Description

Crafted from CNC machined billet T-6 aircraft-quality aluminum, this kit is built to aerospace-grade tolerances. Its components are Akadized for superior wear resistance compared to stock parts. The design focuses on reducing heat buildup and allowing the clutch assembly to spin more true, which results in less heat generation when the clutch is disengaged. This leads to smoother and more precise engagement. The kit includes a Clutch Basket, Inner Hubs, Pressure Plate, Steel Plates, Fiber Plates, Clutch Spring, and Clutch Cover. This clutch kit has been tested and proven in competitive racing environments, used by all major factory teams and riders. It is specifically designed for the 2021-2023 Kawasaki KX450, KX450X, and KX450XC models.
