GPR stabilizers have been in the motorcycle industry for years. Anyone with a dirt bike, quad, ATV, or sportbike knows the GPR stabilization components are second to none. A few years back, GPR decided to see if it could appeal to the H-D market by trying to help relieve the frustrations of high-speed wobbles on XL and Dyna models. The crew at GPR had to make a kit that could allow the GPRV4 to mount easily yet remain as close to OEM specs as possible. The end result was a kit that consists of a triple tree, damper, and frame clamp that is easy to install, made of top-quality materials, and works like no other steering stabilizer system.

We begin the install by securing the bike on the lift. Doing this installation without a jack is a bad idea.

Once removed, you can lay the bars on the tank. This will provide you ample room to change the top tree without disconnecting the bars from the bike.
