The ULTRA 310X is the “Standard” model of the Series – if any model with a 300 PS output can
be called “standard.” With its fantastic supercharged engine, nimble hull, great
flagship features and a comfortable two-piece seat that accommodates three
passengers, the ULTRA 310X sets the bar for standard commendably high.
Kawasaki Smart Steering/SLO-Mode
The KSS (Kawasaki Smart Steering) supplementary steering system is designed to assist new riders as they learn turning and manoeuvring of a personal watercraft.
All models of the ULTRA 310 Series feature a 5-way adjustable handle that suits a wide range of riders and riding styles, allowing either standup or sit-down riding.
This convenient system allows the angle of the jet pump nozzle to be controlled electrically (step-free adjustment range is +/- 8° from STD), making it easier for riders to adjust the attitude of the hull to suit water surface conditions and riding style.
Fitted with a supercharger and intercooler, the liquid-cooled 1,498 cm3, In-line 4-cylinder marine engine that propels the ULTRA 310 Series models forward with an exhilarating rush of acceleration produces an output much greater than a normally aspirated engine of the same displacement.
Electronic throttle valves efficiently manage the engine’s massive power output. They also make minute engine control possible, enabling easy switching between riding modes.
The all-digital instrumentation makes use of a single, highly legible LCD display. A revised design adds a higher quality image and increases visibility of some of the features.
This handy mode is used in “No Wake” zones. It regulates engine speed to maintain a forward speed of 5 mph (8 km/h).
