Whether you are threading through traffic or threading the needle at a circuit, the Direct Damping System keeps the front end settled and responsive without ever asking you to compromise between comfort and control.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e30-way independently adjustable compression and rebound damping for a setup that suits your exact riding style and conditions\u003c\/li\u003e\n\u003cli\u003e18 mm preload adjustment range allows precise spring loading to match rider weight and road surface\u003c\/li\u003e\n\u003cli\u003ePatented DDS (Direct Damping System) technology actively prevents cavitation, ensuring consistent damping force across the full stroke\u003c\/li\u003e\n\u003cli\u003eAsymmetric, independently operating damping circuits reduce response lag and sharpen front-end dynamics\u003c\/li\u003e\n\u003cli\u003e20 mm piston paired with 31 mm control valves promotes optimised oil flow and finer damping resolution\u003c\/li\u003e\n\u003cli\u003e8 mm piston rod minimises system offset for a more linear, predictable feel\u003c\/li\u003e\n\u003cli\u003eIncreased travel compared to the original cartridge, giving the fork greater compliance over rough surfaces\u003c\/li\u003e\n\u003cli\u003eRace-proven in the British Superbike Championship and the Isle of Man TT\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAll-Day Comfort Through Precision Engineering\u003c\/h2\u003e\u003cp\u003eA cartridge upgrade is often thought of as a pure track tool, but the K-Tech DDS is equally transformative on the road. The asymmetric damping circuits work independently, so compression and rebound events are handled separately rather than as a compromise. The result is a fork that absorbs successive bumps without building up harshness — the kind of progressive, consistent feel that keeps your hands fresh and your shoulders relaxed on long rides. The 30-way click adjustment means you can dial in a softer, more pliant character for touring without sacrificing the crispness needed when the road opens up.\u003c\/p\u003e\u003ch2\u003eTrack Performance\u003c\/h2\u003e\u003cp\u003eOn circuit, the DDS design comes into its own. Cavitation — the formation of air bubbles in the damper oil under rapid successive compression — is the enemy of consistent lap times, because it causes the fork to feel progressively softer as a session goes on. K-Tech's patented closed cartridge architecture eliminates this by maintaining a sealed, pressurised oil circuit. Combined with the 31 mm control piston and the spring-loaded stability mechanism, the system delivers repeatable lap-to-lap performance whether you are at Brands Hatch or battling the Mountain Course.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis kit fits directly into the original forks of the Kawasaki ZX-6R 636 for all model years from 2013 to 2026. No fork tube modification or external reservoir routing is required — the closed cartridge design integrates cleanly within the existing fork leg architecture.\u003c\/p\u003e\u003cp\u003eInstallation by an authorised K-Tech Service Centre is strongly recommended to ensure correct assembly, oil fill, and setup, and to achieve the full safety and performance potential of the system.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSpring series: 36-260\u003c\/li\u003e\n\u003cli\u003eInner diameter: 20 mm \/ 32 mm\u003c\/li\u003e\n\u003cli\u003eOuter diameter (piston rod): 8 mm\u003c\/li\u003e\n\u003cli\u003eCompression clicks (recommended setting): 16\u003c\/li\u003e\n\u003cli\u003eRebound clicks (recommended setting): 18\u003c\/li\u003e\n\u003cli\u003ePreload (recommended setting): 10 mm\u003c\/li\u003e\n\u003cli\u003ePreload adjustment range: 18 mm\u003c\/li\u003e\n\u003cli\u003eCompression \/ rebound adjustment: 30-way\u003c\/li\u003e\n\u003cli\u003ePart number: 155-013-150-015\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"K-Tech","offers":[{"title":"Default Title","offer_id":53168835821834,"sku":"155-013-150-015","price":2040.36,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/DDS3_d67c85f1-ef8c-4a9e-9d44-83d9b074716b.png?v=1780817080","url":"https:\/\/inter-pace.com\/products\/k-tech-dds-closed-cartridge-kit-kawasaki-zx","provider":"Inter-Pace","version":"1.0","type":"link"}
