DescriptionThe whole story▼
The K-Tech TRDS-R is a race-derived rear shock absorber that brings genuine British Superbike and Isle of Man TT technology within reach of club racers and track-day riders who need measurable lap-time gains without an unlimited budget. Built around K-Tech's Through-Rod technology and engineered specifically for the Suzuki GSX-R 1000 model years 2017 to 2023, the TRDS-R delivers the kind of precise, repeatable suspension adjustment that used to be reserved for factory-backed teams.
Key Features
- Through-Rod technology provides highly accurate damping control, giving riders and technicians a reliable baseline from which to fine-tune chassis behaviour at every session.
- The 'R' in TRDS-R stands for Regulation — the unit is designed to comply with series price restrictions and relaxed racing regulations, making professional-grade suspension accessible to a far wider field of competitors.
- Reservoir-free compact design simplifies fitment and reduces unsprung weight, while the inherently efficient heat dissipation of the Through-Rod layout maintains consistent performance deep into a race or long track day.
- 18-click compression and 18-click rebound adjustment (suggested baseline settings) allow precise, tool-free tuning between sessions to suit track surface, tyre choice, and rider preference.
- Proven at the highest levels of British Superbike and the Isle of Man TT, delivering confidence in the unit's durability and outright performance under extreme conditions.
- Installation by an authorised K-Tech Service Centre is recommended, ensuring the shock is correctly set up for your specific riding requirements from day one.
Through-Rod Technology — Everyday Performance Gains
Unlike conventional twin-tube designs, the Through-Rod layout equalises pressure across both sides of the piston throughout the full stroke. The practical result is more linear damping response, reduced friction, and a shock that behaves predictably whether you are exploring a new circuit for the first time or chasing tenths on a familiar track. Because the design eliminates the need for an external reservoir, there is one less component to package, protect, or re-plumb if the shock is ever rebuilt.
Built for Racers on Real-World Budgets
K-Tech developed the TRDS-R explicitly for riders operating under series price caps or without full factory sponsorship — a category that covers the vast majority of club, national, and amateur endurance racers. The unit ships with recommended starting settings (13 mm preload, 18 compression clicks, 18 rebound clicks) so you are never starting from scratch, and the 4.00 mm of RCU adjustment range means there is meaningful scope to dial the chassis in as your pace and confidence grow.
