DescriptionThe whole story▼

Keeping your forks in peak condition begins with seals that hold their integrity mile after mile. The K-Tech FSS-015 oil seal kit for the Kawasaki ZX-10 R/RR uses genuine SHOWA-NOK seals — the exact specification trusted by leading Japanese suspension manufacturers as original equipment — so you get a precise, long-lasting fit every time the front end is serviced.

Key Features

  • SHOWA-NOK series seals deliver the all-day reliability and consistent performance demanded by both road and track riding.
  • Dimensionally identical to the Kawasaki factory seals: 43.00 mm inner diameter, 54.00 mm outer diameter, 11.00 mm height — no modification or adaptation required.
  • Complete two-seal kit covers both fork legs in a single purchase, making routine maintenance straightforward and efficient.
  • Precision fit eliminates oil weeping past the seal, preserving fork damping performance and chassis stability under hard braking and cornering.
  • Direct OEM replacement means installation follows the standard service procedure without any guesswork.

Quality You Can Rely On

NOK is the benchmark name in suspension sealing technology throughout the Japanese motorcycle industry. Produced to exacting tolerances from high-grade elastomer compounds, these seals resist the heat cycles, fork oil chemistry and sustained loading that degrade inferior aftermarket alternatives. The result is consistent fork action from the first ride after a service to well beyond the next one.

Road and Track Suitability

Whether the ZX-10 R is your daily road weapon or a dedicated Superbike-class track tool, fork seal integrity is non-negotiable. A weeping seal does not just leave an oil film on the lower leg — it gradually robs the fork of its correct oil level, softening damping progressively until handling becomes unpredictable. Fitting the K-Tech FSS-015 kit restores the fork to its intended specification and keeps it there.
