DescriptionThe whole story

Keeping your forks in honest working order doesn't need to be complicated. The K-Tech FSK-007 fork oil seal and dust cap kit gives your Triumph Street Triple 765 a reliable, cost-effective service solution, pairing NOK-manufactured oil seals — industry-standard components trusted by suspension specialists worldwide — with matching dust caps that lock out road grime before it ever reaches the fork legs.

Key Features

  • Exact-fit replacement for Triumph Street Triple 765 S, R and RS models from 2017 to 2026 — no guesswork, no modification required.
  • Oil seals manufactured by NOK, one of the most respected names in fork seal production, ensuring consistent sealing performance over a long service life.
  • 41 mm inner diameter / 54 mm outer diameter seals matched to the factory fork tube specification.
  • Dust caps included to prevent dirt, moisture and abrasive particles from degrading the new seals prematurely.
  • A genuine value-for-money service kit: replace both seals and both dust caps in a single purchase, keeping your fork internals protected between services.

Quality You Can Rely On

NOK's fork seals are a staple of professional suspension workshops for good reason. Their rubber compound maintains elasticity across a wide temperature range and resists the oil degradation that causes lesser seals to harden and weep. Pairing them with fresh dust caps — often overlooked during a basic fork service — completes the protection and extends the interval before your next seal change.

Everyday Usability

Whether you commute on your Street Triple 765 during the week or push it hard at the weekend, fork seals that do their job quietly are the foundation of safe, consistent handling. A weeping fork leg not only coats the leg and lower leg in oil but can contaminate the front brake disc, creating a genuine safety hazard. Replacing seals at the first sign of seepage — or as a preventative measure during a scheduled service — is the sensible, economical choice. The FSK-007 kit keeps that job straightforward and affordable.

Installation Note

Installation should be carried out exclusively by an authorised K-Tech Service Centre. Specialist tools and techniques are required for a safe and correct fitment.
