The PMR Killswitch was designed to stop the engine if the rider loses control of their bike.Our switch is a normally closed type switch and replaces the stock bar clamp on most 7/8 handle bars. Always pull out the plug by the plug itself and not the cord. This will prevent damage to the wire and plug. FITS Suzuki Hayabusa (all) GSXR1000/750/600 Kawasaki ZX-10R (04-05) Kawasaki ZX-14 (06-07)
