Re: STOPPiE PRACTICE
The force exerted on the wheel to make it stop is the friction force exerted by the brake pad on the rotor. The equal and opposite force to that is the friction force the rotor exerts on the brake pad. NEWTONS 3rd law

Re: STOPPiE PRACTICE
Your right about the action-reaction pairs. That is Newtons 3rd law. But thats not the correct reason in this case. Whats going on is simply this.... Anything spinning has angular momentum. So when the rear wheel goes from a state of spinning to not spinning the angular momentum changes. Anytime the angular momentum of an object changes a net torque results. Its this torque that provides that extra bit of lift. Its easier to describe on paper but thats the best I could do in words.

whats the verdict? keep it spinning or stop it?

Re: STOPPiE PRACTICE
i did notice that when you stoppie you body posision is way off. you fight the bike to much. try and let the bike guide you at the same time.

Re: STOPPiE PRACTICE
Let the wheel spin until u come to a stop. Right b4 u touch down, step on the rear brake. The gyroscopic energy will help keep the bike up. If u get ballsy, slip the clutch and use some gas while ur up. But I'm guessing ur new to the stoppie game so u might wanna save that for next year bro...GOOD LUCK
