Made specifically for sport/road racing bikes. Designed to help reduce rider fatigue and eliminate headshake, improving lap times. Proven fluid control technology that's been squeezed, trimmed, and lightened to be smaller, faster and lighter. Shorter fluid ports, new valving, quicker reaction to high speeds. 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. Developed extensively in the World Superbike paddock and the AMA Roadracing paddock .
