DescriptionThe whole story

Precision-engineered by K-Tech, this fork oil seal and dust cap kit for the Honda CBR 1000 RR (2004–2019) represents the definitive OEM-quality replacement solution — built around NOK seals, the same trusted supplier chosen by Japan's leading motorcycle manufacturers as original equipment. Where heritage and meticulous engineering meet, this kit restores your forks to factory-fresh performance.

Key Features

  • NOK oil seals fitted as original equipment by major Japanese motorcycle manufacturers — a benchmark of quality and longevity.
  • Complete kit includes two oil seals and two dust caps, covering both fork legs in a single purchase.
  • Precision dimensions (43.00 mm inner diameter, 54.00 mm outer diameter) ensure a correct, leak-free fit without modification.
  • Dust caps provide effective protection against dirt, dust and moisture, preserving fork internals and extending service intervals.
  • Spans the full 2004–2019 CBR 1000 RR production run, covering Fireblade generations from the SC57 through to the SC77.
  • K-Tech part number FSK-015 for straightforward identification and ordering.

Design, Finish and Heritage

K-Tech Suspension has built its reputation across World Superbike, BSB and club racing by supplying components that meet the exacting demands of professional teams. The FSK-015 kit reflects that same philosophy: every seal is sourced from NOK, a manufacturer whose long-standing partnerships with Honda, Yamaha and Kawasaki as an OE supplier speak to a standard of dimensional accuracy and material integrity that aftermarket alternatives rarely match.

The oil seals are manufactured to exact tolerances, ensuring the correct interference fit within the fork outer tube. The matching dust caps complete the assembly, forming the first line of defence against the abrasive road and track contamination that accelerates fork wear. Together, they maintain the hydraulic integrity that keeps your Fireblade's suspension tracking precisely through corners.

Performance on Road and Track

Worn or weeping fork seals are among the most common causes of degraded front-end feel — oil contamination on the brake disc is a safety critical consequence that no rider should ignore. Replacing seals with a quality NOK kit restores consistent damping characteristics, eliminates the telltale oil film on the inner tube and returns the fork to its designed performance envelope, whether you are carving twisty roads or chasing lap times.

Fitment & Compatibility

This kit fits the Honda CBR 1000 RR across all model years from 2004 to 2019, encompassing the following generations:

  • Honda CBR 1000 RR (SC57) – 2004 to 2007
  • Honda CBR 1000 RR (SC59) – 2008 to 2016
  • Honda CBR 1000 RR / SP / SP2 (SC77) – 2017 to 2019

If you are unsure whether this kit suits your specific variant, please verify your fork outer tube inner diameter (43.00 mm) before ordering.
