The GPRV4, specifically made for sport / road racing bikes. We've taken our proven fluid control technology and squeezed, trimmed, and lightened this model up to be exactly what the racers want. Smaller, lighter, faster.  Motostrano sells GPR Steering Dampers for Ducati, Honda Kawasaki, Suzuki and Yamaha.  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 Version 1. Available now in Black / Red and multiple color combinations in the fall of 2007. Developed extensively in the World Superbike paddock and the AMA Roadracing paddock during the 2007 with incredible results. 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.
