K-Tech TRDS-R Closed Cartridge Kit – Triumph Street Triple 765 RS (2017–2026)

Built from the same components trusted at British Superbike and the Isle of Man TT, the K-Tech TRDS-R Closed Cartridge Kit brings race-grade suspension engineering to the Triumph Street Triple 765 RS. Every element of this kit reflects K-Tech's obsession with material quality and precision manufacturing, delivering a level of damping consistency that stock internals simply cannot match.

Key Features

• Through-Rod Damping System (TRDS-R) provides exceptionally precise, repeatable damping adjustability — the 'R' stands for Regulation, enabling fine tuning of suspension behaviour within controlled racing environments.
• Lightweight, compact closed-cartridge construction improves thermal dissipation, maintaining consistent performance across extended race distances without fade.
• 16-click compression and 16-click rebound adjustment (recommended baseline settings) allow riders and technicians to dial in the chassis with confidence at every circuit.
• 18 mm preload adjustment range gives further flexibility to accommodate different rider weights and track conditions.
• Supplied with a matched spring set, so the kit is ready to install as a complete, balanced suspension solution.
• Proven at the highest level of British and international motorcycle competition, including BSB and the Isle of Man TT.

Engineering & Build Quality

The TRDS-R represents K-Tech's closed-cartridge technology at its most refined. The through-rod architecture ensures that damping forces remain linear and predictable under sustained load — a critical advantage when consistency between laps is the difference between a podium and a points finish. The compact internals reduce unsprung mass while the engineering-grade materials used throughout the cartridge body and rod assembly resist wear and heat build-up in a way that OEM units are not designed to.

This kit is particularly well suited to riders and teams operating within class regulations or with limited sponsorship budgets who need a genuine performance upgrade without compromising on engineering integrity. The TRDS-R delivers the adjustability and durability of a full race unit in a package that remains regulation-compliant and cost-effective to maintain.

Fitment & Compatibility

This kit is designed and manufactured specifically for the Triumph Street Triple 765 RS across the full production run from 2017 to 2026. No modification is required for correct fitment. Installation by an authorised K-Tech Service Centre is recommended to ensure correct setup and to preserve warranty validity.
