DescriptionThe whole story

Designed from the outset around all-day rideability, the K-Tech 20IDS Open Cartridge Kit transforms the stock forks of the Yamaha YZF-R3 into a fully adjustable, precision-tuned front end — whether you are threading through a morning commute or chasing lap times at the weekend. The 20mm Independent Damping System slots directly into the original fork legs, giving every rider genuine, independent control over compression and rebound without compromise.

Key Features

  • 20mm Independent Damping System (20IDS) engineered specifically for the YZF-R3 factory fork — a direct, clean installation with no fork-leg modifications required
  • 30 clicks of independent compression adjustment and 30 clicks of independent rebound adjustment for precise, repeatable damping tuning to suit any road surface or riding style
  • Increased travel compared to the original cartridge, expanding the fork's capability across a wider range of conditions
  • Aerospace-grade aluminium components throughout, hard-anodised and super-finished for exceptional durability and long service life
  • Suggested baseline settings provided (compression 16 clicks, rebound 16 clicks, preload 18 mm) so you can dial in comfort from the very first ride

All-Day Comfort Through Independent Damping

The real-world benefit of the 20IDS architecture is the freedom to tune compression and rebound entirely independently. On a standard cartridge these two forces are inherently linked, meaning any adjustment is a compromise. With the K-Tech 20IDS system you can soften the rebound to absorb fatigue on long motorway stretches, then add compression stiffness for a technical back road — all without upsetting the balance you have already found. The result is a front end that works with the rider rather than against them, hour after hour.

Build Quality and Materials

K-Tech has specified aerospace aluminium for every major structural component in this kit. Hard-anodising and a super-finished surface treatment on all critical wear surfaces reduce friction, resist corrosion and maintain consistent damping characteristics over the lifetime of the cartridge. The 35-340 spring series is compatible with this kit; springs must be ordered separately to allow riders to select the correct rate for their weight and intended use.

Fitment and Compatibility

This cartridge kit is designed and validated exclusively for the following application:

  • Yamaha YZF-R3 — model years 2015, 2016, 2017, 2018

Installation by an authorised K-Tech Service Centre is strongly recommended to ensure correct setup, baseline settings and warranty coverage.
