      I ride, and I am a motorcycle enthusiast. And I clearly have no fucking idea what he's talking about. It's that much difficult...

    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!

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

    @graemesydney38 4 ปีที่แล้ว +8

    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.

    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.

    @rendel5024 3 ปีที่แล้ว

    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.

    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 😊

    @DeathsStalkerRVT 4 ปีที่แล้ว +1

    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.

  • @carlsbadcad7073
    @carlsbadcad7073 4 ปีที่แล้ว

    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
      @anthonyefarr 4 ปีที่แล้ว

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