DescriptionThe whole story▼

The Z900's tank is broad and sculpted, and its filler cap sits right where the rider looks down at a standstill. Gilles lists the FCAP-04-B for every Z900 from 2017 to 2025, a CNC-milled, two-colour anodised cap that opens without the ignition key.

Key Features

  • Opened and closed with the FCAP-TOOL-01-B, sold separately
  • Keyless operation
  • Low weight
  • Designed with experience from MotoGP and WorldSBK, according to Gilles
  • CNC-milled, two-colour anodised
  • No registration required, according to Gilles

ZR900B to ZR900V

Covered are ZR900B (2017 to 2020), ZR900H / F / A2 (2021 to 2024) and ZR900V (2025).

Road Approval

No registration required, says Gilles: the FCAP goes on the Kawasaki Z900 without an inspection and without any change to the vehicle documents.

Scope of Delivery

The FCAP-04-B fuel cap for this model, finished in black with a titanium-coloured centre. The opening tool FCAP-TOOL-01-B is not included and has to be ordered once; Gilles makes it for all of its FCAP caps. Your original cap with its lock stays with you and can be refitted at any time.

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.
