Manufactured by NOK — the Japanese seal specialist trusted by the world's leading suspension builders — this pair of fork oil seals is engineered to maintain consistent damping performance lap after lap, eliminating the pressure loss and fork-leg contamination that degrade high-speed handling.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eNOK-manufactured fork oil seals: the benchmark choice of top-tier Japanese suspension OEMs for proven longevity under race conditions\u003c\/li\u003e\n\u003cli\u003eExact-fit geometry (43.00 x 55.10 x 11.00\/14.00 mm) engineered specifically for the Panigale V4 R fork internals — no adaptation required\u003c\/li\u003e\n\u003cli\u003eSupplied as a matched pair so both fork legs are serviced simultaneously, preserving balanced damping response\u003c\/li\u003e\n\u003cli\u003ePrevents fork oil weeping and contamination of the brake caliper and tyre — critical at track speeds where any fluid ingress becomes a safety hazard\u003c\/li\u003e\n\u003cli\u003eDrop-in OEM-specification replacement, making scheduled fork service straightforward at an authorised K-Tech centre\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance at the Track\u003c\/h2\u003e\u003cp\u003eThe Ducati Panigale V4 R is a homologation-special built around Superbike World Championship demands, and its fork seals must match that brief. K-Tech selected NOK compounds that resist the thermal cycling of back-to-back track sessions and the constant micro-movement generated by aggressive braking and corner-entry loads. Worn or weeping fork seals introduce unpredictable fork action precisely when the rider needs feedback they can trust; replacing them with the FSS-021 kit restores the fork to its designed operating envelope.\u003c\/p\u003e\u003ch3\u003ePrecision Dimensions\u003c\/h3\u003e\u003cp\u003eThe seals measure 43.00 mm inner diameter, 55.10 mm outer diameter, with dual heights of 11.00 mm and 14.00 mm — tolerances that ensure a positive lip contact with the fork stanchion without excessive drag, preserving the low-friction feel the Panigale V4 R chassis is tuned around.\u003c\/p\u003e\u003ch2\u003eInstallation Note\u003c\/h2\u003e\u003cp\u003eThese seals are compatible exclusively with the R variant of the Ducati Panigale V4; they are not a direct fit for standard V4 or V4 S models.
