Beta RR 390 4 T X-PRO [2025-2026] - Pro Race steel and friction disc clutch kit

NEWFREN Pro Race clutch kit for Beta RR 390 4 T X-PRO

The Pro Race steel and friction disc kit from NEWFREN is intended for the Beta RR 390 4 T X-PRO from 2025-2026. The combination of friction disks and steel disks forms a coordinated solution for the clutch and is aimed at use in racing.

Friction discs with coordinated design

The friction material used mainly consists of cellulose, resins, carbon and other components. It offers a high coefficient of friction and is less compressible. The special disc design improves oil flow, supports more efficient operation and increases the stability of the pads even under demanding operating conditions.

The Pro Race line was developed in collaboration with successful teams from the Superbike, Moto 3 and MXGP world championships. The clutch kit thus combines technical design with a clear focus on racing use.
