Can you elaborate? MX guys use brakes and throttle to control pitch while in the air. I think it's called angular momentum, or something like that. Only difference is that the pivot point in this case would be the front wheel and not the center of mass.

Actually prodigy you seem to be really good at stoppies, can you do a stoppy while keeping the rear tire spinning as fast as you can. Now while at the brink of falling over the front, then slam on the rear brake. Please film as I want to see what happens.

Please give them a try at 120 as well!

Yeah...speed might be a small factor in stoppie physics.

This is true. However, they don't actually brake with the tire in the air.

Most of my long stoppie I pick the rear tire up around 100mph. Jesse Toler who I compete against is a world record holder for not only the fastest but the longest. The weight and momentum of a sport bike is far greater than that of a dirt bike. So the input from a a spinning rear tire has little to no effect.

Just did. It adds near nothing except a possibly wagging end. Take your scooterlogic elsewhere.

I'm legitimately curious about this not just stirring a pot or anything. Have you locked up the rear after it's been spinning fast while in a stoppy? I'm curious to know if it would transfer enough momentum to the bike to make a difference.

I guess I should have clarified. First time I'd heard it described was in a step up competition, not during a race when they're trying to scrub height. They'd lock the rear as they cleared the bar and the front would just dive. This is sorta what I was talking about.

Quote:
THREE: Up ramps on step ups are generally steeper than most jumps so it's important to let the bike change angle underneath you and not let your weight go too far back as you take off. It the front wheel comes up too high then pull the clutch in and stab the rear brake mid air to help bring the front wheel back down.

Nope, it still sounds like you don't know what you're talking about.
