  • '16-'20 RSV4-RR

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 pressurised damping system using 20mm displacing pistons to create a high flow of oil through the 31mm control valves to give precise damping control.

The patented 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 pressurised by a spring force keeping it stable under all working temperatures.

  • 30 clicks rebound
  • 18mm spring preload
  • 8mm piston rod
  • 20mm displacing piston
