Proven in the British Superbike Championship and at the Isle of Man TT, this pressurised Direct Damping System replaces the standard cartridge with a sophisticated, cavitation-free unit that delivers consistent, nuanced control lap after lap.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e30-way independently adjustable compression and rebound damping for dial-in precision across every track surface and riding style\u003c\/li\u003e\n\u003cli\u003ePatented DDS (Direct Damping System) technology eliminates cavitation and maintains stable, reliable damping even under sustained high-speed stress\u003c\/li\u003e\n\u003cli\u003eAsymmetric, independent damping circuits sharpen response time and overall fork dynamics compared to a conventional cartridge\u003c\/li\u003e\n\u003cli\u003e20 mm piston paired with 31 mm control valves increases oil flow for smoother, more progressive damping feel\u003c\/li\u003e\n\u003cli\u003e8 mm piston rod minimises system offset and reduces unwanted flex in the damping stack\u003c\/li\u003e\n\u003cli\u003eIncreased stroke versus the original OEM cartridge, expanding the suspension travel window available to the rider\u003c\/li\u003e\n\u003cli\u003eRace-validated lineage — used in British Superbike and Isle of Man TT competition\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDirect Damping System Technology\u003c\/h2\u003e\u003cp\u003eThe DDS architecture pressurises the entire cartridge assembly, keeping the oil column consistently primed and free of air intrusion. Where a standard cartridge relies on a single damping circuit that can cavitate under hard braking or repeated high-frequency inputs, the K-Tech DDS unit uses spring-generated preload to hold the system at constant operating pressure. The result is damping that feels identical on the first corner of the day as it does on the last lap of a race.\u003c\/p\u003e\u003ch3\u003eAsymmetric Damping Circuits\u003c\/h3\u003e\u003cp\u003eBy separating the compression and rebound circuits entirely — the asymmetric, independent layout — K-Tech allows each side of the damping equation to be tuned without cross-contamination. Riders setting up for a specific circuit can adjust compression stiffness under braking without altering the rebound rate mid-corner, giving far greater granularity than a linked system allows.\u003c\/p\u003e\u003ch2\u003eSetup \u0026amp; Adjustment\u003c\/h2\u003e\u003cp\u003eThe kit ships with 3 pairs of springs to cover a wide range of rider weights and preferences, along with dedicated spring-change tools to make fork servicing straightforward. Recommended baseline settings are 16 compression clicks, 18 rebound clicks, and 10 mm of preload, giving a calibrated starting point for any track day or race weekend. The 18 mm preload adjustment range and 30-click damping range ensure there is sufficient scope to fine-tune from that baseline without reaching the limits of the system.\u003c\/p\u003e\u003cp\u003eFor optimal safety and to ensure the full performance capability of the kit is realised, installation by an authorised K-Tech Service Centre is strongly recommended.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis cartridge kit is designed specifically for the original fork of the Yamaha YZF-R6 in the following variants and model years:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eYamaha YZF-R6 RJ11 (2008–2010)\u003c\/li\u003e\n\u003cli\u003eYamaha YZF-R6 RJ15 (2008–2016)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003e155-011-270-010\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Series\u003c\/td\u003e\n\u003ctd\u003e36-260\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInner Diameter\u003c\/td\u003e\n\u003ctd\u003e20 mm \/ 32 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Diameter (piston rod)\u003c\/td\u003e\n\u003ctd\u003e8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e688 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompression Adjustment\u003c\/td\u003e\n\u003ctd\u003e30-way, recommended 16 clicks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRebound Adjustment\u003c\/td\u003e\n\u003ctd\u003e30-way, recommended 18 clicks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePreload Adjustment\u003c\/td\u003e\n\u003ctd\u003e18 mm range, recommended 10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eYamaha YZF-R6 RJ11, RJ15 (2008–2016)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"K-Tech","offers":[{"title":"Default Title","offer_id":53168847945994,"sku":"155-011-270-010","price":1714.59,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/DDS3_f16abfbb-8bae-4b2f-bef5-e41bfecd96df.png?v=1780817464","url":"https:\/\/inter-pace.com\/en-va\/products\/k-tech-dds-closed-cartridge-kit-yamaha-yzf","provider":"Inter-Pace","version":"1.0","type":"link"}
