DescriptionThe whole story

Designed from the ground up for the Triumph Street Triple 765 RS, the K-Tech 25IDS Open Cartridge Kit transforms the standard fork into a fully adjustable, race-derived suspension platform that rewards long days in the saddle and back-to-back track sessions alike. Whether you are chasing cornering confidence on a winding B-road or dialling in lap times, this cartridge kit gives you the independent control to make the ride feel effortlessly right.

Key Features

  • 25 mm Independent Damping System (25IDS) engineered specifically for the Street Triple 765 RS factory fork — a direct, precision fit that eliminates guesswork
  • 24-click independent compression adjustment and 30-click independent rebound adjustment deliver exceptionally fine tuning resolution for every rider weight, road surface and riding style
  • Increased stroke over the original cartridge for improved suspension travel and a more planted, controlled feel through transitions
  • Aerospace-grade aluminium construction combined with hard-anodised and super-finished components for outstanding durability and long-term performance consistency
  • Wide range of compatible springs available (36-260 series) — order separately to match your exact weight and riding requirements
  • Part number 125-017-250-010 — installation by an authorised K-Tech Service Centre is recommended

All-Day Comfort and Adjustability

The 25IDS architecture separates compression and rebound circuits completely, which means you can soften the fork for long motorway stretches or firm it up for spirited riding without one adjustment compromising the other. With suggested starting points of 12 clicks compression, 18 clicks rebound and 8 mm preload, setup is straightforward even for riders new to fully adjustable suspension. From there the 24-click and 30-click ranges give you the granularity to refine the feel mile by mile until the Street Triple feels like a natural extension of your body.

Build Quality and Materials

K-Tech manufactures the 25IDS cartridge from aerospace-grade aluminium billet, then hard-anodises every critical surface and applies a super-finish treatment to the sliding components. The result is a friction-reducing, corrosion-resistant assembly that maintains consistent damping characteristics across a wide temperature range — from cold morning commutes to sustained track sessions. The extended stroke of 125 mm over the original cartridge design means the fork can absorb larger inputs without running out of travel, keeping the wheel in contact with the road surface and the rider comfortable over imperfect tarmac.
