The KTR-4 front forks use the patent championship-winning DDS (Direct Damping System) technology, which has been designed to compete at the highest levels of motorcycle racing. The DDS pressurised damping system has 20mm displacing pistons, to create a high flow of oil through the 32mm control valves, giving precise damping control, eliminating any cavitation, making the system very stable under extreme conditions. The damping circuits are designed to work independently to improve the dynamics and response time. The system is pressurised by a spring force keeping it stable under all working temperatures.
