The 300R 4-Stroke is the highest performing engine in its class.

Custom Racing intake cam profiles and short intake manifold runners maximize 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 Optimization automatically adjusts fuel delivery for up to 10% improvement in cruise-speed fuel efficiency. All of this on 87-octane (90 RON) pump fuel while maintaining a comparable weight as it’s legacy two-stroke cousin.
