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.

Like that of its predecessor, the deep-V hull design enables a high bank angle, motorcycle-like turning performance.

The ULTRA 310R is equipped with a new sport seat designed specifically for hard sport riding. The moderate contour of the seat supports the rider’s hips, offering enhanced lower body support for hard sport riding.

This handy mode is used in “No Wake” zones. It regulates engine speed to maintain a forward speed of 5 mph (8 km/h).

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.

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.

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.

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 KSS (Kawasaki Smart Steering) supplementary steering system is designed to assist new riders as they learn turning and manoeuvring of a personal watercraft.
