Every component is manufactured to tolerances that reflect the brand's heritage supplying professional Superbike teams. The closed cartridge format keeps the damping oil sealed and pressurised, preventing the aeration that causes conventional cartridge forks to fade under repeated hard braking and high-speed compression. The 31 mm control piston is a hallmark of the DDS design — its larger surface area relative to the working piston drives the asymmetric damping curve that makes the fork feel planted under braking yet supple over mid-corner bumps. This is not an upgrade built around a single specification; it is an adjustable system designed to be dialled in precisely for the rider, the machine, and the conditions.\u003c\/p\u003e\u003ch2\u003ePerformance on Road and Track\u003c\/h2\u003e\u003cp\u003eWith 30 clicks of compression and 30 clicks of rebound adjustment, the DDS kit covers everything from spirited road riding to full-circuit racing. The suggested baseline settings — 16 clicks compression, 18 clicks rebound, 10 mm preload, and a 165 mm oil\/air gap — provide a proven starting point from which riders can build a personalised setup. The 125 mm stroke and 690.25 mm cartridge length are matched precisely to the S1000RR fork internals for the 2009–2014 model years, ensuring correct travel and oil volume without modification.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis kit is designed exclusively for the BMW S1000RR across the following model years:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBMW S1000RR – 2009\u003c\/li\u003e\n\u003cli\u003eBMW S1000RR – 2010\u003c\/li\u003e\n\u003cli\u003eBMW S1000RR – 2011\u003c\/li\u003e\n\u003cli\u003eBMW S1000RR – 2012\u003c\/li\u003e\n\u003cli\u003eBMW S1000RR – 2013\u003c\/li\u003e\n\u003cli\u003eBMW S1000RR – 2014\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\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring series\u003c\/td\u003e\n\u003ctd\u003e36-260 series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInner diameter\u003c\/td\u003e\n\u003ctd\u003e20 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter diameter\u003c\/td\u003e\n\u003ctd\u003e32 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e690.25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOil \/ air gap (suggested)\u003c\/td\u003e\n\u003ctd\u003e165 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStroke\u003c\/td\u003e\n\u003ctd\u003e125 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompression clicks (suggested)\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRebound clicks (suggested)\u003c\/td\u003e\n\u003ctd\u003e18\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePreload\u003c\/td\u003e\n\u003ctd\u003e10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003e155-011-030-020\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"K-Tech","offers":[{"title":"Default Title","offer_id":53168815145226,"sku":"155-011-030-020","price":1714.59,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/DDS3.png?v=1780816348","url":"https:\/\/inter-pace.com\/en-mg\/products\/k-tech-dds-closed-cartridge-kit-bmw-s1000rr","provider":"Inter-Pace","version":"1.0","type":"link"}
