K-Tech Fork Oil Seal Kit Honda CBR 1000 RR-R SC82 (2020–2026) FSS-015

Precision matters when you are chasing the limits of a 217 hp Fireblade. The K-Tech FSS-015 fork oil seal kit brings genuine NOK-manufactured seals to the Honda CBR 1000 RR-R SC82, honouring a lineage of SHOWA suspension engineering that has dominated race paddocks worldwide. These are not aftermarket approximations — they are the exact-specification seals chosen by leading Japanese suspension manufacturers for their unmatched consistency and service life.

Key Features

• Genuine NOK seals: manufactured to the exacting tolerances demanded by SHOWA suspension systems, delivering the same heritage quality found in factory race programmes.
• Direct OEM replacement: dimensioned precisely at 43.00 x 54.00 x 11.00 mm for a drop-in fit on the SC82 fork legs — no modification, no guesswork.
• Complete two-seal kit: both fork legs serviced in a single purchase, ensuring matched performance across the front axle.
• Positive oil retention: maintains correct fork oil level under sustained track stress, preserving consistent damping response lap after lap.
• Confirmed SC82 fitment: validated specifically for the 2020–2026 Honda CBR 1000 RR-R — not a generic cross-reference.

Design, Finish and Heritage

K-Tech Suspension has built its reputation supplying suspension components to World Superbike and British Superbike teams, and that pedigree informs even their service parts. The FSS-015 seal kit carries the NOK name — a manufacturer synonymous with precision rubber engineering since 1939 and the preferred choice of SHOWA for their GP and production-class forks alike. The seals themselves feature a multi-lip profile refined through decades of high-load, high-temperature application, resisting the thermal cycling that degrades cheaper alternatives over a hard season's riding. When you fit K-Tech seals to your Fireblade, you are connecting a road or track machine to a direct line of competition-proven suspension technology.

Performance on Road and Track

A weeping fork seal is more than a cosmetic concern: oil migration onto the brake disc is a serious safety issue, and even minor fluid loss shifts the fork's oil-to-air ratio, softening the damping characteristic and introducing inconsistency under braking. The FSS-015 kit restores the SC82's fork to the factory damping specification defined by Honda and SHOWA — critical whether you are threading through traffic or carrying maximum corner speed at a track day. The 43 mm inner diameter seals are sized for the SC82's inverted SHOWA BPF fork tubes, and the 11 mm height ensures correct seating depth in the fork lower leg without shimming or spacers.
