GPR Stabilizer is a family owned and operated business with a pure passion for every discipline of motorcycle racing.
The GPR Stabilizer was born of frustration. Fed up with the lack of quality and selection at the time, Ralph and Randy Norman set out to make the best steering damper available for off-road racers. They started with an original design created from previous testing and prototyping. Helped by their background in aerospace manufacturing and design, it evolved into the dominant steering damper at any off road venue today. Now, with patents held in the USA and abroad, GPR has set its sights on the world racing market.
The success from GPR's professional road-, off-road-, and ATV-racers around the world has allowed them to develop what racers are asking for: a motorcycle steering damper that is lightweight, small, adjustable on the fly, and easy to service. With applications for just about every popular make and model of performance motorcycle, GPR steering dampers are top-of-the-line. The GPRV4 was designed and developed specifically for sport bikes and road racing bikes and is now used by some of the biggest names in racing.
On any given weekend, one GPR rig will be at an AMA Road Race, another at a WORCS off-road championship, and another in the World Superbike paddock. GPR Stabilizer is currently the only American sponsor of the World Superbike Championship and the only rotary steering damper on the World Supersport grid. Thanks to successful partnerships with their distributors, racers, and teams, GPR Stabilizer has racked up championships across the globe and is represented and distributed in over 24 countries.
Every part of GPR Stabilizer is produced under one roof in the USA. Design, manufacturing, assembly, testing, and distribution are all done at their San Diego, CA facility. GPR is the only steering damper company to provide it all for you: lifetime service warranties, color selections, range of applications, service in the paddocks, and most importantly, constant improvement.
How many different dampening settings does the GPR have?
The numbers are strictly for reference, so you can visually/physically know what adjustment you are at. No guessing or fumbling required. Every degree you turn the knob is a different setting, allowing you to fine tune the damper unit to your needs. The knob assembly rotates 360 degrees left or right allowing you to go straight from the softest setting to the hardest setting, if need be. It will not unload, unscrew, or pop out, disabling your damper unit. The lower the number, the softer the setting. The higher the number the harder the setting. Very simple and very effective.
Does GPR actually make the stabilizer, or just sell/distribute them?
GPR is proud to say that they manufacture, assemble, and test every GPR unit in their San Diego facility. The only thing they outsource is our seals, bolts, and oil. Every damper mount and post mount bracket is R&D'd, then manufactured in house for a true 100% fit and quality assurance. Instead of a cast mold post mount, or a one "fit all" drill and tap bracket, all mounts and brackets are CNC machined in house for top quality. GPR has the knowledge of prototyping a new bike in a relatively short turn around time, usually in just a few days. GPR doesn't like to wait for others to fabricate a mount first. That's why GPR post mounts/brackets are often imitated, but never duplicated.
