YAMAHA RC50 Recalls

The Yamaha RC50 has 1 recall affecting the 1975 model year, where an oil delivery pipe that is slightly too long can kink during setup, cutting off oil flow to the engine, seizing the piston, and causing the rear wheel to lock suddenly until the rider disengages the clutch. A locked rear wheel at speed can cause the bike to skid or go down before the rider has time to react. The root issue is that the pipe routes oil from the tank to the injection pump, and once kinked, the engine runs without adequate lubrication until internal damage occurs.
