DescriptionThe whole story▼
Precision-made from NOK rubber compound, the K-Tech DSS-017 dust seals kit delivers the kind of fork protection that the Aprilia RSV4 platform genuinely deserves. NOK is the Japanese sealing specialist trusted by OEM manufacturers worldwide, and these direct-fit dust seals bring that same exacting standard to your front fork as a replacement or service item — whether you ride road or track.
Key Features
- NOK-manufactured rubber compound: a globally respected Japanese seal maker whose materials outlast generic alternatives in both heat cycling and abrasion resistance.
- Direct OEM-specification replacement: dimensionally identical to the factory fit, so installation is straightforward with no modification required.
- Full environmental barrier: seals out road grime, dust, and moisture before they can migrate past the fork oil seals and cause premature wear.
- Extended fork service life: keeping contamination away from the inner stanchions and oil seals reduces friction, maintains damping consistency, and delays costly strip-downs.
- Supplied as a pair: both fork legs covered in one kit, part number DSS-017.
Build Quality and Materials
The DSS-017 kit is where material choice makes a meaningful difference. NOK's rubber formulation is engineered to remain flexible across a wide temperature range — from cold early-morning starts to sustained track sessions where fork heat builds quickly. The lip geometry holds a precise, consistent contact pressure against the stanchion surface, wiping contamination cleanly without imposing additional friction that would dull the fork's response. At 43.00 mm inner diameter with a 55.50 mm outer diameter, these seals are machined to exact tolerances that ensure positive seating in the fork slider housing.
Fork Maintenance and Performance
Fork dust seals are a maintenance item that is easy to overlook until the damage is already done. Grit that passes a worn dust seal acts as a lapping compound against the hard-chrome or DLC-coated stanchion, scoring the surface and accelerating oil seal failure. Fitting fresh NOK seals at each oil-seal service interval is the simplest insurance policy for an otherwise expensive front-end rebuild. For RSV4 owners who track their machines, the return on this investment is felt immediately in consistent, repeatable damping that does not degrade lap to lap.
