DescriptionThe whole story▼

Every mile you put into your Triumph Street Triple 765 depends on forks that move freely and consistently. The K-Tech Dust Seals Kit DSS-007 fits perfectly from the first installation and stays that way, keeping dirt, grit and road contaminants out of your fork legs so the suspension behaves exactly as it should, whether you are threading through city traffic or pressing on through a long mountain pass.

Key Features

  • Precision fit engineered as a direct OEM replacement for the Triumph Street Triple 765 S, R and RS — no modification required.
  • Manufactured from high-grade NOK rubber compound for long-lasting resilience against moisture, dust and road debris.
  • Exact dimensions (41.00 mm inner diameter, 54.40 mm outer diameter) ensure a consistent seal across the full range of fork travel.
  • Supplied as a pair — everything needed for a complete fork service in one kit.
  • Prevents contaminant ingress that would otherwise accelerate fork oil seal wear and degrade suspension performance over time.

All-Day Riding Confidence

A worn or ill-fitting dust seal might seem like a minor detail, but over the course of a long riding season its effects compound. Dust and fine grit work past degraded seals and into the fork internals, causing premature wear on oil seals, scoring stanchions and altering damping characteristics in ways that are difficult to diagnose. Replacing the dust seals with K-Tech's NOK-produced units restores the original barrier and lets the fork function as Triumph intended — with a smooth, consistent action that you can feel in every corner.

Build Quality

K-Tech specify NOK material for these seals because NOK is widely regarded as the industry benchmark for fork seal manufacture. The compound maintains its flexibility across a broad temperature range and resists the oils, cleaning agents and road chemicals a motorcycle encounters in normal use. The two-height lip profile (4.60 mm and 14.00 mm) provides layered protection: the shorter lip wipes the stanchion on compression while the taller lip guards against heavier debris on rebound.

Fitment and Compatibility

This kit is designed exclusively for the following models:

  • Triumph Street Triple 765 S (2017–2026)
  • Triumph Street Triple 765 R (2017–2026)
  • Triumph Street Triple 765 RS (2017–2026)

Installation should be carried out by an authorised K-Tech service centre using the appropriate seal-driving tools and techniques. Correct installation is essential to guarantee seal integrity and long-term fork performance.
