RS 125 NX4 wire harness cut down specially for micro sprint application. We build the harness from the ground up. We get rid of all the useless plugs from the bike application and make it super simper for the micro sprint racer. We cut every wire down to a exact length so you wont have any extra wires to tie up and make a mess under the hood. Our harness also features a plug for the kill switch this makes taking the engine off just that much eaiser. No more looking for tiny screws off the switch after you drop them. With the factory harness no longer availble we wanted to build something with the micro sprint teams in mind.
