If you want a tougher clutch setup, the XRAY 359051 oversized clutch bell ball-bearings are a practical choice. These 5x12 bearings replace standard 5x10 units and use 2.0mm balls plus beefed up bearing walls to better cope with heavy loads and long race conditions.
The larger ball diameter and thicker walls increase endurance under stress, reducing the chance of bearing collapse during extended high-performance use. These are especially useful where the clutch sees sustained high RPMs.
The kit includes a specialised high-temperature grease that keeps lubrication consistent under heat. That stabilises clutch feel and helps cut down on frequent maintenance stops.
