1500cc In-line Four engine with TVS Roots supercharger delivers highest output in Jet Ski history: 310 PS


Twin Vortices Series (TVS) Roots supercharger, featuring twin 4-lobe rotors, is highly efficient and quite compact. Boost pressure is 16.8 psi.


Electronic throttle valves manage high power output efficiently, enable numerous riding modes: Electronic Cruise Control. Fuel Economy Assistance Mode. One-touch 5 mph Mode. Smart Learning Operation (SLO)-Mode


Loaded with technology from Kawasaki’s championship winning machines, the race-developed hull handles with precision and stability, with a high level of seaworthiness – and at speeds from idle to its impressive top end. Specifically designed to handle the enormous output from the supercharged engine, the hull achieves a balance of strength and light weight.


Feedback from Kawasaki’s numerous IJSBA championship winning racing machines contributed to a hull specially designed to cope with the engine’s massive output while offering high stability and responsive handling in both calm and choppy-water conditions.


Instrumentation accommodates the engine’s various riding modes, as well as a new Current Fuel Consumption (measured at 1 second intervals) function. External Water Temperature, Air Temperature, Clock, Time, Trip, Hour Meter, Tachometer (digital display or bar graph), Speedometer, Max Speed functions are available as before. * Instrument panel position and cockpit visor design were selected to ensure high visibility.


The post-style handlebar is similar to the kind found on Kawasaki’s KX450F flagship motocrosser, although this ’bar offers even greater adjustability Handle position is adjustable, both for height and forward/rearward position. A total of 12 positions are available; 18 if the optional handlebar holders are included.


The ULTRA 310R is equipped with a new sport seat designed specifically for hard sport riding. The seat shape flares less at the thighs than the standard seat of the ULTRA 310X. This makes it easier to grip the seat with the knees when stand-up riding in rough water. Textured material, similar to that used on KX motocrosser seats, contributes to a racy appearance.
