K-Tech 25IDS Open Cartridge Kit for Yamaha YZF-R6 (2008–2016) – 125-011-270-010

Unlock genuinely adjustable fork performance on your Yamaha YZF-R6 without replacing the entire front end. The K-Tech 25IDS Open Cartridge Kit slots into the original fork legs and gives everyday riders and track-day enthusiasts alike a straightforward, cost-effective route to independent rebound and compression control — dialled in for your weight, your roads and your riding style.

Key Features

• 25mm Independent Damping System (25IDS) designed specifically for the Yamaha YZF-R6 (2008–2016) stock fork
• 24 independent compression clicks and 30 independent rebound clicks for precise, repeatable damping adjustment
• Increased travel compared to the original cartridge, improving suspension response across a wider range of conditions
• Aerospace-grade aluminium construction with hard-anodised, super-finished surfaces for long service life and reduced friction
• Wide range of compatible 36-260 series springs available separately — tune the spring rate to suit your exact weight and use case
• Suggested baseline settings included (14 compression clicks, 18 rebound clicks, 8 mm preload) so you can ride immediately and refine from there

Everyday Usability and Value

Where a full fork replacement demands a serious budget and specialist fitting, the 25IDS Open Cartridge Kit delivers the core of what makes a great fork — independent damping adjustment and a quality working surface — at a fraction of the cost. The suggested click settings mean you are not starting from scratch: mount the kit, set the baseline, and feel the difference on your very first ride. Whether you commute through city traffic on weekdays and chase lap times at the weekend, the wide adjustment range covers both worlds without compromise.

Build Quality

K-Tech machines the cartridge bodies from high-grade aerospace aluminium and subjects every sliding surface to a hard-anodising and super-finishing process. The result is a surface that is harder than steel, resists scoring from contaminants, and maintains consistent damping force throughout the stroke — even after extended use. The 25 mm internal diameter and 688 mm overall length are engineered to match the YZF-R6 fork geometry precisely, eliminating the shimming and adaptor work that generic kits often require.

On the Road and Track

The 125 mm of travel gives a useful margin over the standard cartridge, translating to better composure under hard braking and improved traction feel mid-corner. Independent compression and rebound circuits mean softening the rebound for a long motorway stint does not force you to sacrifice braking stability — each characteristic is tuned on its own terms. When you return to the track, winding in compression clicks stiffens the fork for high-speed direction changes without upsetting the rebound behaviour you already have set.

Fitment and Compatibility

This cartridge kit fits the following model directly, using the original fork tubes:

• Yamaha YZF-R6 — model years 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016

Springs are not included and must be ordered separately from the K-Tech 36-260 series range. Installation by an authorised K-Tech Service Centre is recommended to ensure correct pre-load setting and oil volume.
