K-Tech 25IDS Open Cartridge Kit for Yamaha YZF-R6 RJ27 (2017–2026) – 130-017-270-010

Engineered around K-Tech's heritage in precision suspension development, the 25IDS Open Cartridge Kit transforms the stock forks of the Yamaha YZF-R6 RJ27 (2017–2026) into a fully tuneable, race-derived damping platform. Hard-anodised aerospace aluminium construction gives this kit the kind of finish and structural integrity that reflects K-Tech's decades of motorsport pedigree — built to look as purposeful as it performs.

Key Features

• 25mm Independent Damping System (25IDS) designed to retrofit directly into the original YZF-R6 fork legs, retaining OEM fitment integrity
• 30-click rebound adjustment and 24-click compression adjustment for exceptional precision across a wide tuning range
• Increased travel over the standard unit delivers improved suspension performance and compliance
• Aerospace-grade aluminium with hard-anodised finish for long service life and resistance to wear under demanding conditions
• Recommended baseline settings included to get you dialled in from the first ride
• Compatible with K-Tech 36-260-series springs (sold separately)

Design, Finish and Heritage

K-Tech Suspension has built its reputation supplying suspension components at the highest levels of road racing, and the 25IDS cartridge kit carries that lineage directly into your R6's forks. The hard-anodised aerospace aluminium components are not merely a finish choice — they represent a material commitment to durability and dimensional stability under repeated thermal and mechanical cycling. Every click of the adjuster is crisp and positive, reflecting the tight manufacturing tolerances that define K-Tech's production standards.

The open cartridge architecture allows independent adjustment of rebound and compression damping, meaning changes you make to one circuit do not compromise the other. This independence is central to the 25IDS philosophy and is what separates it from budget cartridge conversions.

Performance and Tunability

With 30 clicks of rebound and 24 clicks of compression adjustment available, the 25IDS system provides a tuning envelope wide enough to accommodate everything from spirited road riding to track day use. The increased stroke over the original fork internals broadens the suspension's working range, allowing it to manage both small, high-frequency surface imperfections and larger compressions with greater composure. Suggested baseline settings — 14 clicks compression, 18 clicks rebound, 8 mm preload — give you a proven starting point before you begin dialling to your riding style and preferred circuit.

Fitment and Compatibility

This cartridge kit is designed specifically for the Yamaha YZF-R6 RJ27 covering model years 2017 to 2026. It is engineered to install into the original fork tubes without modification to the fork legs themselves. K-Tech recommends installation by an authorised K-Tech Service Centre to ensure correct setup and to protect the integrity of the system. Compatible springs from the K-Tech 36-260 series must be ordered separately.
