DescriptionThe whole story▼

The Öhlins NIX 30 Cartridge Kit FGK 240 is a precision-engineered fork upgrade built specifically for the BMW M1000RR K66, transforming factory fork performance through Öhlins' acclaimed 30 mm cartridge technology. Machined to exacting tolerances and finished to the standards that have made Öhlins the benchmark in racing suspension, this kit delivers a measurable step forward in damping consistency and front-end stability whether you are pushing hard on track or covering fast road miles.

Key Features

  • 30 mm cartridge system engineered for the BMW M1000RR K66 — superior damping control compared to stock internals, with noticeably improved high-speed stability.
  • Compression damping and compression adjuster housed in the left fork leg; rebound damping and rebound adjuster integrated into the right leg — a clean, logical layout that makes trackside tuning intuitive.
  • All adjustments, including spring preload, are accessible at the fork cap — no need to remove the fork legs for a baseline setup change.
  • 120 mm of travel maintained from the original fork architecture, preserving steering geometry while dramatically improving damping quality.
  • ABE certification (Germany) included, confirming road-legal fitment on the German market without the need for additional homologation.
  • Installation guide included; professional fitment at an authorised Öhlins Service Centre is recommended for optimal results.

Build Quality and Premium Materials

The FGK 240 reflects everything Öhlins stands for in premium suspension engineering. The cartridge components are manufactured from high-grade materials selected for their stiffness-to-weight ratio and long-term durability under repeated high-load cycling. Internal tolerances are held to levels that ensure consistent oil flow and damping response across the full stroke — the kind of precision that separates a genuine performance upgrade from an aftermarket approximation. The result is a fork that communicates tyre contact and chassis attitude with clarity, giving the rider the confidence to push their M1000RR harder and later.

Track and Road Performance

On the circuit, the NIX 30 system addresses one of the most common criticisms of high-powered superbike forks: inconsistent damping under repeated braking and corner-entry loads. By separating compression and rebound circuits into dedicated fork legs, Öhlins eliminates cross-talk between the two functions and allows each to be tuned independently without compromise. On the road, the same architecture translates to a fork that remains composed over surface changes and braking events where the stock unit can feel vague or overwhelmed. The accessible adjuster positions mean that moving between road and track settings takes minutes, not a workshop session.
