310 HORSEPOWER SUPERCHARGED ENGINE
The 1,498cc, liquid-cooled inline four-cylinder engine makes 310 horsepower via a low mechanical loss design and improved efficiency. The Eaton TVS constant-displacement supercharger and liquid-cooled intercooler provide instant and consistent boost for outstanding performance throughout the rev range.
High-flow fuel injectors with 4 orifices are fitted to complement the increased power output and to improve combustion efficiency. A single throttle body is used with a bore diameter of 60 mm.
Efficiently cools high-pressure intake air – cooler air is denser and makes more power. Liquid-cooled intercooler design maintains consistent thermal performance.
To suit the 160 mm jet pump, the ULTRA 310X gets an impeller designed to efficiently convert all the extra power into forward thrust. The pump impeller features a super-efficient 3-blade design that gives the 310X great initial acceleration.
The wide rear deck behind the seat offers plenty of room to set up gear for water sports and facilitates getting back on board from the water. A long rear boarding step makes it easy to climb on board, and the step retracts inside the bumper to prevent damage.
Ultra 310X’s Kawasaki Splash Deflector (KSD): The ridges across the bottom of the bow deflect water splashing foward from under the hull. A fourth splash deflector mounted at the top reduces spray during high speed turns.
Whether turning or blasting straight ahead, at high speeds or low, the Quattro KSD minimises spray, allowing greater rider concentration.
A groove running from the centre to the rear of the ride plate makes it easier to hold a straight course when running straight ahead.
The handlebars are 5-way adjustable and suit a wide range of riders and riding styles and allows comfortable stand-up or seated riding positions.
The redesigned left side reverse control is even easier to use.
STRONG, LIGHT HULL DESIGN - SUPERB IN CALM AND ROUGH WATER
Designed to emulate the performance of Kawasaki’s IJSBA championship-winning race machines, the reinforced inner bow is extremely light with ample strength to handle the engine’s power output.
Exemplary straight-line tracking and responsive handling in both calm and rough-water conditions set performance benchmarks for the class. The lower hull is specially designed to distribute the engine and power delivery loads over a wide area.
Deep-V hull design enables a steep bank angle for motorcycle-like turning performance. This reduces the lateral G-loads imposed on riders during turns, allowing them to better concentrate on riding. The 22.5° V-angle at the bottom of the hull helps reduce unwanted spinouts during sharp turns. This all assists in delivering the neutral handling and turning characteristics for which Kawasaki JET SKI watercraft are famous.
The bottom of the hull slants upward steeply from the center section to the bow, so the 310X can penetrate swells and waves with less shock, pushing through waves rather than bouncing over them at high speeds. Integrated sponsons extend from the hull, providing wallow-free straight-line performance and contributing significantly to the 310X’s excellent manoeuvrability while helping to retain the narrow hull design.
Sponsons extend from the hull to provide stable straight line performance (e.g. porpoising from start is minimised) while helping to retain the machine's narrow overall design. They also contribute significantly to the superb manoeuvrability when changing direction (particularly at higher speeds).
To effectively convert the 310 PS output into thrust, the Ultra 310X utilises a, large 160mm jet pump, designed using eight guide vanes. The pump delivers superior “traction” in rough water conditions and significantly contributes to the Ultra 310X’s mind-boggling acceleration.
The pump is designed to deliver consistent output and good “bite” even in rough water conditions. The pump impeller features a super-efficient 3-blade design that gives the 310X greater initial acceleration and the eight-vane intake guides and regulates the flow of water to the impeller for consistent, efficient and powerful propulsion.
ø88mm steering nozzle, designed to be short and slim, ensures a light steering load. Handling feels light despite the high power output.
The Ultra 310X features a 4-into-2-into-1 powerboat-style exhaust system, which routes the exhaust pipe upwards. This allows the smoothest flow for exhaust gases, maximising exhaust efficiency.
ELECTRONIC TRIM CONTROL SYSTEM
Electronic Trim Control System allows the rider to control the angle of the jet pump nozzle to suit water surface conditions and riding style.
Adjustment range is plus or minus 8 degrees from standard.
ELECTRONIC CRUISE CONTROL
IMPROVED Fuel Economy Assistance mode revised for significant fuel savings and increased range. Convenient electronic cruise control smoothly holds a set speed from 8 kph up to top speed.
One-touch, push-button 8 kph mode allows hassle-free no-wake zone riding and the economical Riding Indicator mode can be viewed on a graph on the LCD info screen.
LARGE CAPACITY STORAGE
The huge front storage compartment comes with removable tray combined with a centre console storage area.
- Large-capacity, fully sealed storage area with detachable storage tray offers ample room for recreational equipment
- Compact integrated underseat storage area is ideal for small items like a ski rope
- Total storage capacity of 212L on the ULTRA 310X
MULTIPLE RIDING MODES
The ECU controlled ETV allows multiple riding mode options to be activated with the touch of a button. 8 kph mode conveniently regulates rpm to maintain constant speed in no-wake zones and cruise control fixes speed at a specified level for convenient long distance touring.
COMFORT AND CONVENIENCE
Roomy three-passenger seat offers ample support plus all-day comfort whether riding stand-up solo, seated or with passengers. The passenger handrail on the Ultra 310X is located to a more ergo-friendly location to help reduce passenger fatigue and features a redesigned handle for better grip. The optimally curved mirrors have been designed for a wider rear view and are mounted to the upper deck via new brackets
An ergonomic deck design gives plenty of legroom and the left-side reverse lever is ergonomically designed for easy operation. At the end of the day on the water a quick and easy hose connection allows a simple method to flush sea water out of the engine.
TWIN VORTICES SUPERCHARGER
Four-lobe, constant-displacement design offers significant performance increase over standard roots-type unit. The system force-feeds the engine two liters of air with every revolution, providing a constant supply of high-pressure intake air at all rpm. The compressed air is delivered continuously, not in waves, for smoother power delivery.
The supercharger produces large amounts of boost, even at low rpm, for instant and powerful acceleration right off of idle. Provides a flat and linear torque curve with mellifluous, lag-free power across the entire rev range. This system produces more low-rpm boost than competitive or aftermarket systems, with a maximum of 17 psi of boost pressure.
LCD screen features a face design that’s easy to read. The instrumentation includes a fuel consumption function, a boost meter scale, riding modes, external water and air temperature, clock, time, trip and hour meters, tachometer (in digital or graph displays), speedometer and max speed functions.
Eco Indicator shows the rider when the speed and throttle opening is in the 310LX’s most efficient range. The Kawasaki Eco Mode reduces and smooths engine performance while conserving fuel.
The ULTRA 310LX features Kawasaki’s innovative electronic Smart Learning Operation (SLO) system which can be programmed to speed-limit the engine to assist novice riders in mastering their riding technique without worrying about excessive speeds.
Smart Learning Operation (SLO) allows newer riders to become familiar with the handling and response of this JET SKI watercraft at a more relaxed pace.
Two separate keys, one for SLO mode and one for full-power operation, help prevent confusion over which setting is in use.
Kawasaki Smart Steering® (KSS®) monitors steering input and engine speed and, when certain conditions are met, intelligently raises rpm to help initiate a turn.
