SUPERCHARGED PERFORMANCE

SUPERCHARGED PERFORMANCE

A 1,498cc, inline 4-cylinder marine engine with supercharger and intercooler makes the Jet Ski Ultra 310R the most powerful production personal watercraft in the world. The high-tech Eaton Twin Vortices Series (TVS) supercharger boosts the compact powerhouse, delivering unprecedented performance that is sure to ignite the fun.

310 HORSEPOWER

310 HORSEPOWER

  • Heat-resistant plastic intake manifold is shaped to improved low-mid range power
  • Cast pistons feature additional ring land V-grooves for better oil retention
  • Hardened nickel 33.4mm intake and 28.3mm exhaust valves offer superior reliability
  • Two-layer oil cooler offers efficient cooling
  • Large cam chain increases reliability in a supercharged engine application
  • The reinforced crankcase adds to engine's durability and reliability

PERFORMANCE

PERFORMANCE

  • Check valve system between the cylinder jacket and water muffler that shuts water flow off above 2,000 rpm, to keep the cooling water inside the cylinder jacket for optimum cooling performance
  • Piston cooling oil jets increased from one jet per piston to two jets per piston for increased piston cooling
  • Crankcase oil return holes are designed for quicker oil return to the oil pan

**Horsepower measured in PS at the crankshaft under controlled conditions. Actual performance may vary.
DEEP-V HULL DESIGN

DEEP-V HULL DESIGN

The advanced deep-V hull design is inspired by Kawasaki's championship-winning race machines, with a 22.5-degree hull angle that allows the watercraft to penetrate swells and waves with great efficiency and less shock. Tuned sponsons help provide straight-line stability and high-grip performance in turns.
FUEL INJECTED

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.

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.
LARGE IMPELLER

LARGE IMPELLER

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.

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.
QUATTRO KSD

QUATTRO KSD

Ultra 310LX's Kawasaki Splash Deflector (KSD): The ridges across the bottom of the bow deflect water splashing forward from under the hull. A fourth splash deflector mounted at the top reduces spray during high speed turns. The Quattro KSD minimises spray, allowing greater rider concentration.
ADJUSTABLE HANDLEBARS

ADJUSTABLE HANDLEBARS

Handle position is adjustable for height and forward / rearward position. A total of 12 positions. Riders can choose from three height positions (STD / 5mm up / 10mm up) - adjusted using 5mm washers. Two handle bar slots and reversible holders offers four forward / rearward positions. Optional handlebar clamps add another six positions. The stainless steel handle is electropolished with a bar pad fitted.
SPONSONS

SPONSONS

Sponsons extend from the hull to provide stable straight line performance (e.g. porpoising from start is minimised) and retain the narrow design. Sponsons contribute to the superb manoeuvrability when changing direction (particularly at higher speeds).
ELECTRONIC TRIM CONTROL SYSTEM

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

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.
MULTIPLE RIDING MODES

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.
PERFORMANCE

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

THE SPORT SEAT

THE SPORT SEAT

The seat specifically designed for hard, sport riding. The contour of the seat supports the rider's hips and the seat shape is slim at the thighs. This makes it easier to grip the seat in standing ride position. Textured material adds to the grip and race character.
INSTRUMENT PANEL

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.
EASY TO RIDE

EASY TO RIDE

The ULTRA 310R has electronic Smart Learning Operation (SLO) system which can be programmed to speed-limit the engine. This is to assist novice riders in mastering their riding technique without worrying about excessive speeds. Two separate keys, one for SLO mode and one for full-power operation. Kawasaki Smart Steering (KSS) monitors steering input and engine speed to intelligently raises rpm to assist turning.
