DescriptionThe whole story▼

The Z500 SE is the better-equipped version of Kawasaki's A2 naked bike, and Gilles lists it from 2026. The FCAP-04-B is a matching upgrade for the tank: CNC-milled, two-colour anodised and light, according to Gilles.

Key Features

  • Low weight
  • Designed with experience from MotoGP and WorldSBK, according to Gilles
  • CNC-milled, two-colour anodised
  • Robust two-part construction

From 2026

Gilles' list names type EX450G. The tool FCAP-TOOL-01-B opens and closes the cap and is sold separately.

Road Approval

For the Kawasaki Z500 SE, Gilles states that the FCAP does not require any approval, so there is no certificate to carry.

Scope of Delivery

One FCAP fuel cap (FCAP-04-B) in black and titanium colour. Please order the FCAP-TOOL-01-B as well if you do not have one yet: without it the cap can be neither opened nor closed. The tool fits every Gilles FCAP cap, and the original cap can be kept for later.

Fitting

Follow the Gilles instructions step by step, with the fuel level low and the tank opening protected from dirt while the caps are swapped. Test the cap with the tool before you ride, and keep the tool within reach: without it, the FCAP does not open at the pump. If you are unsure about working on the fuel system, let a workshop fit it.
