Changing fork seals and springs Ducati 900SS

In this video, I rebuild the Showa front forks on my Ducati 900SS/SP, replacing the worn fork seals with high-quality THK seals. After nearly 30 years, the original seals often start leaking, leading to reduced damping, oil on the fork legs, and compromised handling.

The 900SS/SP came from the factory with Showa fully adjustable inverted forks , a highlight of Ducati’s 1990s Supersport lineup. Keeping them in perfect condition ensures the classic trellis chassis performs as intended.

By upgrading to durable THK seals, you get improved longevity, better oil retention, and consistent suspension performance — ideal whether you’re restoring your Supersport or carving up back roads.

🏍️ Why replace fork seals?
✔️ Stop fork oil leaks
✔️ Restore smooth suspension travel
✔️ Maintain braking and cornering performance
✔️ Extend the life of your Showa forks

If you’re passionate about keeping your Ducati 900SS/SP both reliable and authentic, fresh fork seals are an essential maintenance step. Ride safe and keep the legend alive!
