Engineered for the demands of track days and pit-stop efficiency, the Bonamici Racing quick-release fuel cap for the BMW M1000RR K66 delivers a 70% weight saving over the OEM unit while maintaining a secure, leak-free seal every time. The quarter-turn locking mechanism is the definitive upgrade for riders who refuse to compromise on speed or reliability.
Key Features
- 70% lighter than the original BMW fuel cap — measurable weight reduction right where it counts
- Quarter-turn quick-release mechanism for rapid, tool-free access during pit stops or refuelling
- Direct OEM replacement fit — no modification required for BMW M1000RR K66 (2021-2026)
- Supplied complete with fixing bolt kit and rubber seal for a safe, rattle-free installation
- Available in eight anodised colours to match or contrast your M1000RR livery
Purpose-Built for the M1000RR
Bonamici Racing designs every component around race-circuit realities. The FC040 fuel cap is no exception: the quarter-turn closure locks positively under vibration, while the machined body resists fuel vapour, heat and mechanical stress across the full racing season. The included rubber seal ensures the original fuel-system integrity is fully maintained — a critical safety consideration that distinguishes a proper racing accessory from an aftermarket imitation.
Precision Machining, Lasting Durability
Constructed from high-grade lightweight material and finished in a durable anodised coating, the FC040 resists corrosion and surface wear even when subjected to the fuel spillage and track grime that is unavoidable in competitive use. The choice of eight colour variants — black, silver, gold, orange, red, blue, bronze and green — means the cap integrates seamlessly with factory or custom paint schemes without drawing attention away from the bike's overall aesthetic.
Fitment and Compatibility
The Bonamici Racing FC040 is designed as a direct, drop-in replacement for the stock fuel cap on the following model:
