K-Tech TRDS-R Closed Cartridge Kit – Suzuki GSX-R 1000 (2017–2023) – 160-017-230-025

Built for riders who measure success in lap times rather than comfort compromises, the K-Tech TRDS-R Closed Cartridge Kit transforms the front-end behaviour of the Suzuki GSX-R 1000 (2017–2023) into something race-ready from the first installation. Developed under the pressures of real competition — British Superbike, Isle of Man TT and beyond — this kit delivers the kind of precise, repeatable damping control that factory-supported teams take for granted, at a price point accessible to privateer racers and ambitious club competitors.

Key Features

• Through-Rod Damping System (TRDS-R) technology enables precise, individually tunable compression and rebound damping — the 'R' stands for Regulation, giving riders and technicians granular control over chassis behaviour.
• Compact closed-cartridge design improves heat dissipation significantly, maintaining consistent damping performance throughout a full race distance even under extreme conditions.
• 16 compression clicks and 16 rebound clicks (recommended baseline settings) provide a wide, finely stepped adjustment range to suit varying track surfaces, weather and rider style.
• 18 mm preload adjustment range allows spring rate optimisation without removing the forks, saving valuable setup time in the paddock.
• Proven at the highest level of international competition including British Superbike Championship and Isle of Man TT, making it a trusted choice for serious racers on a controlled budget.
• Supplied complete with a matched spring set, so the kit is ready to build straight out of the box.

Through-Rod Technology and Race Performance

The TRDS-R architecture replaces the conventional hollow damper rod with a solid through-rod design, which eliminates the pressure imbalance typically found in standard cartridge forks under high-speed damping loads. The result is a fork that responds predictably and linearly, whether you are braking hard into a chicane or riding over the crest of a mountain circuit. Because the system is self-contained within a closed cartridge, oil aeration is minimised and thermal stability is greatly improved — two factors that become critical after several laps of sustained high-speed riding.

Tuning and Setup Flexibility

K-Tech designed the TRDS-R specifically with resource-conscious race teams in mind. The 16-click compression and rebound adjusters can be dialled in track-side with nothing more than a flat-bladed screwdriver, and the 18 mm preload adjustment accommodates different spring rates for rider weight variation or circuit preference. The architecture also makes it straightforward for technicians to learn from and understand the fork's response, building genuine technical knowledge rather than relying on educated guesswork. K-Tech recommends installation by an authorised K-Tech Service Centre to ensure correct fitment and initial setup.
