Keeping your Yamaha YZF-R6's forks in daily working order starts with reliable seals, and the K-Tech FSK-006 kit delivers exactly that. Sourced from NOK — one of the most trusted seal manufacturers in the industry — this two-piece oil seal and dust cap set is engineered precisely for the RJ11 and RJ15 chassis, giving you a direct, fuss-free replacement that protects fork oil integrity and keeps road grime where it belongs: outside the fork leg.
Key Features
- NOK-manufactured seals for exceptional durability and consistent oil retention across everyday road use
- Matched set of two oil seals and two dust caps — everything needed to service both fork legs in a single purchase
- Exact 41 mm inner diameter spec ensures a precise fit for Yamaha YZF-R6 RJ11 and RJ15 fork tubes with no modification required
- Dust caps provide a reliable barrier against water, road dirt and fine particles that accelerate inner-tube wear
- Part number FSK-006 makes reordering and workshop identification straightforward
Build Quality & Everyday Value
Worn fork seals are one of the most common — and most overlooked — causes of degraded suspension feel. Oil weeping down the fork leg not only contaminates the brake disc but steadily robs the damping of its character. The K-Tech FSK-006 kit addresses this at the source: NOK rubber compounds are formulated to resist the thermal cycling that street riding demands, maintaining a consistent seal whether you are filtering through city traffic or pushing hard on your favourite B-road.
Because the kit covers both fork legs, you replace both sides simultaneously — the correct approach for balanced suspension performance and the most economical use of your workshop time. At 41 mm inner diameter and 53 mm outer diameter, the dimensions are a direct match for the factory fork tubes; no adapters, no compromises.
Installation Note
Installation requires specialist tools and knowledge of fork internals. K-Tech recommends fitting by an authorised K-Tech Service Centre to ensure correct seating and safe operation.
