DescriptionThe whole story▼
Prevent fork oil loss before it compromises your front suspension. The K-Tech FSK-024 fork oil seal and dust cap kit pairs precision-engineered NOK seals with dedicated dust caps to restore full sealing integrity to the BMW S1000RR K46 (2009–2018) — keeping contamination out and fork oil exactly where it belongs.
Key Features
- NOK-sourced oil seals — a brand trusted by leading Japanese suspension manufacturers as original equipment, chosen for their dimensional accuracy and long service life.
- Complete paired set: two oil seals and two dust caps cover both fork legs in a single purchase.
- Inner diameter of 46.00 mm and outer diameter of 58.00 mm are matched precisely to S1000RR K46 fork tube specifications — no trimming, no compromise on fit.
- Dust caps form the first line of defence against road grit, water, and debris that accelerate seal wear and degrade fork action.
- Direct OEM-specification replacement minimises installation time and eliminates guesswork during a fork service.
Quality & Engineering
NOK is one of the world's foremost manufacturers of sealing components for suspension systems. Their oil seals are found on the production lines of many Japanese fork manufacturers because the dimensional tolerances, lip geometry, and compound specification consistently meet or exceed OEM standards. Choosing NOK-derived seals for your S1000RR means you are fitting a component built to the same reliability benchmark as the unit that left the factory — not a generic aftermarket substitute.
K-Tech has packaged these seals under part number FSK-024 specifically for the K46 chassis, so you can be confident the sealing geometry is correct for the fork tube and outer tube dimensions used across the 2009–2018 model run.
Road & Track Use
Whether the bike sees daily road riding or regular track days, a weeping fork seal is not merely an inconvenience — oil on a brake disc or tyre represents a genuine safety risk. Replacing seals at the first sign of film or weeping restores the hydraulic damping characteristics K-Tech suspension is calibrated around, keeping rebound and compression response consistent lap after lap or mile after mile.
Installation Note
K-Tech recommends installation by an authorised K-Tech Service Centre. Correct fitting requires specialist tools and technical knowledge to ensure maximum performance and safety. Attempting installation without the appropriate seal driver and fork-specific tooling risks damaging the new seals or scoring the fork tubes.
