Abstract: A motorcycle drive pulley is diametrically split to eliminate the necessity for removing the motorcycle rear wheel in order to change drive pulleys. The split drive pulley bolts to the rear wheel of a belt driven motorcycle. The pulley has a first surface which faces away from the wheel and is generally convexly dished with respect to the wheel, while a second pulley surface faces and is adjacent to the wheel and is generally concavely dished with respect to the wheel. The pulley halves are diametrically symmetric, however the first and second surfaces are nonsymmetric. The pulley is constructed from a suitable self lubricating nylon or plastic which results in increased drive belt longevity. A method for installing the pulley without the need to remove the rear motorcycle wheel is also disclosed.
