K-Tech 25IDS Open Cartridge Kit – Honda CBR 1000 RR-R SP SC82 (2020–2026) 130-020-130-020

Transform the everyday ride and track performance of your Honda CBR 1000 RR-R SP SC82 with the K-Tech 25IDS Open Cartridge Kit — a precision-engineered 25 mm Independent Damping System that puts genuine suspension tuning within reach of any rider, whether you use your SC82 for weekend road rides, track days, or both. Part number 130-020-130-020, this kit is designed specifically for the SP model (2020–2026) and delivers a level of adjustability that the standard cartridge simply cannot match.

Key Features

• 25 mm Independent Damping System (25IDS) allows rebound and compression to be tuned completely independently, so you can dial in a comfortable daily setup without compromising track-ready response.
• 30-click rebound adjustment and 24-click compression adjustment provide fine, repeatable steps — ideal for riders who want to experiment gradually rather than commit to a full rebuild.
• Increased travel compared to the original cartridge: 125 mm stroke gives a more progressive feel over road imperfections and greater control under hard braking on circuit.
• Aerospace-grade aluminium construction keeps weight low while providing the structural integrity demanded by the CBR 1000 RR-R SP's aggressive geometry.
• Hard-anodised and super-finished internal components reduce friction and wear, extending service intervals and keeping damping consistent across temperature ranges.
• Suggested baseline settings (compression 14 clicks, rebound 18 clicks, preload 10 mm) give you an immediate, usable starting point — no guesswork from scratch.

Build Quality & Performance

K-Tech's open cartridge design integrates directly into the Honda CBR 1000 RR-R SP SC82's existing fork legs, retaining the factory outer tubes while replacing the internals with components built to a far higher tolerance. The aerospace aluminium used throughout the kit is hard-anodised and then super-finished — a two-stage surface treatment that produces an exceptionally smooth bore, reduces stiction and ensures the damping response you set on the adjuster is precisely what reaches the wheel. The increased stroke of 125 mm over the original cartridge is a practical benefit on road use: it absorbs the kind of mid-corner bumps and surface changes that cause the stock setup to deflect, keeping the front tyre loaded and the rider confident. On track, that same extra travel translates into better feel under trail-braking and more consistent lap times.

Everyday Usability & Value

Unlike full bespoke suspension builds that require specialist dyno time and a significant budget, the 25IDS kit is engineered to be genuinely approachable. The 30-click rebound and 24-click compression ranges mean you can soften the package for a long motorway run, then firm it back up before a track evening — all with a flat-blade screwdriver and the supplied baseline figures as your reference. K-Tech's open cartridge philosophy also means the kit can be serviced, revalved and re-sprung as your riding evolves, making it a long-term investment rather than a one-time purchase. Springs are ordered separately (36-260 series), which allows you to match the rate precisely to your weight and riding style rather than accepting a compromise rate.

Fitment & Compatibility

This kit is designed exclusively for the Honda CBR 1000 RR-R SP SC82, model years 2020 through 2026 (SP variant). It is not compatible with the standard (non-SP) CBR 1000 RR-R. Matching springs from the K-Tech 36-260 series must be ordered separately. Installation by an authorised K-Tech Service Centre is recommended to ensure correct setup and to validate the baseline settings for your specific weight and riding profile.
