This complete assembly smoothes the power delivery by adding 4.4oz to flywheel weight, in effect increasing inertia mass over stock by 3.2kg/cm2 (total of 9.5kg/cm2). Helps get power to the ground and keep your momentum up through corners and tricky sections, resulting in faster lap times and more race wins.
Easy to install, allowing you the opportunity to change flywheels for different types of riding.
This accessory is restricted to closed-course use.
