Replaces the stock kill switch or starter switch on all motorcycles, atvs and minis that have a 30-32mm span between the clutch or front brake mounting bolts. The switch replaces the clamp that holds the clutch lever or front brake master-cylinder onto the handlebars. It eliminates one or two strap mounted switches completely from the motorcycle to make handlebar changes faster and easier. It also creates more space for handguards, lap timers and other handlebar mounted accessories. For those that ride electric start motorcycles, a second switch can be added to eliminate the stock start button. Installation is simple and explained in the enclosed instructions by splicing in two wires. NOTE: CRF450R ’09-16 & CRF250R ’10-16 kill button requires LED light M05-750031. KX450F ’12-21, KX250F ‘14-21, RMZ450 ‘15-21 & RMZ250 ‘16-21 launch control requires LED light M05-750031.
