Beta RR 390 4 T Enduro Racing [2019] - Pro Race steel and friction disc clutch kit

NEWFREN Pro Race steel and friction disc clutch kit for Beta RR 390 4T Enduro Racing

The Pro Race clutch kit from NEWFREN combines friction plates and steel discs for the clutch of the Beta RR 390 4 T Enduro Racing from 2019. The Pro Race Line was developed in collaboration with successful teams from the Superbike, Moto 3 and MXGP world championships and is designed as a high-quality racing product.

Friction material and disc design

The friction material mainly consists of cellulose, resins, carbon and other components. This means it has a high coefficient of friction and is less compressible. The special design supports improved oil flow, allowing the discs to work more efficiently. The combination of material and construction promotes stable function of the pads even under demanding operating conditions.
