For many watercraft fans, maximum this and ultimate that aren’t always necessities. Sometimes, a high-end, high-power PWC that’s focused more on balance and efficiency is just right – and for these value- and performance-oriented enthusiasts, Kawasaki’s new-for-2012 Jet Ski® Ultra® LX may well be the perfect boat.

New For 2012

• Kawasaki’s latest deep-V hull design is lighter and stronger than before, and offers improved stability and handling

• More durable and higher-output 155mm jet pump

• New digital LCD cockpit display is easier to read and offers more information than before

• 2012 version is nearly 43 pounds lighter than last year’s Ultra LX

• More durable con-rod bolts and crankshaft bearing inserts, and more rigid crankcases

• Revised Electronic Control Unit (ECU) for lower exhaust emissions

• 20mm shorter steering nozzle allows lighter handling

• More accurate speed sensor

• Redesigned reverse lever and hatch lock for easier operation

Key Features

• Stable and sporty handling in all water conditions

• Deep-V hull provides better grip for racing-like performance

• Industry-leading storage capacity lets you bring all the gear you need

• Largest fuel tank in class keeps the fun going longer

• Scalloped luxury seat enhances comfort during high-speed cruising

• Five-position adjustable steering adapts to a variety of riders

• Splash deflectors across the bottom of the bow minimize spray in a wide variety of conditions for greater rider concentration

• Retracting rear boarding step makes it easy to climb aboard

1,498cc, Four-stroke Engine

• Strong engine provides excellent low and mid-range torque

• Dual overhead cams (DOHC) are light and compact for less valve train inertial mass

• Four large valves per cylinder provide better intake and exhaust flow for optimum torque and power

• Intake and exhaust valve lift as well as timing are set to reduce exhaust emissions

• Intake tract designed for maximum performance

• Waterproof ECU and ignition coils protect the ignition system from electrical shorts

• Unique semi-dry sump oil system lowers the crankshaft in the engine, eliminates the need for scavenging pumps, and keeps the oil in the sump instead of flooding the crankcase if the craft capsizes

• Large capacity airbox lowers engine noise and improves air intake flow

Fuel Injection

• Large single 60mm throttle body

• Digital fuel injection provides great throttle response, smooth engine performance and quick acceleration, as well as easy starting and excellent fuel economy

• Four-orifice, high-flow fuel injectors provide efficient combustion


• Large-diameter 155mm jet pump efficiently converts the engine’s horsepower into thrust

• Developed based on feedback from Kawasaki’s race machines, this pump is designed to deliver stable output and good “bite,” even when riding on rough water

• The large, sophisticated three-blade impeller unit delivers both high speed performance and quiet operation

• Eight-vane intake guide smooths and regulates the flow of water from the impeller for efficient and powerful propulsion

• The reverse lever is on the left side for easy operation while modulating the throttle with the right hand

Composite Hull

• Design incorporates feedback from Kawasaki’s IJSBA championship-winning racing machines for high stability 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’s 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

• Bottom of the hull slants upward steeply from the center section to the bow, allowing the Ultra LX to penetrate swells and waves with less shock. This provides extreme stability at low speeds, while allowing the hull to push through waves rather than bounce over them at a higher pace

• Integrated sponsons extend from the hull, providing stable, wallow-free straight-line performance and contribute significantly to the Ultra LX’s excellent high-speed maneuverability while helping to retain a narrow hull design

Ride Plate

• Features a groove from the center to the rear of the ride plate that enhances straight-line stability

Quattro KSD

• The Ultra LX’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 blasting straight ahead at high speeds or low, 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, raises rpm to initiate a desired turn, helping new riders 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

• Two separate keys, one for SLO mode and one for full-power operation, help prevent confusion over which setting is in use

Comfort and Convenience

• Luxury touring seat incorporates specific support areas for the rider and passenger to offer increased confidence and a more relaxing experience

• Five-way adjustable handlebars allow operation while standing or sitting for a wide range of riders

• Ergonomic deck design has plenty of legroom for rider-friendly seating accommodations

• A long rear boarding step makes it easy to climb onboard, and the step retracts inside the bumper to prevent damage

• A quick and easy under-hood hose connection allows easy flushing of sea water out of the engine

• Mirrors mounted on the upper deck facilitate opening of the hatch cover

Capacious Storage

• 60-gallon storage capacity is the largest in its class

• The large-capacity, fully sealed 58-gallon storage area is fitted with a detachable storage tray and has plenty of room for recreational equipment

• Glove box on the center console has a built-in drink holder with space for two drink bottles

• Compact storage area under the rear passenger seat is ideal for small items
