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 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 to the 250 XS.
Best of all, the new 250R are backed by a three-year factory warranty.
