Built around K-Tech's patented Direct Damping System, every component in this kit reflects the exacting standards proven at the British Superbike Championship and the Isle of Man TT.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e30-way independently adjustable compression and rebound damping for precise, rider-specific chassis setup\u003c\/li\u003e\n\u003cli\u003ePatented DDS (Direct Damping System) design eliminates cavitation and maintains consistent, predictable damping even under the harshest race conditions\u003c\/li\u003e\n\u003cli\u003e20 mm piston and 31 mm control valves optimise oil flow for a finer feel and faster response across the full stroke\u003c\/li\u003e\n\u003cli\u003eAsymmetric, independently operating damping circuits improve dynamics and reaction time over a conventional cartridge\u003c\/li\u003e\n\u003cli\u003eIncreased stroke compared to the original factory cartridge — more travel, more control\u003c\/li\u003e\n\u003cli\u003ePressurised spring force keeps the system stable at all times, preventing fade or inconsistency mid-corner\u003c\/li\u003e\n\u003cli\u003eFully approved for Superstock 1000 classes — race-legal straight from the box\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Materials\u003c\/h2\u003e\u003cp\u003eThe DDS Closed STK kit is a testament to what happens when racing engineering meets meticulous manufacturing. The 8 mm piston rod minimises system offset and reduces flex under hard braking loads, while the tight tolerances across the 20 mm piston and 31 mm control valves ensure that the hydraulic circuit behaves exactly as intended lap after lap. The cartridge is designed as a direct replacement for the OEM unit inside the S1000RR K67 fork leg, requiring no modification to the fork tube itself. The result is a thoroughly race-tested assembly whose dimensional integrity holds up whether you are setting lap records at Brands Hatch or carrying race pace over the mountain at the TT.\u003c\/p\u003e\u003ch2\u003ePerformance on Road and Track\u003c\/h2\u003e\u003cp\u003eWith 30 clicks of adjustment on both compression and rebound, and an 18 mm preload range, the DDS Closed STK gives riders and technicians a genuinely wide tuning window. The recommended baseline settings — 16 compression clicks, 18 rebound clicks, 10 mm preload, and a 175 mm oil\/air cushion — provide an excellent starting point from which precise fine-tuning can be dialled in for individual track surfaces or rider preference. The increased stroke over the standard cartridge translates directly into improved feedback and composure over kerbs and mid-corner bumps, where the original unit can run out of travel. Three pairs of springs are included to cover a broad rider weight range, allowing setup to be optimised without sourcing additional components.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis cartridge kit is designed and validated specifically for the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBMW S1000RR K67 — model years 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eInstallation must be carried out exclusively by an authorised K-Tech Service Centre to ensure maximum safety and full performance.
