DescriptionThe whole story▼
Engineered for riders who demand uncompromising fork performance, the K-Tech DDS Closed Cartridge Kit transforms the front-end feel of the Honda CBR 1000 RR across the full 2012–2019 model range. Built around K-Tech's patented Direct Damping System, this closed cartridge unit combines a 20 mm piston with a 31 mm control piston to deliver exceptional oil flow, near-instantaneous response, and the kind of consistent damping stability that has earned it a place at the sharp end of the British Superbike Championship and the Isle of Man TT.
Key Features
- Patented DDS (Direct Damping System) design actively eliminates cavitation, maintaining precise damping even under the most aggressive braking and corner-entry loads.
- Dual-piston architecture — 20 mm main piston paired with a 31 mm control piston — maximises oil flow and dramatically reduces response lag compared to conventional cartridge designs.
- 30-click independent compression and rebound adjustment lets you dial in the exact damping character your riding style and circuit demands.
- 18 mm preload adjustment range provides a wide window for fine-tuning spring sag and front-end geometry without swapping springs.
- Factory-suggested baseline settings (compression 16 clicks, rebound 18 clicks, preload 10 mm) give a strong starting point straight out of the box.
- Race-proven at British Superbike Championship and Isle of Man TT level — the same hardware available to privateer and club racers.
Build Quality and Materials
K-Tech manufactures the DDS Closed Cartridge Kit to tolerances demanded by professional motorsport. The cartridge body — outer diameter 32 mm — is machined to precise dimensions, while the internal components are finished to standards that prevent the micro-bubbling and cavitation that degrade damping consistency at high shaft speeds. The 36-260 series spring specification is matched to the cartridge's 690 mm operating length, ensuring the entire assembly works as a coherent, tuned unit rather than a collection of off-the-shelf parts. Every component reflects K-Tech's philosophy that suspension hardware for the road or the racetrack should be built without compromise.
Performance on Road and Track
The Direct Damping System architecture separates high- and low-speed damping circuits far more effectively than a conventional open cartridge, meaning the fork responds differently — and correctly — whether you are absorbing a mid-corner bump at 160 mph or trail-braking deep into a hairpin. The 30-click compression and rebound adjusters are accessible at the top of each leg, allowing trackside setup changes in seconds. For road riders, the same breadth of adjustment tames motorway expansion joints and urban imperfections without sacrificing the precision that makes the CBR 1000 RR such a rewarding machine to push.
