DescriptionThe whole story▼
Engineered for riders who demand the highest level of chassis precision, the K-Tech 25IDS Open Cartridge Kit with +15mm extended top caps transforms the front-end behaviour of the Yamaha YZF-R1 (2015–2026). Built around K-Tech's proven 25mm Independent Damping System, this kit is recommended for installation by an authorised K-Tech Service Centre, ensuring every component is set up to the exacting standards the system requires.
Key Features
- 25mm Independent Damping System (25IDS) delivers independently adjustable compression and rebound circuits for precise, repeatable chassis tuning
- +15mm extended top caps increase stroke over the standard design, directly improving suspension travel and front-end response
- 30-click compression adjustment and 30-click rebound adjustment provide a wide, finely graduated tuning range to suit road and track conditions
- Aerospace-grade aluminium construction with hard-anodised and super-finished surfaces for long service life and consistent damping characteristics
- Manufacturer-suggested baseline settings (compression 14 clicks, rebound 18 clicks, preload 8 mm) get you on track quickly from the first session
- Installation by an authorised K-Tech Service Centre is recommended to safeguard performance and longevity
Performance & Build Quality
The 25IDS architecture isolates the compression and rebound circuits, allowing each to be dialled independently without affecting the other — a fundamental advantage over conventional cartridge designs when fine-tuning mid-corner stability or braking feel. The hard-anodised and super-finished internal components minimise stiction and ensure the damping response remains consistent across temperature and load variations, whether you are chasing lap times at a circuit or managing variable surfaces on the road.
The +15mm increase in top cap length raises the cartridge position within the fork leg, delivering additional usable stroke compared to the standard configuration. Combined with the correct spring from K-Tech's 36-260 series (sold separately), this translates to a more progressive, controllable feel at the limit.
Setup & Installation
Matching springs from the K-Tech 36-260 series must be ordered separately to complete the front suspension build. K-Tech strongly recommends installation by an authorised K-Tech Service Centre to ensure correct assembly, bleeding and baseline adjustment — a requirement that protects both the investment and the rider. The suggested starting clicks (compression 14, rebound 18, preload 8 mm) are validated for the YZF-R1 platform and form a solid baseline for further track-day refinement.
