DescriptionThe whole story

Unlock the full suspension potential of your Yamaha YZF-R7 with the K-Tech 25IDS Open Cartridge Kit — an independent damping system engineered specifically for the YZF-R7's original fork, giving you the precise, all-day comfort and confidence that the factory internals simply cannot match. Whether you ride long road miles or push hard on track, this kit transforms the R7's front end into something genuinely adjustable and responsive to your personal riding style.

Key Features

  • 25 mm Independent Damping System (25IDS) designed as a direct upgrade for the Yamaha YZF-R7 (2021-2026) original fork
  • 30 clicks of rebound adjustment and 24 clicks of compression adjustment for precise, rider-tailored damping
  • Increased stroke over the original fork internals, improving wheel tracking and comfort over varied road surfaces
  • Manufactured from aerospace-grade aluminium for an excellent strength-to-weight ratio and long service life
  • Hard-anodised and super-finished components for outstanding durability and reduced friction throughout the stroke
  • Suggested starting settings included — compression 14 clicks, rebound 18 clicks, preload 8 mm — so you can dial in your setup from the first ride

Performance and Build Quality

The 25IDS format separates rebound and compression circuits entirely, meaning each adjustment you make has a clean, predictable effect with no cross-interference. This independent architecture is what allows the K-Tech kit to offer such a wide, usable range across its click range — from compliant and comfortable on a long touring day to sharp and controlled when you want to explore the R7's chassis limits on a twisty road or a circuit. The aerospace-grade aluminium construction keeps unsprung weight in check while the hard-anodised super-finished surfaces ensure the damping rods move smoothly and consistently ride after ride, resisting wear far beyond standard OEM internals.

Road and Track Use

The 130 mm stroke and the carefully chosen internal geometry of this kit mean the fork maintains composure under braking, tracks surface imperfections without deflecting, and returns consistent feedback through the bars — qualities that matter just as much during an all-day touring run as they do on a fast circuit lap. The suggested click settings provide an excellent baseline, and the generous adjustment range means you can fine-tune from there without needing workshop tools or specialist knowledge between sessions.

Important Notes

Compatible springs from K-Tech's 36-260 series must be ordered separately — the cartridge kit does not include springs. Installation by an authorised K-Tech Service Centre is strongly recommended to ensure correct assembly, fluid fill and safety.

Fitment and Compatibility

This open cartridge kit fits the Yamaha YZF-R7 for model years 2021 through 2026. It is designed to work within the original fork legs without modification to the outer tubes.
