Genuine Yamaha Crankshaft Bearing Warrior 350 XT350 SR400 OEM NEW
Brand New, Genuine Yamaha OEM Crankshaft Main Bearing (Part Number: 93306-30630-00). This is a high-precision, Japanese-made engine bearing designed specifically for the heavy loads and high RPMs of Yamaha’s 350cc and 400cc engine platforms.
