DescriptionThe whole story▼

Engineered to keep your Panigale V4's forks performing as they should, lap after lap and mile after mile, the K-Tech FSS-015 Oil Seals Kit delivers a direct OEM-quality replacement for worn fork seals. Manufactured by NOK — the supplier of choice for leading Japanese suspension manufacturers — these seals are designed to slot straight in without modification, restoring consistent damping feel and keeping oil where it belongs.

Key Features

  • NOK-manufactured seals: trusted by top Japanese suspension OEMs for their proven durability and sealing integrity
  • Direct OEM replacement with dimensions of 43.00 x 54.00 x 11.00 mm — no adaptation required
  • Complete kit supplies both fork legs in a single purchase, covering the full service in one go
  • Prevents fork oil weepage that degrades damping response and contaminates brake components
  • Precise fitment tailored to the Ducati Panigale V4 (2018–2024) fork tube diameter and seal housing

All-Day Comfort Starts with the Fork Seals

A leaking or degraded fork seal does far more than leave an oily smear on your stanchion. It allows dirt and moisture to migrate into the fork internals, accelerating wear on bushings and the oil itself. Over a long ride or a full track day, the progressive loss of damping consistency translates directly into rider fatigue — that unsettled front end you feel mid-corner is your body working overtime to compensate. Fitting a fresh set of NOK seals via the K-Tech FSS-015 kit restores the precise, predictable fork action the Panigale V4 was designed to deliver, so you arrive at the end of a session feeling composed rather than worn out.

Build Quality

NOK is one of the most respected seal manufacturers in the industry, and their products are not simply adequate replacements — they are the standard against which other seals are measured. The compound used in these seals maintains its flexibility and sealing lip geometry across a wide operating temperature range, resisting the hardening and cracking that causes cheaper alternatives to fail prematurely. K-Tech has specified these seals specifically for the Ducati Panigale V4 to ensure the interference fit and lip profile match the OEM specification exactly.

Fitment and Compatibility

This kit is designed exclusively for the following motorcycle:

  • Ducati Panigale V4 — all variants, model years 2018 to 2024

Installation requires specialist fork tooling and technical knowledge. K-Tech recommends that fitting is carried out by an authorised K-Tech Service Centre to ensure full performance and safety of the product.
