R FOR RACING AND RECREATION

The Kawasaki Jet Ski Ultra 310R personal watercraft (PWC) is the perfect prescription for adventurous riders seeking a pure adrenaline rush on the water. Based on Kawasaki's popular Jet Ski Ultra 310X, the new R-model draws from decades of Kawasakis championship-winning PWC racing experience to create the ultimate "sport" personal watercraft that's ideal for hard core recreation and racing. New to the flagship line-up is the Ultra 310R. The sport model is equipped with an 18 position handle bar and a sports seat - both designed for hard sport riding.

FUEL INJECTED

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.

LARGE IMPELLOR

To suit the 160 mm jet pump, the Ultra 310R 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 310R great initial acceleration.

QUATTRO KSD

The 310R's Kawasaki Splash Deflector (KSD) uses three bottom-mounted ridges and an additional deflector mounted at the top to deflect water splashing forward from under the hull. Whether turning or straight-line riding at any speed the Quattro KSD minimizes spray, allowing greater rider concentration.

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.

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.

INSTRUMENT PANEL

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 smoothes engine performance while conserving fuel.

JET PUMP

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 high-efficency 3-blade design that gives the 310X great initial acceleration and the eight-vane intake guides and regulates the flow of water to the impeller for consistent, efficient and powerful propulsion.

BEGINNER FRIENDLY

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.

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

AIR-TO-WATER INTERCOOLER

Efficiently cools high-pressure intake air - cooler air is denser and makes more power. Liquid-cooled intercooler design maintains consistent thermal performance.

REAR MOUNTING

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.

RIDE PLATE

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.

EXHAUST

The Ultra 300X 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.
