DescriptionThe whole story

Engineered in the K-Tech tradition of precision suspension engineering, the Road Steering Damper Kit for the Triumph Street Triple 765 RS brings a purposeful, race-derived design to daily road riding. Its clean, compact profile sits naturally on the Street Triple's chassis, while the integrated CSC (Constant Safety Control) system works continuously in the background — absorbing tank-slappers and high-speed wobbles before they reach the bars.

Key Features

  • 22-position adjustable damping — dial in exactly the response your riding demands, from relaxed touring to spirited back-road riding.
  • CSC (Constant Safety Control) system provides consistent protection against sudden, uncontrolled steering inputs without sacrificing steering feel.
  • 8 mm piston rod with specialist surface treatment delivers a low-friction, silky-smooth stroke at every damping setting.
  • Triple seal arrangement — dust wiper plus dual oil seals — keeps contaminants out and oil firmly in, maintaining long-term performance.
  • Nitrogen-pressurised reservoir eliminates fluid aeration and cavitation, guaranteeing consistent damping force on long, demanding rides.
  • Fully serviceable design with a supported spare-parts supply, so this is an investment that outlasts multiple sets of tyres.
  • Precision-matched mounting hardware included for a clean, correctly aligned installation with no fabrication required.

Design, Finish and Heritage

K-Tech Suspension has been a fixture in professional racing paddocks for decades, supplying works-level damping hardware to teams competing in British Superbikes, World Superbikes and beyond. The Road range distils that heritage into components that look and feel the part on a production machine. The Road Steering Damper carries the same considered engineering approach as K-Tech's competition units: a single, centrally guided piston rod that eliminates side-loading on the seals, high-quality bearings at both mounting eyes for smooth articulation under load, and a finish that holds up against weather, chain lube and vibration without corroding or fading.

On the Road

The Street Triple 765 RS is one of the sharpest-steering naked bikes in its class — a quality that rewards experienced riders but can unsettle confidence at motorway speeds or on rough, mid-corner surfaces. Fitting the K-Tech Road Steering Damper does not blunt that responsiveness; instead it sets a floor on instability. The 22 available click-positions let you soften damping for familiar twisty roads and firm it up for cross-country motorway runs or track days. Installation is straightforward thanks to the bike-specific bracket system, though K-Tech recommends fitting through an authorised K-Tech Service Centre to ensure correct alignment and torque settings.
