DescriptionThe whole story

The Bonamici Racing quick-release fuel cap for the Kawasaki ZX-4RR (2023–2026) delivers a genuine performance upgrade where it counts most: eliminating 70% of the stock cap's weight and replacing a fiddly OEM fitting with a precision quarter-turn mechanism that opens and closes in an instant. Whether you are chasing lap times on track or simply want lighter, sharper hardware on your ZX-4RR, this is the definitive replacement.

Key Features

  • 70% weight reduction over the original Kawasaki fuel cap — a meaningful saving on a lightweight four-cylinder machine.
  • Quarter-turn quick-release mechanism allows near-instant tank access — invaluable during pit stops and routine refuelling alike.
  • Direct OEM replacement with no modification required — bolts straight in using the supplied fixing kit.
  • Rubber seal included in the box ensures a fuel-tight, rattle-free fit from day one.
  • Available in eight anodised finishes — black, silver, gold, orange, red, blue, green and bronze — to complement any ZX-4RR livery.
  • Part number FC170 — a dedicated Bonamici Racing fitment engineered specifically for the 2023–2026 ZX-4RR chassis.

Built for the ZX-4RR

Bonamici Racing design their accessories around real-world track and road use, and the FC170 is no exception. The quarter-turn locking system is positive and secure — there is no risk of the cap working loose under vibration — yet it releases immediately when you need it to. The substantial weight saving is particularly relevant on the ZX-4RR, a motorcycle already lauded for its class-defying power-to-weight ratio. Stripping mass from a non-structural component like the fuel cap is exactly the kind of marginal gain that adds up over a race weekend.

Fitment and Compatibility

Designed and manufactured exclusively for the Kawasaki ZX-4RR across all model years from 2023 to 2026. No adapters or brackets are required; the cap replaces the OEM item directly using the included bolt kit and rubber seal.
