Beta RR 390 4 T [2020-2021] - Pro Race steel and friction disc clutch kit

NEWFREN Pro Race clutch kit for Beta RR 390 4 T

The Pro Race steel and friction disc clutch kit from NEWFREN is intended for the 2020-2021 Beta RR 390 4 T. It combines friction plates and steel discs with a specially designed disc design that supports oil flow, allowing the clutch to operate more efficiently.

Friction material and construction

The friction material mainly consists of cellulose, resins, carbon and other components. Its properties are designed for a high coefficient of friction and lower compressibility. In conjunction with the design of the discs, this supports the stability of the pads even under demanding operating conditions. The Pro Race clutches were developed in collaboration with teams from the World Superbike, Moto 3 and MXGP championships.
