DescriptionThe whole story▼

Kawasaki gives its ZX-6R 636 cc instead of 600, a little extra that riders feel in the mid-range on the road. On a fast road ride the rear brake is used for small corrections, and Gilles' BRC-18-B gives its reservoir a machined cap.

Key Features

  • Cover for the rear brake fluid reservoir
  • One coloured ring each in silver, red and blue
  • The ring colour is your choice, as a visual accent
  • CNC-milled aluminium
  • Replaces the original reservoir cover quickly
  • No registration required, according to Gilles

ZX636J and 2026

Listed for the ZX636J of 2023 to 2025 and the 2026 model. The front reservoir cover BRC-14 is listed for the ZX-6R as well.

Road Approval

According to Gilles, the cover needs no approval on the Kawasaki ZX-6R. Nothing changes in the papers; what matters is a clean reservoir and a correctly seated cover.

Scope of Delivery

One CNC-milled cover for the rear brake reservoir, supplied with 3 coloured inserts. The cover replaces the original one, which you can keep in case the bike goes back to standard.

Fitting

Work with the reservoir horizontal and the bike held steady, and have a cloth ready for drips. Choose the ring colour first, then swap the covers and tighten the new one evenly. Wipe away any fluid at once, check that everything is tight and dry, and test the brake before riding off.
