Fork seals are the first line of defence against oil contamination and loss of damping precision — and on the Kawasaki ZX-6R, 636, and ZX-6RR (2005–2026), degraded seals compromise both safety and handling. The K-Tech FSS-007 oil seal kit uses NOK-manufactured seals, a brand trusted by OEM and aftermarket suspension specialists worldwide for exceptional sealing integrity and service life. Fitted in pairs, these seals restore factory-correct fork performance and prevent the oil weep that leads to faded damping and contaminated brake components.
Key Features
- NOK-sourced seals — a globally respected manufacturer relied upon by suspension engineers for consistent, long-service sealing performance.
- Direct OEM replacement geometry: 41.00 mm inner diameter, 54.00 mm outer diameter, 11.00 mm height — no modification or shimming required.
- Supplied as a complete pair so both legs are refreshed in a single service, ensuring balanced fork behaviour.
- Prevents oil weepage that degrades damping response, contaminates the brake disc, and compromises rider safety.
- Specifically validated for Kawasaki ZX-6R / 636 / ZX-6RR models fitted with Ohlins / SOQI forks.
Precision Sealing for a High-Performance Supersport Fork
The ZX-6R's fork demands tight dimensional tolerances to maintain consistent compression and rebound damping across a full riding season. The FSS-007 kit matches those tolerances exactly. NOK's seal compound resists the thermal cycling generated during track use while remaining supple enough at low temperatures to maintain a positive lip seal on cold morning roads. This dual-environment capability is what separates quality replacement seals from generic alternatives that crack or harden prematurely.
Installation Note
This kit is intended for Kawasaki ZX-6R / 636 / ZX-6RR (2005–2026) models equipped with Ohlins / SOQI forks. Installation requires specialist tools and suspension knowledge. Fitting must be carried out exclusively by an authorised K-Tech Service Centre to guarantee full performance and safety. Attempting installation without the correct equipment may damage the seals or fork internals.
