    2015 Kawasaki Ultra LX..

    2015 KAWASAKI JET SKI® ULTRA® LX      Water-borne Luxury, Performance and Efficiency


    The Jet Ski® Ultra® LX personal watercraft hits all the right marks when it comes to offering performance and luxury. It’s an all-around watercraft that matches fun and excitement with performance and luxury. The Ultra LX delivers excellent performance for enthusiasts, with tremendous comfort and cavernous storage capacity.


    • Deep-V hull provides better handling
    • Industry-leading storage capacity lets you bring all the gear you need
    • Largest fuel tank in class keeps the fun going longer
    • Scalloped LXuryseat enhances comfort
    • Five-position adjustable steering adapts to a variety of riders
    • Splash deflectors minimize spray in a variety of conditions
    • Retracting rear boarding step makes it easy to climb aboard
    • SLO (Smart Learning Operation) allows engine speed to be limited for novices
    • Kawasaki Smart Steering® (KSS®) system gives turning assistance



    The comparison to Kawasaki’s ultimate personal watercraft is an apt one, because the Ultra LX incorporates many of the advanced features and technologies from the supercharged Ultra 310 family.

    The advanced hull, for example, is a fiberglass-reinforced design that allows serious maneuverability thanks to its 22.5-degree deep-V shape.


    There’s Ultra 310 technology in the propulsion system. The jet pump, driveshaft and nozzle share the basic design of the 310 series, for example. This advanced system converts the horsepower of the Ultra LX into immediate yet controllable thrust via a large-diameter 155mm jet pump. Combined with a steering nozzle designed for light handling, the system delivers consistent performance, and plenty of bite, even in rough water.

    Everything Kawasaki knows about high-tech engine building goes into the super-efficient powerplant of theUltra LX. The reliable 1,498cc inline-four four-stroke engine is based on the one powering the legendary Ninja®ZX™-14R sportbike – the most powerful production sportbike on the planet.

    It delivers stunning power – 160hp[1] and nearly 1,000 pounds of thrust – plus manageable throttle response thanks to its DOHC cylinder head design, lightweight pistons, advanced fuel injection system, efficient intake tracts and optimized exhaust.

    The big inline-four is also surprisingly fuel efficient, which means you’ll do a lot of exploration and wave-whipping before the extra-large 20.6-gallon fuel tank runs dry.



    Another reason you can disappear all day on the Jet Ski Ultra LX watercraft is its massive 60-gallon storage capacity, which means food, drinks, supplies, clothing and all kinds of gear can be easily stowed.

    The on-board comfort for the rider and passengers is exemplary. There’s a soft, LXuryseat with support bolsters, five-position steering that allows the rider to dial-in the right position while standing or sitting, and splash deflectors minimize spray to help keep everybody dry. There’s also a large, easy-to-read LCD display that provides a multitude of key digital information, including water and ambient temperature. Its easy-to-use reverse lever offers light operation as well.


    For optimum maneuverability, the Ultra LX personal watercraft gets electronic turning assistance via its Kawasaki Smart Steering® system. KSS® features an on-board microprocessor that is linked to a steering sensor. When the handlebar is fully turned in either direction, and the engine RPM drops below a designatedspeed – such as when the throttle is released at speed – the microprocessor activates the system, raisingengine speed to provide thrust for maneuvering.

    There’s no end to the fun and exploration you can generate on a watercraft as performance-oriented, practical, fun and comfortable as the 2015 Ultra LX. Here’s what one journalist remarked after getting off an Ultra LX: “It unlocks parts of the ocean and planet you simply couldn’t get to before. And that’s an amazing and wonderful thing.” We couldn’t agree more.



    Kawasaki Genuine Accessories, such as a Protective Cover, Bumpers, Anchor, etc, are available atauthorized Kawasaki dealers.

    Composite Hull

             The design incorporates feedback from Kawasaki’s IJSBA championship-winning racing machines for excellent tracking and responsive handling in both calm and rough water conditions

             Delivers the neutral handling and turning characteristics that made Kawasaki Jet Ski® personal watercraft famous, yet the hull enables a high bank angle for motorcycle-like turning performance with reduced side g-loads imposed on riders during turns

             The 22.5-degree V-angle at the bottom of the Ultra LX hull helps prevent spinouts during sharp turns and provides a smoother ride in rough water

             Placing the battery near the center of the machine optimizes weight balance in the hull and frees space inside the engine bay to help maximize storage capacity

             The bottom of the hull slants steeply upwards from the center section to the bow, allowing the Ultra LX to penetrate swells and waves with less shock. This allows the hull to push through waves rather than bounce over them at higher speeds

             Integrated sponsons extend from the hull, providing wallow-free straight-line performance and contributing significantly to the excellent high-speed maneuverability of the Ultra LX, while helping to retain a narrow hull design


    Ride Plate

             Features a groove from the center to the rear of the ride plate to enhance straight-line tracking


    Quattro KSD

             The Kawasaki Splash Deflector (KSD) on the Ultra LX 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 running straight ahead at high or low speeds, the Quattro KSD minimizes spray, allowing greater rider concentration


    Kawasaki Smart Steering® and Smart Learning Operation Mode

             Kawasaki Smart Steering® (KSS®) monitors steering input and engine speed and, when certain conditions are met, raisesRPM to initiate a desired turn, helping new riders to better enjoy the performance of this remarkable machine

             Smart Learning Operation (SLO) allows novice riders to become familiar with the handling and response of this Jet Ski watercraft at a more relaxed pace before unleashing the full performance of the Ultra LX
