K-Tech 20IDS Open Cartridge Kit for Yamaha YZF-R3 (2019–2026) – 120-019-270-005

The K-Tech 20IDS Open Cartridge Kit transforms the front-end feel of the Yamaha YZF-R3, replacing the standard fork internals with a precision-engineered 20mm Independent Damping System built specifically for this chassis. Crafted from aerospace-grade aluminium with hard-anodised and super-finished components, this kit is a statement of K-Tech's suspension heritage — delivering race-calibre adjustability in a package that looks as purposeful as it performs.

Key Features

• 20mm Independent Damping System (20IDS) designed specifically for the original YZF-R3 fork legs
• 30 clicks of independent compression adjustment and 30 clicks of independent rebound adjustment for highly precise chassis tuning
• Increased stroke compared to the original cartridge, expanding the suspension's effective working range
• Aerospace-grade aluminium construction with hard-anodised and super-finished surfaces for exceptional durability and long service life
• Compatible with K-Tech's 32-340 spring series, allowing spring rate selection to be matched to rider weight and riding style
• Suggested setup baseline provided: compression 16 clicks, rebound 18 clicks, preload 18 mm

Design, Finish and Heritage

K-Tech Suspension has built its reputation at the highest levels of motorcycle sport, supplying teams across World Superbike, British Superbike and Moto2. The 20IDS Open Cartridge Kit carries that lineage directly into a road and trackday-legal format. Every component is machined to exacting tolerances and finished with hard anodising followed by a super-finish process, reducing friction at the cartridge walls and extending the service interval well beyond what standard fork internals can achieve. The result is a fork that responds consistently whether you are scrubbing speed into a hairpin or absorbing mid-corner bumps on a circuit infield section.

Performance and Adjustability

Independent compression and rebound circuits — each offering 30 clicks of adjustment — allow the two damping forces to be tuned in isolation. This is a significant step beyond single-adjuster or non-adjustable OEM cartridges, where changing one characteristic inevitably compromises the other. The increased stroke over the standard cartridge gives the suspension more travel to work with, which is particularly noticeable on aggressive road riding and trackday use where the front end is repeatedly loaded hard under braking. Preload is adjustable to set the static sag correctly for the individual rider's weight. Springs must be ordered separately from K-Tech's 32-340 series; selecting the correct spring rate is essential to realising the full benefit of the cartridge's damping range.

Fitment and Compatibility

This cartridge kit is designed and manufactured exclusively for the Yamaha YZF-R3 covering model years 2019 through to 2026. Installation by an authorised K-Tech Service Centre is recommended to ensure correct fitment, bleed procedure and baseline setup.
