DescriptionThe whole story▼

A race-proven shock absorber that slots straight into your Street Triple 765 without demanding a full race budget or factory support — the K-Tech TRDS-R delivers Championship-grade suspension control for riders who need reliable, consistent performance on every outing, from trackday Tuesdays to full race weekends.

Key Features

  • Through-Rod technology eliminates the need for an external reservoir, keeping the package compact and making fitment straightforward on the Street Triple 765 platform.
  • The 'R' stands for Regulation — engineered specifically to meet championship price restrictions while still offering the precision adjustment used in British Superbike and Isle of Man TT competition.
  • Improved heat dissipation maintains consistent damping characteristics across long race distances, so the shock performs the same on lap one as it does on lap twenty.
  • 18-click compression and 18-click rebound adjustment (suggested baseline) give riders and technicians a clear, methodical route to dialling in handling without specialist equipment.
  • 9 mm preload (suggested baseline) and 4.00 mm RCU adjustment range allow fine-tuning to suit rider weight, riding style and circuit conditions.
  • Suits all three Street Triple 765 variants — S, R and RS — covering model years 2017 through to 2026.

Everyday Usability and Real-World Value

Not every rider has a dedicated suspension technician on speed dial, and the TRDS-R is built with that reality in mind. The suggested baseline settings — 18 compression clicks, 18 rebound clicks and 9 mm preload — give any competent home mechanic a sensible starting point, while the clearly defined adjustment ranges make it straightforward to work toward a personal setup. Because the Through-Rod design requires no external reservoir, routing and installation are cleaner than many comparable units, and the reduced component count means fewer potential leak points over the life of the shock.

Race Heritage, Road and Track Credibility

The TRDS-R sits at the top of the K-Tech single-shock range and has been campaigned at the highest levels of UK and international motorcycle racing, including the British Superbike Championship and the Isle of Man TT. That lineage translates directly into a unit that handles the punishment of repeated hard braking zones, high-speed compressions and sustained corner loads without fade. For the Street Triple 765 rider who uses the road as well as the circuit, this level of damping consistency turns every ride into a more controlled, more readable experience.

Fitment and Compatibility

This shock absorber is a direct fitment for the following models:

  • Triumph Street Triple 765 S (2017–2026)
  • Triumph Street Triple 765 R (2017–2026)
  • Triumph Street Triple 765 RS (2017–2026)
