Suzuki Bike Hayabusa Gen-2 Individual Throttle Bodies (ITBs) – 45mm / 48mm EFI
These Direct-to-Head (DTH) twin housing shaftless throttle bodies are designed to match the OEM cylinder port spacing and intake profile of Suzuki Hayabusa Gen-2 engines (2007-2020) including 1300R-K8 (2008), GSX-1300R-K9 (2009) and later models.
Manufactured from lightweight precision-machined billet aluminium, these throttle bodies feature AT Power’s patented Shaftless butterfly technology and knife-edged throttle valves. This design significantly reduces airflow restriction compared to conventional shafted throttles, delivering faster induction airflow, sharper throttle response, and increased engine performance.
These Direct-to-Head Hayabusa throttle bodies are supplied fully assembled with vacuum take-off fittings and are ready to bolt directly to the OEM intake connections.
