Technical description

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. For the 2017 PDS models of KTM the size and weight of the TRAX System was reduced, while friction-.optimized parts and lower production tolerances ensure an even higher performance level.

Installation Guide

WP TRAX Shock Absorbers replace the original shock absorber. They are designed to fit in the original frame. The shock absorber can also be reused for other motorbikes of the same type. The shock absorbers can be fine-tuned by any WP Distributor to match the requirements individual tracks or usage (e.g. Rally). Additionally a wide range of simple adjustments allow the rider to fully adjust the shock. WP TRAX Shocks are tested and designed to offer the highest performance in combination with the WP Cone Valve Forks.
