250R

DESCRIPTION

The 250R FourStroke pumps out 250 propshaft horsepower. The stout V-8 powerhead provides an astounding 53% increased displacement and up to 40% higher overall bottom-end torque than the legacy two-stroke 250XS it replaces. 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, while maintaining a comparable weight to the 250 XS.
