K-Tech Yamaha YZF-R1 15-24 20DDS Fork Cartridge Kit w/Springs

Fitment Note: Not for R1M models.

K-Tech DDS (Direct Damping System) front fork cartridges are a complete replacement damping system designed and manufactured in the UK for high end racing applications. The DDS cartridge is a pressurized damping system using 20mm displacing pistons to create a high flow of oil through the 31mm control valves to give precise damping control. The patent design eliminates 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 pressurized by a spring force keeping it stable under all working temperatures.
