GPR V4 Steering Stabilizer Yamaha R1

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!

do these come with the mounting brackets or are they just the stabilizer?
A shopper on Mar 18, 2017
BEST ANSWER: It came with a mounting bracket and hardware. I definitely recommend using loc-tite thread sealant when installing it.
I have a Yamaha YZF-R1. Your site says I will be required to drill/tap to install this. GPR says nothing about having to do that. Is this an error on your site or will I need to drill?
daniel k on Mar 12, 2017
BEST ANSWER: I purchased this for my 2001 R1. I did not have to drill/tap.
