The 300R FourStroke is the highest performing engine in its class. The naturally aspirated 4.6L V-8 provides an astounding 44% in increased displacement and up to 40% higher overall bottom end torque than the legacy two-stroke 300XS it replaces. Custom Racing intake cam profiles and short intake manifold runners maximise power throughout the rated speed range. An integrated oil cooler keeps oil temps down throughout the Racing exclusive 5800-6400 rpm operating range. Transient spark calibration boosts torque by 7% for unmatched acceleration. Advanced Range Optimisation (ARO) automatically adjusts fuel delivery for up to 10% improvement in cruise-speed fuel efficiency. All of this on regular 91-RON Unleaded fuel.
