We stock Starter Motors for all models of motorcycle, scooter and quads including Honda, Kawasaki, Suzuki, Yamaha, British & European manufacturers. The motorcycle or scooter starter motor is a powerful electric motor, with a small gear (pinion) attached to the end. When activated, the gear is meshed with a larger gear (ring), which is attached to the engine. The starter motor then spins the engine over so that the piston can draw in a fuel & air mixture, which is then ignited to start the engine.
