DescriptionThe whole story

K-Tech's FSK-007 fork seal kit brings genuine engineering heritage to the Kawasaki ZX-6R, ZX-636 and ZX-RR — sourced from NOK, the world's foremost manufacturer of fork seals, and finished to the exacting tolerances that K-Tech suspension products are renowned for. Every kit is precision-matched to the 41 mm fork legs fitted across two decades of these iconic Kawasaki supersports, ensuring a leak-free, contamination-resistant result that maintains consistent damping feel whether you're commuting or pushing hard on circuit.

Key Features

  • NOK-manufactured oil seals: NOK are the benchmark supplier for fork seals globally, delivering the material quality and dimensional accuracy that OEM and aftermarket specialists trust above all others.
  • Matched dust caps included: the dust caps work in tandem with the oil seals to block dirt, grit and moisture from ever reaching the fork internals, protecting stanchion surfaces and extending service intervals.
  • Precision 41 mm inner diameter: machined to a 41.00 mm inner diameter and 54.00 mm outer diameter, these seals drop into the ZX-6R fork legs without modification or shimming.
  • Long fitment window — 2005 to 2026: covers every iteration of the ZX-6R, ZX-636 and ZX-RR from the 2005 model year right through to 2026, making this a go-to kit for workshops carrying a single SKU across the range.
  • Complete set, ready to fit: two oil seals and two dust caps supplied together, so both fork legs can be rebuilt in one session with matching components.

Build Quality & Heritage

The K-Tech name carries real weight in suspension circles — the brand supplies and supports professional race teams at World Superbike and British Superbike level, and that experience flows directly into the quality standards applied to service parts like this seal kit. Choosing NOK as the seal manufacturer is a deliberate decision: NOK hold OEM supply contracts with major motorcycle manufacturers worldwide, and their compounds are engineered to resist the thermal cycling, hydraulic pressure and lateral loading that a high-performance fork experiences across its service life. The result is a kit that looks understated in the box but performs with the consistency that serious riders demand.

Installation Guidance

Correct fork seal installation requires specialised tools and a thorough understanding of fork service procedures. K-Tech specify that this kit should be installed exclusively by an authorised K-Tech Service Centre to ensure optimal performance and safety. Attempting installation without the correct seal driver and technical knowledge risks damage to the stanchion, premature seal failure or compromised handling.
