Cush Drive Rubbers (5 pcs)

Rotobox wheels use Polyurethane Cush drive rubbers to improve rider comfort by reducing shock and vibration transmitted from the motorcycle's engine and transmission to the rear wheel. These Cush drive rubbers act as a buffer or dampener between the wheel hub and the sprocket carrier, absorbing and dissipating the impact forces that occur during acceleration and deceleration. We recommend replacing cush drive rubbers after about every 3000 km of riding. Fit Boost, Bullet, and Bullet Pro models.
