DescriptionThe whole story

Contaminants entering the fork legs are one of the most insidious causes of suspension degradation — and on a machine as precisely engineered as the BMW M1000RR K66, that is a risk worth eliminating properly. The K-Tech DSS-026 dust seal kit uses NOK-manufactured seals sized to an exact fit for the M1000RR K66 from 2021 to 2026, blocking dirt and grime before they ever reach the oil seals beneath.

Key Features

  • Manufactured by NOK, one of the most trusted names in fork seal production for motorsport and premium road applications
  • Direct OEM-replacement fit for the BMW M1000RR K66 (2021-2026) — no modification or adaptation required
  • Precision inner diameter of 45.00 mm with dual outer diameters (58.30 mm and 62.30 mm) for correct seating in the fork leg
  • Dual-height profile (4.60 mm and 14.00 mm) replicates the original geometry to maintain fork action and sealing integrity
  • Prevents ingress of dust and road debris, prolonging the life of the oil seals and the fork internals
  • Supplied as a complete pair — both fork legs serviced in a single order

Build Quality and Suspension Protection

NOK is a globally respected manufacturer of sealing components for high-performance suspension, and K-Tech has specified their dust seals for this application precisely because the material compound holds its form under the thermal cycling and mechanical stress that track and road riding on the M1000RR demands. A degraded or missing dust seal allows abrasive particles to work against the fork stanchion and eventually compromise the oil seal below — leading to fork oil weeping and a measurable loss of damping consistency. Replacing these seals at regular service intervals is the simplest intervention to protect a far more expensive assembly.

Installation Note

These dust seals are designed specifically for the BMW M1000RR K66 (2021-2026) and should not be fitted to other models. Installation requires specialist tools and fork assembly knowledge. K-Tech recommends that fitting is carried out by an authorised K-Tech service centre to ensure performance and safety standards are fully maintained.
