DescriptionThe whole story▼
Keeping your front fork in peak condition is one of the most cost-effective maintenance steps you can make, and the K-Tech FSK-026 fork seal and dust cap kit gives the BMW S1000RR K67 (2019–2026) exactly the protection it deserves. Manufactured by NOK — the supplier of choice for leading Japanese suspension manufacturers as original equipment — these seals deliver the kind of fit and longevity that keep your chassis performing consistently mile after mile.
Key Features
- NOK-manufactured oil seals: the same quality standard found in OE suspension from top Japanese manufacturers, offering exceptional durability and sealing reliability.
- Complete kit includes two oil seals and two dust caps, covering both fork legs in a single purchase — no hunting for individual components.
- Precise 45 mm inner diameter and 58 mm outer diameter geometry ensures a correct, leak-free fit against the S1000RR K67 fork tubes.
- Dust caps provide a physical barrier against grit, road debris and moisture, protecting the fork stanchions and extending the service life of the oil seals themselves.
- Prevents fork oil weeping that can contaminate the front brake and compromise handling — a straightforward service item with genuine safety implications.
Why Regular Fork Seal Replacement Matters
Worn fork seals are one of the most common causes of degraded front-end feel on high-performance machines. Oil seeping past a damaged seal not only reduces damping precision — it can coat the brake disc and pad with oil, creating a serious hazard. Replacing the seals and dust caps as a paired set at the recommended service interval restores the fork's original damping characteristics and gives you confidence in the front end whether you are commuting, touring or pushing on at track days.
K-Tech has built its reputation on precision suspension components and servicing products used by World Superbike and British Superbike teams. The FSK-026 brings that same engineering standard to a straightforward maintenance kit that every S1000RR owner will need sooner or later.
Fitment & Compatibility
This kit is designed specifically for the BMW S1000RR K67, covering all variants produced from 2019 to 2026. Always confirm your frame designation before ordering to ensure correct fitment.
Installation Note
Installation requires specialist tools and technical knowledge. K-Tech recommends that this kit is fitted by an authorised K-Tech Service Centre to ensure correct seating of the seals, maximum performance and safety.
