Fullsix Carbon Airbox Cover BMW S1000RR K67 (2019-2026) – 245 Twill

Built for the track and engineered to the tolerances of professional motorsport, the Fullsix Carbon airbox cover transforms the BMW S1000RR K67 from a superbike into a genuine racing machine. Autoclave-manufactured from 100% carbon fibre in a deep 245 Twill weave, this direct OEM replacement sheds unsprung mass, refines aerodynamics, and announces intent before the throttle is even opened.

Key Features

• 100% autoclave-cured carbon fibre construction — no mixed fibres, no compromises in structural integrity under sustained high-RPM racing conditions
• 245 Twill weave pattern delivers the deep, purposeful motorsport aesthetic associated with factory race programmes
• Optimised airflow geometry improves induction efficiency and contributes to more stable high-speed aerodynamics
• Plug-and-play fitment replaces the OEM airbox cover directly — no cutting, drilling, or permanent modification required
• Available in Glossy, Matte, or Raw finish to suit a track livery, a stripped race build, or a custom respray
• UV-stable resin system resists yellowing and material fatigue across extended race seasons and outdoor storage
• Road approval (ABE — Allgemeine Betriebserlaubnis) currently in preparation, with street certification expected to follow

Track-Proven Construction

Fullsix produce their carbon components using the same autoclave process employed by factory race teams: pre-preg carbon fibre is laid under precise vacuum pressure and cured at elevated temperature, producing a void-free laminate with an exceptional strength-to-weight ratio. The result is a cover that is meaningfully lighter than the original plastic item, reducing the mass the S1000RR K67 carries between corners without any compromise in rigidity.

The 245 Twill weave is not merely cosmetic — the diagonal fibre orientation contributes to multi-directional load distribution, meaning the cover maintains its geometry even when subjected to the vibration, heat cycles, and airflow forces generated at sustained racing speeds. The finish is applied to the outer surface of the weave, so the part reads as a genuine carbon component rather than a painted substitute.

Finish Options

Three distinct surface treatments are available to match any build philosophy. The Glossy finish presents the twill pattern under a high-clarity lacquer, giving the engine bay a premium, competition-ready appearance. The Matte finish eliminates surface reflections for a more aggressive, uncompromising race aesthetic. The Raw finish leaves the carbon surface untreated, ideal for builders who wish to apply their own livery or integrate the cover seamlessly into a full custom fairing paint scheme.

Fitment and Compatibility

This airbox cover is developed specifically for the BMW S1000RR in K67 specification, covering all production years from 2019 through 2026. The geometry matches OEM mounting points exactly, so installation requires no modifications to the motorcycle's airbox, frame, or surrounding bodywork.
