Kawasaki Jet Ski Ultra 310LX

Kawasaki Jet Ski Ultra 310LX

The Premium model, the ULTRA 310LX is without question the head of Kawasaki’s JET SKI fleet. Metallic paint, chrome highlights and a unique deck mat pattern make it stand out visually even more than its Series brothers. But what truly sets it apart are its unique features: the new Jetsound audio system (a PWC world’s first), and its new LXuryseat covered with a new heat-resistant material making its debut in the PWC/motorcycle industry.

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


Hull balances strength and light weight to handle 310 PS output – High stability and responsive handling in both calm and rough water


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


The models of the ULTRA 310 Series (except the ULTRA 310R – please see below) feature a 5-way adjustable handle that suits a wide range of riders and riding styles, allowing either standup or sit-down riding.


For those who feel life is better with a soundtrack, and do not want to be without music when blasting across the water on a supercharged JET SKI, the new Jetsound audio system was made for you! System is compatible with iPod and iPhone, other smartphones, and other audio players that have stereo pin jack output. The system can even play music files from a USB memory stick


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.


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.


Smart Learning Operation (SLO)-Mode function allows newer riders to become familiar with the handling and response of this JET SKI watercraft at a more relaxed pace before unleashing the full power of the supercharged engine. Two separate keys (one for SLO-mode, one for full-power operation) make it easy for operators to know which operating mode they are using.


The ULTRA 310LX is equipped with the LXuryseat, a contoured seat designed for enhanced cruising comfort. Shaped for a good ergonomic fit, the LXuryseat offers ultra-comfortable accommodation for three. Enhancing comfort on a hot day, the seat’s new cover is made from a revolutionary new material that resists heat gain, so the seat does not get as hot after sitting in the sun between rides.
