DescriptionThe whole story▼
When your BMW S1000RR K46 is being pushed hard on track, fork seal integrity is non-negotiable. The K-Tech FSS-024 oil seals kit pairs NOK-manufactured seals with SACHS engineering expertise to deliver a direct OEM replacement that matches — and in service life often exceeds — the factory specification. Whether you're rebuilding after a season of circuit work or carrying out preventive maintenance before the next race weekend, this kit restores full fork performance and keeps oil where it belongs.
Key Features
- NOK-manufactured seals developed in collaboration with SACHS — the same supply chain that underpins OEM fork assembly quality
- Direct drop-in replacement for the original seals on the BMW S1000RR K46, no modification required
- Precision dimensions (46.00 mm inner diameter, 58.00 mm outer diameter) ensure a leak-free fit within the fork leg
- Dual-height profile — 8.50 mm and 11.50 mm — replicates the original seal geometry for correct oil retention and dust exclusion
- Kit includes two oil seals, covering both fork legs in a single purchase
- Protects against oil loss and contamination that degrades damping consistency under repeated braking and cornering loads
Performance on Track and Road
A weeping fork seal is more than a cosmetic issue — oil migrating onto the brake disc or tyre is a safety hazard at any speed, and it is especially dangerous during the aggressive braking zones and high-speed direction changes that characterise circuit riding. The K-Tech FSS-024 kit uses high-grade NOK compounds selected for their resistance to the thermal cycling that race use imposes on fork internals. The result is consistent damping response lap after lap, with no progressive degradation caused by escaping fork oil.
On the road, the same properties translate into predictable front-end feedback and reduced maintenance intervals. Riders who commute or tour on their S1000RR benefit from the peace of mind that comes with a seal specification originally chosen for racing-derived machinery.
Fitment & Compatibility
This kit is designed exclusively for the BMW S1000RR K46 manufactured between 2009 and 2018. Verify your model year before fitting. Installation requires specialist tools and fork-service knowledge; K-Tech recommend fitting be carried out by an authorised K-Tech Service Centre.
