DescriptionThe whole story

The K-Tech 25IDS Open Cartridge Kit transforms the factory fork of the BMW M1000RR K66 into a fully adjustable, precision-engineered suspension platform. Built around K-Tech's 25 mm Independent Damping System, this cartridge kit delivers the kind of setup control that serious road and track riders demand — with independent compression and rebound adjustment refined to 30 clicks each, leaving nothing to chance between the tyre and the road.

Key Features

  • 25 mm Independent Damping System (25IDS) engineered specifically for the BMW M1000RR K66 stock fork tubes
  • 30 clicks of independent compression adjustment and 30 clicks of independent rebound adjustment for precise, repeatable tuning
  • Increased travel compared to the original cartridge for improved wheel control across varied surfaces and track conditions
  • Aerospace-grade aluminium construction throughout, hard-anodised and super-finished for exceptional durability and reduced stiction
  • Installation by an authorised K-Tech Service Centre is recommended, ensuring correct setup and warranty validity
  • Compatible springs from the 36-260 series must be ordered separately — allowing the rider to select the exact spring rate for their weight and riding style

Engineering Detail

K-Tech has built the 25IDS around a philosophy of genuine independence: compression and rebound circuits are completely separate, meaning a change to one does not influence the other. This makes finding the optimal damping balance methodical rather than a game of compromise. The hard-anodised and super-finished surfaces on all critical components minimise internal friction, so the damping character you dial in on the clicker is exactly what reaches the wheel — not a blurred approximation.

The cartridge measures 717 mm in length with a 25 mm inner diameter and a 14 mm outer diameter, engineering a direct, high-quality replacement within the original fork legs. The 125 mm of travel represents a meaningful improvement over the standard unit. Suggested starting settings of 14 compression clicks, 18 rebound clicks, 8 mm preload, and a 135 mm oil/air cap height give any qualified technician a solid baseline from which to build a personalised setup.

Road and Track Use

Whether the M1000RR is used predominantly on track days or combines spirited road riding with occasional circuit sessions, the 25IDS kit provides the range of adjustment to suit both environments. Stiffer, more controlled damping for the circuit and a plusher, more compliant tune for the road are achievable without any hardware changes — simply count the clicks and record your settings.

Fitment and Compatibility

This cartridge kit fits the following motorcycle:

  • BMW M1000RR K66 (2021–2026)

Note: Matching springs from the 36-260 series are not included and must be ordered separately. Correct spring rate selection is essential for optimal performance.
