Malossi MHR Polyamide Cage Racing Crank Bearings for Piaggio 50cc 2T

The best crank bearings available! What sets these bearings apart are the polyamide inner bearing cages, oversize inner balls and carbonitrided inner rings. These features together allow these bearings to handle a huge amount of punishment, while dissipating heat and not prematurely wearing out. Rated to C3M clearance, for ultra high revving engines. Highly recommended for scooters with full circle crankshafts.
