Suzuki Hayabusa Gen-2 45mm EFI Individual Throttle Bodies (Single Injection)
These Direct-to-Head (DTH) 45mm twin housing shaftless throttle bodies (ITBs) are engineered for Suzuki Hayabusa Gen-2 engines (2007–2020), including 1300R-K8 (2008), GSX-1300R-K9 (2009), and later K models. Designed to match the OEM cylinder port spacing and intake profile, they utilise four aftermarket fuel injectors (available separately) for enhanced fuelling capacity.
Machined from lightweight billet aluminium, these ITBs feature AT Power’s patented shaftless butterfly technology and knife-edged valves, delivering improved induction airflow, sharper throttle response, and increased engine performance.
