GPR V4 Steering Damper Buell XB 12 R Firebolt

The GPR V4 Stabilizer was specifically made for sport and road race bikes. GPR has taken their proven fluid control technology and squeezed, trimmed, and lightened this model up to be exactly what the racers want. A large dial with a "no-slip" grip that locks into place with a positive "click" with 20 settings. Approximately 30% lighter than the GPR V1.

Developed extensively in the World Superbike and the AMA Roadracing during the 2007 season with incredible results.  The GPR V4 Steering Dampers that are available to the public are the same championship winning steering dampers that GPR’s race teams use. Racers and teams such as; multi- time "Isle of man TT" winner John McGuinness, Ireland's Ryan Farquhar, BSB Team Padgetts Honda, and BSB Team Hawk Kawasaki, Joe Rocket Honda with Adam Ferguson and Josh Brooks. In the AMA paddock you'll find the new GPRV 4 on the Corona Honda, Hooters Suzuki, Grant Matsushima's MPT Suzuki, and dozens of privateers. The list keeps growing every season for a reason. It just works!

Marten M asked: Does this come with all the necessary brackets for the Buell XB12r Firebolt, or is this just the stabilizer with no brackets? Jul 28, 2014

Jonathan G: I don't know about the Buell, but I bought this for my R6 2012 and it came with all the necessary parts to install. If the stabilizer is said to fit on your Buell, I wouldn't see why it would not include the brackets.

Marten M: Well, the Stabilizer that is required on my bike is completely different from your setup.
As much as I would like to hope for the best. I never assume anything when it comes to parts. I want to be 100% sure that everything I need, comes with the Stab.

Thank you for your reply. It has def. helped point me in the right direction. Jul 28, 2014
Nii-Kwao K: Don't know much about Buell but all the parts necessary for mounting was included for my 98 Yamaha R1. I would assume yes. You can also call GPR to verify. Jul 30, 2014
