DescriptionThe whole story▼
Designed for riders who demand race-level suspension control without the overhead of factory team support, the K-Tech TRDS-R shock absorber delivers championship-proven performance on the BMW S1000RR K67. Its through-rod architecture and 'Regulation' tuning philosophy make it equally at home on a Sunday trackday, a British Superbike grid, or the Isle of Man TT course.
Key Features
- Through-rod damper technology provides precise, repeatable damping characteristics and superior heat dissipation — no external reservoir required, keeping installation clean and compact.
- The 'R' (Regulation) specification enables high-precision adjustment to improve lap times, making it accessible even to riders without full factory sponsorship backing.
- 18-click compression and 18-click rebound adjustment (suggested baseline) give technicians and amateur riders alike a wide, clearly defined tuning range.
- A generous 4.00 mm of RCU adjustment travel allows meaningful setup changes to be dialled in quickly between sessions.
- Proven at the highest levels of British Superbike and the Isle of Man TT, the TRDS-R carries real-world race pedigree to the road and track.
- Direct fitment for the BMW S1000RR K67 (2019–2026) — no modifications or adaptors needed.
Performance Without Compromise
The compact, self-contained design of the TRDS-R eliminates the packaging and plumbing complexity of traditional reservoir units. By routing the damping rod through the full length of the piston, K-Tech's through-rod system equalises pressure on both sides of the piston, resulting in consistent, fade-free damping across extended stints. Heat — the enemy of suspension performance on long circuits like the Isle of Man — is dissipated efficiently through the unit's body, maintaining a predictable feel lap after lap.
Everyday Usability and Value
While the TRDS-R competes at world-class level, its Regulation-grade tuning range is specifically calibrated to reward riders who are developing their setup knowledge incrementally. The suggested starting points for compression, rebound and preload mean you can be riding with a sensible baseline from the moment it is fitted, then refine from there. For club racers, track-day regulars and road riders upgrading from the standard BMW unit, this represents a straightforward, cost-effective step to genuinely better chassis feedback. Installation by an authorised K-Tech Service Centre is recommended to ensure the unit is correctly set up for your riding weight and style.
