PROX Crankshaft Bearing 25x55x15mm — replacement part by PROX, designed to restore smooth and jerk-free engine behavior on compatible small twin-cylinder and roadster models. This bearing in the 25x55x15 mm format matches the original specifications for a direct replacement of the worn bearing, ensuring correct crankshaft rotation.
Ideal for engine maintenance operations (bearing replacement, case refurbishment, axial play check), this bearing is aimed at riders who want to restore their engine while adhering to manufacturer specifications. A bearing in good condition minimizes play on the crankshaft and contributes to smoother rotation — however, always follow the manufacturer's recommendations and check the condition of the bearing holder and support surfaces before installation.
