lemming:Sectorsteves motorcycle is the only one I've ever heard of bending the swing arm. I'm still trying to figure out how that could possibly happen by just using the rear brake. There isn't that much torque on the rear brake even if the rear wheel is locked up.If the rear brake shoes are adjusted correctly, the coil spring on the rear brake lever will automatically disengage the rear brake as soon as the riders foot releases the pressure on the brake pedal. Don't worry about it but remember, the front brake on your motorcycle does over 80 percent of the braking.Several racers I know only use the rear brake to keep the rear of the bike from coming around under heavy braking. (I'm talking about 120 mph down to 20 mph for a sharp turn).
