DescriptionThe whole story▼
A direct-fit carbon airbox cover that slots straight onto the BMW S1000RR K67 without modification — the Carbonin CB4426 is the kind of upgrade that earns its keep on both road and track. Crafted from high-grade carbon fibre, it delivers a meaningful reduction in weight over the standard plastic unit while channelling intake air more efficiently to keep the S1000RR's engine breathing cleanly at every throttle opening.
Key Features
- High-grade carbon fibre construction combines exceptional rigidity with a lower weight penalty than the OEM plastic cover
- Optimised airflow geometry guides intake air more efficiently into the airbox, supporting improved engine response and output
- Precision-moulded for an exact OEM-style fit on the BMW S1000RR K67 (2019-2022) — no trimming or adapting required
- Straightforward installation using standard workshop tools, making it a practical daily upgrade as well as a track-day mod
- SBK-derived design meets the durability demands of repeated high-temperature, high-vibration use
Built for Everyday Use and Beyond
Where some carbon components are track-only show pieces, the Carbonin CB4426 airbox cover is engineered to serve reliably every time you throw a leg over the S1000RR. The carbon fibre layup is finished to a consistent weave pattern that looks purposeful without demanding fussy maintenance, and the cover's resistance to heat and vibration means it holds its shape across long road sessions just as readily as it does during an afternoon at the circuit.
The weight saving over the standard item is modest on its own, but combined with other Carbonin fairing components it contributes to a cumulative reduction that riders notice in steering feel and responsiveness. For owners who want measurable improvement without a complicated installation, this airbox cover represents an accessible starting point.
Race-Derived Engineering
Carbonin developed the SBK range alongside competition programmes, so the internal profiles that govern how air enters and flows through the cover are shaped by real data rather than aesthetics alone. The result on a road-registered S1000RR K67 is an intake tract that complements the bike's existing fuel injection mapping and helps the engine perform closer to its design potential across the rev range.
