DescriptionThe whole story▼

Sealing integrity at the front fork is a genuine safety matter — a weeping fork leg contaminates the brake disc and compromises stopping power. The K-Tech FSK-007 fork oil seal and dust cover kit for the Honda CBR 600 RR (2007–2025) addresses that risk with NOK-manufactured seals, the same supplier trusted by motorcycle OEMs worldwide for first-fit quality. Correct dimensions, correct compounds, correct protection — from street commuting to circuit sessions.

Key Features

  • NOK-manufactured oil seals: a globally recognised OEM-grade seal supplier, chosen for exceptional dimensional accuracy and long service life
  • Complete kit containing two oil seals and two dust covers — everything needed for a full front fork service in one part number
  • Dust covers shield the fork stanchions and seal lips from road grit, mud and moisture, dramatically extending seal longevity
  • Precise 41 mm inner diameter / 54 mm outer diameter specification ensures a secure, leak-free fit in the CBR 600 RR fork leg
  • Prevents fork oil loss that would otherwise degrade suspension performance and create a brake-contamination hazard

Build Quality & Safety Rationale

NOK is not a generic aftermarket name. The company supplies original-equipment seals to major motorcycle manufacturers and is held to production tolerances that many aftermarket alternatives simply cannot match. Each seal in this kit is engineered to retain fork oil under the cyclic pressure and heat generated by repeated compression and rebound, while the dust cover above it acts as the first line of defence, keeping abrasive particles away from the seal lip entirely. Using OEM-grade components here is not a luxury — it directly supports predictable suspension behaviour and safe braking.

Installation Guidance

Fork seal replacement requires the fork legs to be removed, disassembled and refilled with fresh oil. K-Tech recommends installation by an authorised K-Tech Service Centre. Specialist tools and professional technique are necessary to ensure correct seating, proper oil fill level and optimal functionality. Attempting the job without the appropriate tools risks seal damage, oil leaks and compromised ride safety.

Fitment & Compatibility

This kit is designed specifically for the Honda CBR 600 RR across the entire production run from 2007 to 2025. Always confirm your fork inner diameter of 41 mm before fitting to ensure correct application.
