DescriptionThe whole story▼

The Ninja 400 shares its 399 cc twin with the Z400, and it was a common choice for A2 riders as well as for small-capacity racing. Gilles lists the FCAP-04-B for it, a light, two-colour anodised fuel cap without a key lock.

Key Features

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

EX400G and EX400L

Two types are covered, the EX400G up to 2020 and the EX400L from 2022. For a Ninja 400 first registered in 2021, compare the type code in the papers with these two before ordering.

Road Approval

For the Kawasaki Ninja 400, Gilles states that the FCAP does not require any approval, so there is no certificate to carry.

Scope of Delivery

One Gilles FCAP-04-B fuel cap for this model, black with a titanium-coloured centre as pictured. The FCAP-TOOL-01-B needed to open and close it is sold separately; one tool serves every Gilles FCAP cap, so a second cap on another bike needs no second tool. Keep the original cap and its lock in case the bike goes back to standard.

Fitting

Fit the cap with the tank nearly empty and the bike upright, in a ventilated place with no open flame or sparks nearby. Follow the Gilles instructions for the screws and their order. Check afterwards that the cap closes fully and that no fuel escapes when the bike is leaned over on its stand; after the first ride, check once more.
