NOK Corporation holds a global reputation for rubber-to-metal sealing technology used in both OEM production lines and top-level motorsport. The seals in this kit are manufactured to tight dimensional tolerances, using a rubber compound chosen for resistance to fork oil degradation, temperature cycling, and the ingress of road grime. The result is a seal that not only fits correctly on first installation but maintains its integrity across extended service intervals — critical for a machine that may see both daily road use and weekend track days.\u003c\/p\u003e\u003ch2\u003ePerformance and Road Use\u003c\/h2\u003e\u003cp\u003eWorn or weeping fork seals are among the most common causes of degraded front-end feel. Once oil escapes past the seal and migrates onto the fork stanchion, it contaminates the dust wiper and, more critically, the brake disc and pads — a genuine safety concern. Replacing both seals with genuine NOK units as supplied in the FSS-007 kit restores the hydraulic integrity of the fork, bringing back the precise, communicative steering the Ninja 400 was designed to deliver. Whether you use the bike for urban commuting or spirited A-road riding, correct fork function is non-negotiable.\u003c\/p\u003e\u003ch2\u003eInstallation Note\u003c\/h2\u003e\u003cp\u003eThis kit is designed exclusively for Kawasaki Ninja 400 models from 2018 to 2023 equipped with Ohlins\/SOQI forks.
