The K-tech Off Road Valve System is a replacement valve system for the WP 48mm Open Cartridge XPLOR forks. The ORVS replaces the original compression and rebound damping assemblies along with the adjustment needles giving improved damping characteristics and wider adjustment range, enhancing overall ride quality and stability to the motorcycle for all terrains. Like all K-tech high performance products we recommend that this product is fitted by a qualified suspension technician using all the K-tech recommended tools for the procedure.
