The GPRV1, the original design.  Well close to it. It still retains approximately the same shape as the original, but the internals and adjustments, sensitivity, sweep breaks were all fine tuned over the years.The end result is a steering damper that is very reliable durable, re-build-able and best of all...affordable. The steering damper that has won hundreds of off-road championships and road racing championships around the world is the same "budget" steering damper you can get at your local dealer.
