DescriptionThe whole story

Unlock the full potential of your Triumph Street Triple 765 RS without sacrificing everyday comfort. The K-Tech DDS Closed Cartridge Kit replaces the factory fork internals with a Direct Damping System that delivers precise, independent control over compression and rebound — whether you're threading morning traffic or pushing hard on a weekend blast.

Key Features

  • Direct Damping System (DDS) provides genuinely independent compression and rebound adjustment, so you can fine-tune ride quality without compromise
  • 20 mm main piston paired with a 31 mm control piston for accurate, consistent damping response across a wide range of road and track conditions
  • 16-click compression and 18-click rebound settings (factory recommendation) give an accessible starting point for riders of all experience levels
  • Closed cartridge design keeps the damping circuit isolated from fork oil, maintaining performance integrity over long service intervals
  • Bolt-in fitment for the Street Triple 765 RS (2017-2026) means no machining or custom fabrication — a straightforward workshop upgrade
  • Compatible with K-Tech 36-260 series springs for a complete, matched front suspension package

Everyday Usability and Real-World Performance

Where many aftermarket cartridge kits demand a trade-off between track sharpness and road comfort, the DDS architecture avoids that compromise. Because compression and rebound circuits operate independently, you can run a compliant, forgiving setup for daily riding and wind in more compression support for spirited weekend use — all without removing the forks. The 20 mm piston diameter keeps damping forces precise at low shaft speeds, smoothing out urban imperfections that a stiffer, track-biased kit would transmit directly to your hands.

Construction and Engineering

K-Tech manufactures the DDS Closed Cartridge Kit to competition standards, using the same closed cartridge architecture found in their dedicated race products. The 32 mm outer diameter and 688 mm overall length are engineered specifically for the Street Triple 765 RS fork legs, ensuring correct oil volume and spring preload geometry. Pairing the cartridge with the recommended 36-260 series spring completes the front-end rebuild and ensures the damping tune works within its designed operating range.

Fitment and Compatibility

This kit is designed specifically for the following motorcycle:
