DescriptionThe whole story

Precision-engineered by K-Tech and manufactured by NOK — the seal supplier trusted by leading Japanese suspension manufacturers worldwide — this dust seals kit delivers a factory-correct fit and proven long-term protection for the forks of the Yamaha YZF-R6 RJ27. Where lesser aftermarket seals compromise over time, NOK's reputation for dimensional accuracy and material consistency makes the DSS-017 the natural choice for a lasting rebuild.

Key Features

  • Direct OEM replacement manufactured by NOK, trusted globally by premium suspension builders and used as original equipment by leading Japanese brands.
  • Precision dimensions — 43.00 mm inner diameter, 55.50 mm outer diameter — guarantee a flush, rattle-free seating in the RJ27 fork leg.
  • Dual-height profile (4.70 mm / 14.00 mm) replicates the original seal geometry for correct lip contact and consistent dust exclusion.
  • Supplied as a matched pair so both fork legs are serviced simultaneously with seals from the same production batch.
  • Keeps abrasive road and track debris away from the fork stanchions, extending the service life of oil seals, bushings and stanchion surfaces.

Heritage, Design and Finish

K-Tech Suspension has built its reputation on supplying components that meet or exceed the standards set by the original equipment manufacturers. The DSS-017 dust seal kit embodies that philosophy: NOK's manufacturing heritage spans decades of collaboration with the Japanese motorcycle industry, and every seal leaving the production line carries that legacy of tight tolerances and durable elastomer compounds. The result is a component that looks and behaves exactly as Yamaha intended — not a close approximation, but a genuine like-for-like replacement backed by one of the industry's most respected seal makers.

Performance and Longevity

Fork dust seals are the first line of defence against contamination. A degraded or poorly fitting dust seal allows fine grit and moisture to migrate toward the main oil seal, accelerating wear on stanchion coatings and shortening service intervals. By using a NOK-manufactured seal with the correct lip geometry and compound hardness, you restore that protective barrier fully, keeping fork action smooth and consistent whether the R6 is being used on the road or pushed hard on track.

Installation Notes

These dust seals are designed exclusively for the Yamaha YZF-R6 RJ27 built between 2017 and 2026. Fitment to other models or year ranges is not confirmed. K-Tech recommends that installation is carried out by an authorised K-Tech Service Centre to ensure correct seating, optimal performance and maintained safety standards.
