For Sale - Classic BMW boxer engine motorcycle, 750 The bike runs great. I just had it completely serviced at a motorcycle shop that works on classic motorcycles - $2000.00 repair fee to bring it back from the dead. I'm the second owner. Issues: front wheel is not original, engine emblems are missing, battery covers missing, small tear on seat, bad tachometer. Good: engine runs great, paint in very good condition, motor and frame match, brakes, transmission, lights, signals, horn, electrical are all good.
