Manufactured by NOK — the original-equipment seal supplier chosen by Japan's leading suspension manufacturers — these precision oil seals are engineered to hold under the punishing loads of both track days and hard road riding, cycle after cycle.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eNOK-manufactured seals: the same supplier trusted as OEM by Japan's foremost suspension brands, delivering proven reliability and exceptional service life.\u003c\/li\u003e\n\u003cli\u003eExact-fit dimensions of 43.00 x 55.10 x 11.00\/14.00 mm ensure a direct, no-modification replacement on RN32, RN49 and RN65 chassis.\u003c\/li\u003e\n\u003cli\u003eComplete kit with two oil seals covers a full fork service in one purchase, eliminating the risk of mismatched components.\u003c\/li\u003e\n\u003cli\u003eMaintains consistent damping performance under extreme conditions — track heat, repeated braking zones and aggressive corner loading.\u003c\/li\u003e\n\u003cli\u003ePrecision sealing lip geometry prevents oil weeping and contamination ingress, protecting the fork internals between service intervals.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance on Track and Road\u003c\/h2\u003e\u003cp\u003eThe Yamaha YZF-R1 M was built around an Öhlins Electronic Racing Suspension system, and any compromise in fork seal integrity directly undermines that investment. A weeping seal bleeds off oil film, corrupts damping consistency and deposits oil onto the brake disc — an unacceptable scenario on circuit. The FSS-021 kit restores the fork to its designed operating state with components that meet the same specification standard as factory-fitted seals, not a lesser aftermarket approximation.\u003c\/p\u003e\u003cp\u003eNOK's manufacturing tolerances are held to the exacting standards demanded by OEM suspension contracts. That same precision translates directly to aftermarket fitment: the seals seat correctly at first installation and resist the thermal cycling that degrades cheaper alternatives over repeated track sessions.\u003c\/p\u003e\u003ch2\u003eInstallation Note\u003c\/h2\u003e\u003cp\u003eThis kit is suitable for M models of the Yamaha YZF-R1 only — it is not interchangeable with the standard R1.
