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.

The bike is now ready to undergo the process of taking off the top triple tree. Make sure you have your gas tank covered so nothing gets scratched or dented.

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.
