Every long ride or hard track session puts your fork internals at the mercy of road grit, brake dust and trail debris. The K-Tech DSS-017 Dust Seals Kit for the Yamaha YZF-R1 (2003-2026) delivers all-day, all-season confidence by keeping contamination out of your fork legs — so the suspension action that felt precise on lap one still feels precise on lap thirty.
Key Features
- Manufactured by NOK, the supplier of choice for all leading Japanese suspension manufacturers — the same quality standard found in original-equipment forks worldwide.
- Direct OEM replacement fit: dimensions are matched precisely to the YZF-R1 fork specification, so installation requires no modification, trimming or adapting.
- 43.00 mm inner diameter and 55.50 mm outer diameter keep the dust seal seated firmly against the fork tube under repeated compression cycles.
- Dual-height profile (4.70 mm / 14.00 mm) provides the correct lip engagement to wipe the fork stanchion clean on every stroke.
- Kit includes two dust seals — one per fork leg — covering a complete service in a single purchase.
- Sealing out dust and airborne particles reduces wear on the main oil seals beneath, directly extending fork service intervals and protecting your investment.
Performance on Road and Track
Fork dust seals are a consumable that riders often overlook until the main oil seals start weeping. Replacing them with NOK-manufactured units at each service interval is the most cost-effective way to maintain the precise, consistent fork action the YZF-R1 is renowned for. Whether you are commuting daily or threading through a technical track chicane, clean fork internals translate into predictable handling and feedback you can trust.
Installation Notes
K-Tech recommends that the DSS-017 kit is fitted by an authorised K-Tech service centre to ensure correct seating and to maintain suspension performance and safety standards. As with any fork seal service, clean the stanchions thoroughly before fitting to avoid trapping any debris behind the new seals.
Fitment & Compatibility
The K-Tech DSS-017 is designed exclusively for the Yamaha YZF-R1, covering the full production run from 2003 through to 2026. This spans every major generation of the R1, including the carburettor-era models, the crossplane-crank generation and the current electronics-laden MotoGP-derived variants.
