Reliable fork sealing is a matter of safety as much as performance. The K-Tech Fork Oil Seal Kit FSS-021 is engineered specifically for the Ducati Panigale V4 S (2018–2024), supplying a pair of precision-manufactured NOK oil seals in the exact dimensions the S-model's forks demand — so every service restores the suspension to its original, leak-free standard.
Key Features
- Manufactured by NOK, the global benchmark in fork oil seals and the preferred supplier of Japan's leading suspension manufacturers — chosen for exceptional dimensional accuracy and long service life.
- Exact-fit dimensions (43.00 x 55.10 x 11.00/14.00 mm) matched to the Ducati Panigale V4 S fork specification, eliminating the risk of incorrect seating or premature failure.
- Dual-height profile (11.00 mm and 14.00 mm) provides positive oil retention and effective dust exclusion, keeping the fork legs clean and the damping consistent.
- Supplied as a complete pair — both legs serviced in a single purchase, ensuring balanced fork performance and simplifying workshop planning.
- Part number FSS-021 is unique to the S-model fitment; never risk fitting a seal dimensioned for a different variant.
Performance & Build Quality
NOK seals are produced to tolerances that match OEM standards, using elastomer compounds formulated to resist the heat cycling, fork oil chemistry, and high-load deflections typical of a high-performance superbike like the Panigale V4 S. The result is a seal that maintains its lip geometry over an extended service interval, preventing the oil weeping that leads to contaminated brake discs, degraded damping and accelerated fork bush wear. K-Tech has specified this seal kit as part of its professional suspension service range — the same components used by authorised K-Tech service centres worldwide.
Installation Note
These seals require specialist fork-seal installation tools and technical knowledge of inverted fork assembly. Fitting should be carried out by an authorised K-Tech Service Centre or a qualified suspension technician. Correct installation is essential to ensure full sealing performance and rider safety.
Fitment & Compatibility
This kit is exclusively designed for the S models of the Ducati Panigale V4 range. It is not suitable for the standard Panigale V4 or other variants. Always verify your model designation before ordering.
