BETA CYLINDER D.39,5 TRIAL-50/97

Fitted from the factory, the BETA CYLINDER D.39,5 TRIAL-50/97 (OEM 12.52471.057) is Beta’s original cylinder. It houses the piston and sets bore condition and compression.

Re-bore or replace once the bore is scored or out of tolerance. Genuine OEM means exact fit, correct materials and no guesswork — and it protects your warranty.
