The K-tech Off Road Valve System is a replacement valve system for the WP 48mm AER forks fitted to Husqvarna and KTM 125cc and above motocross bikes from 2016 onwards. 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.
