This genuine OEM Hitachi 12V ignition coil, casting number CM11-50, is designed for vintage Yamaha motorcycles using contact breaker points ignition. This single-output coil converts low-voltage battery power into the high-voltage spark needed for proper engine combustion. It includes the integrated high-tension spark plug lead boot, low-voltage bullet terminal leads, and dual chassis mounting studs for factory-style installation beneath the fuel tank.
