GPR V4s Stabilizer Kits

GPR V4s Steering Damper

The GPR V4s, the fourth generation of the GPR sport bike application. This is specifically designed for sport and street bike applications and uses our patented pin-less mounting system. Slim design and large visible adjustment dial allows you to adjust the damping settings while you ride. Vital in changing conditions and temperatures. Since is debut in 2007, this kit has become a favorite of amateur and professional road racers worldwide. The Harley Davidson applications uses the same V4s steering damper and includes a beautifully machined billet top-clamp.

Sport Bikes / Street Bikes

The GPR V4s, specifically made for sport / street / road racing motorcycles. We’ve taken our proven patented fluid control technology and squeezed, trimmed, and lightened this model up to be exactly what the racers want. Smaller, lighter, faster. A large dial with a definite “no-slip” grip that locks into place with a positive “click” at 20 settings. Approximately 30% lighter than the GPR original street bike steering stabilizer. Shorter fluid ports, new valving, quicker reacting to high speeds.

Two wheel tuners “Brappy” award for “Best Road Racing Product of 2007”. “Massive improvement over the original model” – Superbike Magazine 2007.

Since its debut in 2007 this steering damper has been on championship and race winning teams in AMA Superbike, British Superbike, Australian Superbike, the Spanish CEV championships and in the Irish Road Racing series. The list keeps growing every season for a reason…It works! It does what a steering damper is supposed to do.

The GPR V4s steering dampers available to the public is the same championship winning sport bike steering damper that our race teams use. Bolt on applications only too. No holes to drill into your top clamp and no holes to drill into your frame. Light-weight mounting brackets and all in house prototyping insure a proper fit to your bike. This is the steering damper you want on your sport bike.

Harley Davidsons

The Harley Davidson applications are developed using the same race proven street V4s street damper combined with a beautifully machined billet aluminum top-clamp. This eliminates the use of a “base-plate” mount, standard for our sport bike applications to secure the damper to. Results are a much cleaner look for the Harley models stock or custom.

And like all of GPR Stabilizer products, these are all bolt-on. No drilling, welding, or cutting to your original equipment.

Frame mounts are machined aluminum and steel hardware all anodized black. The damper colors available are black, red, blue, and gold. You can also get these kits with a chrome damper available through a special order from Sport Chrome.
