for each corner, uphill, downhill and straight.

@GR-yf1cm 4 года назад

Awesome .. love your tech talks Simon adds that little bit of extra information and enables us to be a little more than just a spectator

@ridhojms227 4 года назад

I know a lot about gear ratio setting, primary and final gear from playing sim racing game many times 😁 and having many options in ratio setup like Motogp is better than limited options like Moto3, so you can set the ratio freely. you explained very well simon 👍 your background makes you know every detail of bike setup.

@pete5534 4 года назад

Maybe riders and their mechanics would make great world leaders. Imagine the level of communication involved to pull off this magic. Thank you Simon.

@robertreynolds9228 4 года назад

Thanks for the info mate.

@DeathsStalkerRVT 4 года назад

Back in my 250GP days my Honda had a cassette gear box with multiple options for each gear. It only took a few minutes to switch them out and Honda provided a spread sheet to show you what the ratios would be when you mixed them up. It was so confusing with small print I had it copied to 11x17 paper just so we could read it. Luckily once we figured out how to use it we found we would change only 2nd to 4th gears along with the sprockets most of the time. Oh and when of those internal gears broke they made horrible noise so you knew right away you race was over.

@rendel5024 4 года назад

MotoGP is on free to air TV in Australia, but the lower classes aren't. They're so much technology that's in all three classes, that I'd love to see all of the races and more of this type of behind the scenes videos.

@oklahomahank2378 2 года назад

Hi Simon, Thank you for the wonderful explanation. I have a small and basic question, what is the different between engine braking and rear brake braking? Please forgive me if it sound stupid 😊

@VBshredder 3 года назад

Just came across these tech talks tonight, not sure why I haven't seen them, but looks like i'll be up late.

@carlsbadcad7073 4 года назад

So when I raced and wanted to keep the swing arm length, we would use 2 master links; in between the 2 master links we had different small lengths of chain, one link or one link and a half up from 1 link(link and a half) up to 15 links, etc. Worked great, in 13 years never had a problem doing this.

@anthonyefarr 4 года назад

I thought that was the normal arrangement. Simon seems to imply that you cannot change the chain length on a Moto2. I'm surprised...

@BangAverageRider 4 года назад

Loving this series, so much information. I'm in shock that a Moto 2 bike can be geared to 315KPH!!

@raynic1173 4 года назад

That might be a 'theoretical' calculation. As far as I know there are only a few tracks where even the MotoGP bikes reach that speed. It takes a lot of horse power to reach the 300+ area, even if you have the room in front of you, just look at the street versions of liter bikes. Most liter bikes will top out around 320-335 and they have way more hp than a stock 600 cc Moto2 bike.

@tazthedevil22 4 года назад

@@raynic1173 at Qatar the Ducati world superbike bikes could hit 324kph. I dont know what the gp bikes do at that track? But hitting 315 on a 765cc engine is a lot, but I guess it is possible.

@BangAverageRider 4 года назад

@@raynic1173 the Japanese manufacturers have restrictions to limit modern 1000cc to 300kph.. The moto 2 bikes are capable of that but like you said maybe not much more due to horsepower but it would be great to see one on a run way attempting a top speed test
