Naraku Rollers 18 x 14


Here you go, it’s time to get those old rollers replaced, or you’ve done some modifications and want to get your scoot in tune. Rollers are the way you set the engine speed. Lighter weight raise engine speed, heavier weights lower engine speed. Be careful, higher is not always better as you can rev right past your torque curve and just spin out without any thrust. Too heavy a weight and you will be below your torque curve.
