Technical description

The all new WP 85 TRAX Shock Absorber is equipped with the WP TRAX Shock Absorber technology and will significantly improve the rideability and handling of the bike. WP-TRAX Shock Absorbers are the most innovative shock absorbers on the market. The TRAX unit is a very compact system in the bottom mounting fork of the shock, which significantly improves the grip of the rear wheel. This system has been successfully implemented by the Factory Racing department and many World Championship titles prove how effective it is. The TRAX system has been developed in order to reduce the time frame after a bump where acceleration is not possible because of the slow rebound of the rear wheel. The TRAX system registers when the rear wheel has no ground contact and immediately opens an oil bypass so that the rebound can expand faster than is possible with a conventional system.
