DescriptionThe whole story▼
K-Tech's FSS-015 oil seal kit brings SHOWA-NOK engineering precision to your Honda CBR 1000 RR fork service. Produced by NOK — one of the most respected names in fork seal manufacture and a trusted original-equipment supplier to leading Japanese suspension manufacturers — these seals combine a heritage of proven engineering with the exacting dimensional accuracy your CBR demands.
Key Features
- Manufactured by NOK, the OE seal supplier of choice for major Japanese suspension manufacturers, ensuring a quality standard that rivals the original fitment
- Dimensions of 43.00 x 54.00 x 11.00 mm guarantee a direct, no-modification replacement for the Honda CBR 1000 RR Showa fork
- Prevents fork oil weeping and loss, maintaining consistent damping performance across street riding and track sessions alike
- Complete kit containing two oil seals covers both fork legs in a single service operation
- Drop-in fitment eliminates guesswork and reduces workshop time during routine fork maintenance
Engineering Heritage and Finish
NOK's reputation has been built over decades of supplying precision sealing solutions to the motorsport and automotive industries. Their fork oil seals are engineered to exacting tolerances, with lip profiles and rubber compounds developed specifically to resist the thermal cycling, hydraulic pressure, and side-loading that a performance motorcycle fork experiences under hard braking and high-speed direction changes. The FSS-015 kit draws directly on that heritage, carrying the same material and dimensional specification trusted by factory suspension builders.
Performance on Road and Track
A weeping fork seal does more than leave an oily stain — it degrades damping consistency, contaminates the brake disc and pads, and compromises rider confidence. Replacing the seals with a correctly specified NOK unit restores the fork to its designed operating envelope, whether you are commuting on damp British roads or chasing lap times on track days. With two seals included in the FSS-015 kit, a complete fork service is straightforward and thorough.
Fitment and Compatibility
This kit is designed exclusively for the Honda CBR 1000 RR covering model years 2004 through to 2019. It is not intended for use on any other model or year range outside this specification.
Installation Note
Fitting fork oil seals requires specialist tools and technical knowledge to ensure correct installation and full safety. K-Tech recommends that installation is carried out exclusively by an authorised K-Tech Service Centre.
