TrueFan: Given that Marc usually has the rear wheel airborne under brakes, he probably finds the foot operated brake applies too much force.


Given it some thought, if his foot is free to do what ever it wants he can use it to balance the bike out and also push the back down while braking.

Could be a very good thing for him.

Whats the saying it's hard to teach old dogs new trick, but he's still young.

Or mind games for the Yamaha boys ?

Well applying rear brake doesn't get your rear in the air. Thumb brakes are usually used because in right turns you stand on your toes on the rear set and can't use the rear brake. Rear brake usage actually makes the whole bike squat when used with the front, so less rear wheel air time.

Given your user name, I'm sure you're aware that most of the braking is done with the front brake, and when applied hard enough, the weight transfers almost entirely onto the front wheel. If you watch Marquez, his rear wheel is often either skipping in the air, or completely unloaded until he tips it in. He initiates most corners over the front wheel. It is quite brilliant, and his corner entry in particular is poetry in motion. It looks loose, but he does it at will. The rear brake will bring a wheelie under control, or stabilise the bike in some cases. Maybe they have a better feel using a thumb control. They don't need much force for it to be useful.

RaceRoad:
VonS: He will be better than Doohan.


only doohan didnt have the "i save you whatever mistake you make ecu" for me thats a way bigger achievement!


Yes but the NSR was only about 160 BHP about a 100 BHP down on todays bikes. I'm a a Doohan fan and always will be.
