The 25 mm Independent Damping System separates compression and rebound circuits entirely, giving the rider a level of setup resolution that simply is not possible with a standard cartridge.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e25 mm Independent Damping System (25IDS) — compression and rebound are tuned independently for true, interference-free setup changes\u003c\/li\u003e\n\u003cli\u003e24 clicks of independent compression adjustment and 30 clicks of independent rebound adjustment for fine-grained control across a wide range of conditions\u003c\/li\u003e\n\u003cli\u003eIncreased stroke versus the original cartridge (+15 mm), unlocking greater chassis balance and improved front-end feel\u003c\/li\u003e\n\u003cli\u003eAerospace-grade aluminium construction throughout, hard-anodised and super-finished for exceptional durability and reduced friction\u003c\/li\u003e\n\u003cli\u003eCompatible with the full K-Tech 36-260 spring range, allowing the spring rate to be matched precisely to rider weight and riding style (springs sold separately)\u003c\/li\u003e\n\u003cli\u003ePart number 125-012-230-021 — traceable, genuine K-Tech fitment for the GSX-R 1000 2012–2023\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Materials\u003c\/h2\u003e\u003cp\u003eK-Tech manufactures the 25IDS cartridge body from aerospace-specification aluminium alloy, then hard-anodises every component to produce a surface that resists wear, corrosion and the thermal cycling that is unavoidable in hard track or road use. The super-finished bore and rod surfaces minimise stiction, ensuring the damping curves you dial in are the ones the fork actually delivers — lap after lap, not just on the first outing. Every tolerance is held to the standard K-Tech applies to its World Superbike-supplied components, making this kit a genuinely race-derived upgrade rather than a bolt-on compromise.\u003c\/p\u003e\u003ch2\u003eSetup and Performance\u003c\/h2\u003e\u003cp\u003eThe heart of the 25IDS design is the separation of the compression and rebound valving stacks. On a conventional cartridge, adjusting one circuit influences the other; the IDS architecture eliminates that interaction. The compression adjuster offers 24 distinct clicks, the rebound adjuster 30, so the rider can map damping response precisely to tyre compound, track surface and riding style. Suggested baseline settings — 12 clicks compression, 18 clicks rebound, 8 mm preload — provide a practical starting point from which setup work can begin immediately. The extended stroke of 125 mm, 15 mm more than the stock cartridge, allows the chassis to work through its full geometry range, improving stability under braking and feedback through corners.\u003c\/p\u003e\u003ch2\u003eImportant Notice\u003c\/h2\u003e\u003cp\u003eThe 25IDS Open SBK kit is not homologated for Superstock 1000 class competition. The increased travel of +15 mm places the fork outside the regulations for that category. Riders competing in Superstock should consult K-Tech's Superstock-legal alternatives. For all other track and road applications, installation by an authorised K-Tech Service Centre is strongly recommended to ensure correct setup and warranty validity. Compatible fork springs from the 36-260 series must be ordered separately.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis cartridge kit is designed and validated for the following fitment:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eSuzuki GSX-R 1000 — model years 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003e125-012-230-021\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInner diameter\u003c\/td\u003e\n\u003ctd\u003e25 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter diameter\u003c\/td\u003e\n\u003ctd\u003e14 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLength\u003c\/td\u003e\n\u003ctd\u003e659.25 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\u003e12\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 (suggested)\u003c\/td\u003e\n\u003ctd\u003e8 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring series\u003c\/td\u003e\n\u003ctd\u003e36-260 (sold separately)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"K-Tech","offers":[{"title":"Default Title","offer_id":53168842604810,"sku":"125-012-230-021","price":1180.82,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/25IDS_Piston_3690faac-0ea5-4c8b-a90c-55aa466ade4f.png?v=1780817215","url":"https:\/\/inter-pace.com\/products\/k-tech-25ids-open-sbk-cartridge-kit","provider":"Inter-Pace","version":"1.0","type":"link"}
