GPR V1/V2 Stabilizer Kits

GPR V1 Damper

This is GPR’s first generation design of a rotary steering damper, well close to it at least. It still retains the original footprint but internal valving and fluid controls have evolved over the years. One center dial, adjustable as you ride and completely rebuildable. Take the V1 damper and mount it under the bars for the V2 version. Mounting the damper under the bars give the taller riders the bar height they are looking for and keeps the shorter post mount flex to a minimum.

GPR V1 / V2 Dirt Bike Application

The V1-V2 designation is V1- standard top-mount dirt bike application. Damper mounts to the specially machined GPR top bar mount. The customer will use their stock bottom bar mount and hardware or with the cast clamps, the bottom mount is cast into the top-clamp. V2 designation is the V1 damper is mounted underneath, below the handlebars. The machined GPR bar mount will raise the bar height approximately 1.5-1.75 inches. Since the damper in now below the handlebars the frame mount height is quite shorter than on the V1 application. Frame mounts for the dirt bike applications are all machined and welded steel. Stainless steel pin with aluminum collar tops it off with the connection to the damper.

GPR V1 ATV Application

The GPR V1 is used for the ATV applications with a few modifications to better suit the condition and forces produced from the much heavier quads. Modifications for the V1 ATV damper is a high strength stainless steel empeller vane and the elimination of sweep-breaks. Billet machined heavy-duty mounting plates ensure a stable and secure mounting point for the damper.
