Engineered specifically for the Ducati Panigale V4 S, this K-Tech fork oil seal and dust cover kit delivers the kind of precise, long-lasting protection that keeps your front suspension performing exactly as intended — on road and on track, lap after lap, season after season. Manufactured by NOK, a globally recognised OEM seal supplier to the world's leading Japanese suspension manufacturers, every component in this kit meets the exacting standards your V4 S demands.
Key Features
- NOK-manufactured oil seals and dust covers — the same supplier trusted by major OEM suspension brands worldwide
- Provides reliable, leak-free sealing at the front fork to maintain consistent damping performance
- Dust covers shield the inner fork tubes from dirt, grit and moisture, extending service intervals
- Designed as a direct OEM replacement for the Ducati Panigale V4 S front forks — fits without modification
- Equally suited to road use and track days, where fork integrity directly influences lap times and rider confidence
- Part number FSK-021 ensures straightforward, error-free ordering
Quality & Construction
NOK is one of the most respected names in sealing technology, supplying precision oil seals and dust caps to Japanese suspension manufacturers as original equipment. The compounds used offer excellent resistance to fork oil degradation, temperature cycling and the abrasive contamination that comes with hard track use. The result is a seal that maintains consistent stiction characteristics and prevents the oil weeping that can lead to unpredictable fork behaviour — precisely the kind of problem that is unacceptable on a machine as capable as the Panigale V4 S.
Road & Track Performance
A leaking or contaminated fork seal does not just create a cosmetic problem; it directly compromises damping consistency and, ultimately, rider safety. Replacing worn seals with this K-Tech kit restores the fork to factory specification, ensuring the Öhlins NIX30 forks fitted to the V4 S respond correctly across the full range of compression and rebound settings. Whether you are chasing consistency through technical corners at a circuit or simply want confidence on your favourite road, fresh seals are a foundational part of suspension maintenance.
Fitment & Compatibility
This kit is designed exclusively for the S-variant of the Ducati Panigale V4. It is not suitable for the standard V4, V4 R or V4 SP unless those models share an identical fork specification — always verify before fitting.

Installation Note
Fork seal replacement requires specialist tools and technical knowledge. K-Tech recommends that this kit be fitted by an authorised K-Tech service centre to ensure correct installation and to maintain optimal suspension performance and rider safety.
