DescriptionThe whole story▼
Keeping your Honda CBR 1000 RR-R SP's forks in perfect working order starts with the right oil seals — and the K-Tech FSS-021 kit delivers exactly that. Manufactured by NOK, the seal supplier trusted by leading Japanese suspension builders, these fork oil seals combine everyday reliability with long-term durability, making this kit the sensible first choice for routine fork maintenance on the SC82 platform.
Key Features
- NOK-manufactured seals — the preferred supplier of major Japanese suspension manufacturers, chosen for proven reliability and service life
- Precision fitment dimensions of 43.00 x 55.10 x 11.00/14.00 mm ensure a leak-free, factory-quality seal every time
- Kit contains two oil seals — a complete pair to service both fork legs in a single job
- Designed specifically for the SP variants of the Honda CBR 1000 RR-R SC82; not a universal part adapted to fit
- Consistent sealing performance prevents oil weepage and maintains correct fork oil level for predictable suspension behaviour
Build Quality and Performance
The FSS-021 kit is built around NOK seals — a name that appears on OEM suspension units from several of the most respected Japanese manufacturers. The dual-height profile (11.00 mm inner lip / 14.00 mm outer) is matched to the SC82's 43 mm fork tube diameter, ensuring the seal seats correctly in the fork leg and remains effective across a full range of temperatures and riding conditions.
Whether you are refreshing the forks as part of a scheduled service interval or addressing a weeping seal before a track day, this kit gives you confidence that the replacement part meets the same standard as the original. Correct fork oil level is fundamental to suspension geometry and feel, so using a properly dimensioned seal is not a cosmetic concern — it is a handling and safety issue.
Fitment and Compatibility
This kit is designed exclusively for the SP models of the Honda CBR 1000 RR-R SC82 produced between 2020 and 2026. It is not suitable for the standard (non-SP) CBR 1000 RR-R or for earlier SC59/SC77 variants, as fork tube diameters and seal dimensions differ. Always confirm your model designation before ordering.
Installation Note
Fork seal replacement requires specialist tools and knowledge of suspension systems. K-Tech recommend that installation is carried out by an authorised K-Tech Service Centre to ensure correct seating, full performance and rider safety.
