DescriptionThe whole story

On track, thermal management is a performance variable, not just an engineering footnote. This Carbonin carbon air duct, part number CB4071, is purpose-engineered for the large SBK/Kit radiator on the BMW S1000RR K67 (2019-2022), channelling airflow with precision to keep coolant temperatures in check through prolonged high-load sessions. Where stock solutions compromise on weight and airflow geometry, this component does neither.

Key Features

  • Formed from high-grade carbon fibre for an exceptional strength-to-weight ratio that directly benefits lap times
  • Optimised duct geometry directs air efficiently through the large SBK/Kit radiator core, improving cooling performance under sustained race conditions
  • Dimensionally matched to the SBK/Kit radiator fitted to the BMW S1000RR K67, ensuring a precise, rattle-free fit with no modification required
  • Race-developed construction meets the durability demands of professional superbike competition
  • Straightforward installation with no specialist tooling required

Racing-Grade Construction

Carbonin has built its reputation supplying teams and privateer racers competing at the highest levels of superbike motorsport. The CB4071 air duct is a direct product of that environment. Carbon fibre construction keeps mass to an absolute minimum while providing the structural rigidity to hold its aerodynamic profile at speed and under engine bay heat. Unlike plastic alternatives, it will not distort or fatigue over a season of intensive use.

Cooling Performance on Track

The duct's primary job is directional: it takes the ram air entering the fairing and guides it squarely through the radiator core of the oversized SBK/Kit cooler, rather than allowing it to spill around the edges. The result is a measurable improvement in heat dissipation during the kind of sustained high-rpm running that characterises superbike racing — less thermal stress on the engine, more consistent power delivery, and greater confidence when the ambient temperature climbs on a summer race day.

Fitment & Compatibility

This air duct is designed exclusively for the BMW S1000RR K67 fitted with the large SBK/Kit radiator. It is not compatible with the standard road radiator. Confirm your radiator specification before ordering.
