DescriptionThe whole story▼

Precision-engineered from the ground up, the K-Tech FSK-015 fork oil seal and dust cap kit brings NOK-manufactured seals to the Kawasaki ZX-10 R and ZX-10 RR — the same seal supplier trusted by leading Japanese OEM manufacturers. Where inferior aftermarket kits cut corners on compound quality, this kit matches and often exceeds the durability of the original fitment, keeping your forks leak-free and performing exactly as intended across the full 2011–2026 model range.

Key Features

  • NOK-manufactured oil seals — one of the most respected seal producers in suspension engineering, delivering exceptional material integrity and service life.
  • Matched dust caps included, forming a complete barrier against dirt, moisture and road debris that would otherwise accelerate fork tube wear.
  • Precise 43.00 mm inner diameter and 54.00 mm outer diameter ensure a correct, rattle-free fit in the ZX-10 R and ZX-10 RR fork legs.
  • Full kit format — both seals and both dust caps supplied together, so the job is completed in a single service session with no separate part sourcing required.
  • Covers the entire ZX-10 R and ZX-10 RR production run from 2011 through to 2026, making this the definitive replacement kit for this platform.

Build Quality & Materials

The quality of a fork seal kit is defined entirely by the compound from which it is made. K-Tech have specified NOK seals for the FSK-015 because the manufacturer's proprietary rubber formulations maintain elasticity across a wide temperature range, resist hydraulic oil degradation, and retain their sealing lip geometry through thousands of compression cycles. This is the standard that separates a kit you replace once from one you replace repeatedly. The dust caps complement this by providing a physical shield that keeps abrasive particles well away from the sealing surfaces — a detail that pays dividends on both road and track use where contamination risk is highest.

Performance & Longevity

A weeping fork seal is not merely an inconvenience — fork oil on the brake disc is a serious safety hazard, and degraded oil volume directly affects suspension damping accuracy. Fitting the FSK-015 restores the hydraulic integrity of the fork, ensuring the damping characteristics your ZX-10 R was set up to deliver are fully preserved. Whether the bike is running factory suspension settings or a custom K-Tech service tune, the quality of the seal directly underpins the consistency of every setting dialled in.

Fitment & Compatibility

This kit is designed specifically for the following models:

  • Kawasaki ZX-10 R — 2011 to 2026
  • Kawasaki ZX-10 RR — 2011 to 2026

Fork tube outer diameter: 43.00 mm inner seal diameter. If you are unsure whether this kit matches your specific model year variant, please contact the Inter-Pace technical team before ordering.

Installation Note

Correct installation requires dedicated fork seal driver tools and a working knowledge of inverted or conventional fork disassembly procedures. K-Tech recommend that the FSK-015 is fitted by an authorised K-Tech Service Centre to ensure maximum performance and safety. Improper installation can result in premature seal failure or fork oil contamination of the braking system.
