This HRF dirt bike whip mount is designed specifically for the 2019 - 2023 Kawasaki KX450 dirt bike. It mounts up under the rear fender next to the muffler.
Installation:
You just need to remove the side number plate to get to the muffler mounting bolt and the lower fender bolt. Remove the exhaust mounting bolt and loosen the lower fender mounting bolt, then you can slide the HRF whip mount in-between the muffler and sub-frame and into the lower fender mounting bolt. Now reinstall all the mounting bolts and the side number plate.
