The Kawasaki jet skis are the fastest, most powerful personal watercraft ever assembled. The Jet Ski riders seek powerful acceleration from an engine loaded with race technology and the precise handling and a runabout that can comfortably take the family out for a day of fun on the water. The Kawasaki Jet Ski Ultra LX provides everything a rider wants from a jet ski.
Ultra LX (engine)
With a powerful marine engine producing 160 horsepower, the Ultra LX is the largest and best-riding hull Kawasaki has ever produced, unrivalled range thanks to the industry’s largest fuel tank, and unmatched passenger accommodations and luxury features, the Ultra LX truly is a sport tourer without equal.
The Ultra LX’s new handling features are enough to satisfy most riders. However, it also delivers a major dose of acceleration performance. Its 1,498 cc DOHC in-line four cylinder marine engine is straight out of our top-of-the-line four-stroke runabout, the STX®-15F. Tuned to produce an impressive 160 hp, this engine provides the kind of power that made Jet Ski famous. The race-tuned propulsion features a large diameter 155mm jet pump combined with an oversize impeller and jet nozzle to turn the engine’s power into thrust. This results in superb “bite” on the water, which means stunning acceleration and enough speed to satisfy even the most demanding sport riders.
The foundation of the Ultra LX is the same deep V-hull found in Kawasaki’s new Ultra 250X flagship. It combines confidence-inspiring high-speed stability and excellent rough-water ride manners with responsive turning performance, thanks to a hull 250mm longer and 50mm wider than our current runabouts. The extra size—combined with new hull characteristics give the Ultra LX the rough-water handling and stability you need to enjoy the engine’s impressive performance to the fullest. That responsive, neutral handling also reduces rider fatigue when banked over during high-g cornering, and the hull’s deep 22.50 V-angle easily cuts through swells and waves for a confidence-inspiring ride when the conditions become challenging.
For those that want to ride the Ultra LX forever the Kawasaki team provided enough storage space. The Kawasaki Ultra LX has 53 gal of built-in storage capacity, plus a detachable storage compartment, a detachable drink holder with space for two drink bottles mounted on the center console and a compact storage area integral with the under-seat rear grip ideal for small items.
The Ultra LX is as easy-to-use as it is fast, luxurious and fun. It boasts a clever five-way adjustable steering handle to suit a variety of rider styles and sizes, making it possible to ride in either a standing or sitting position.
The first impression the Kawasaki Jet Ski Ultra LX lets after riding is good whit some minor exceptions. For example: the engine has a shudder at low speed that changes to a buzz at speed, because the nose rides low the ride is “wet” even at slow speeds, the reverse lever on the "good" side, but mechanism is a bit sloppy feeling. Although this minor “problems” the ride on the Ultra LX is fantastic, it cuts through waves perfectly.
Innovative concepts, modern sleek styling, superior handling, inspiring performance and affordability are all trademarks of the Kawasaki Jet Ski Personal Watercraft Range and the Ultra LX is no exception offering a combination of cutting-edge power, handling and luxury features that could set new standards for sport-touring personal watercraft.
Engine Strong, 1,498cc, four-stroke engine provides excellent low- and mid-range torque Intake tract designed for maximum performance Dual overhead cams (DOHC) are light and compact for less valve train inertial mass Four-valve cylinder head with large valves provide better intake and exhaust flow to improve torque and power Intake and exhaust valve lift as well as timing are set to reduce exhaust emissions Waterproof ECU and ignition coils protects 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 if the craft is capsized the oil stays in the sump instead of flooding the crankcase Large capacity airbox lowers engine noise and improves air intake flow
Fuel Injection Digital fuel injection provides great throttle response, smooth engine performance and quick acceleration, as well as easy starting and excellent fuel economy New, high-flow fuel injectors with four orifices are fitted to complement the increased power output and improve combustion efficiency Single throttle body features a large 60mm bore diameter
Jet Pump To efficiently convert the engine’s horsepower into thrust, an all-new, large-diameter 155mm jet pump was designed Developed based on feedback from Kawasaki’s race machines, this pump was specially designed to deliver stable output and good “bite,” even when riding on rough water The reverse lever has been moved from the right side to the left side for easier operation
Impeller To suit the new 155mm pump, a larger impeller was designed, offering improved thrust in the higher speed ranges The sophisticated three-blade unit delivers both high performance and quiet operation
Guide Vanes New eight-vane intake guide, to smooth and regulate the flow of water from the impeller for efficient and powerful propulsion Eight guide vanes provide superior “traction” compared to the older six-vane system
Ride Plate Features a groove from the center to the rear of the ride plate, to enhance straight-line stability
The new hull was designed based on feedback from Kawasaki’s IJSBA championship winning racing machines Offers a combination of high stability and responsive handling in both calm and rough-water conditions Delivers the neutral handling and turning characteristics that made the Kawasaki JET SKI famous The new super-strong hull is 250mm longer, to help provide stable handling performance Although it has a similar V-shape to the JET SKI STX-15F, the Ultra LX’s hull enables a high bank angle, for motorcycle-like turning performance. This reduces the side G-loads imposed on riders during turns The V-angle at the bottom of the hull has been changed to 22.5 degrees to help prevent spinouts during sharp turns and to provide a smoother ride in rough water To avoid concentrating heavy components towards the rear, the battery is located inside the front storage area near the center of the machine. This remote location also frees up space inside the engine bay
Bond Flange & Bumper The bottom of the hull slants upwards steeply from the center section to the bow, allowing the Ultra LX to penetrate swells and waves with less shock. At low speeds the result is extreme stability; at higher speeds it enables the hull to push through waves rather than bounce over top of them
Sponsons Newly developed sponsons extend further from the hull, providing stable wallow-free straight-line performance while helping to retain the narrow hull design. They also contribute significantly to the Ultra LX’s excellent maneuverability when changing direction (particularly at higher speeds)
Quattro KSD Ridges across the bottom of the bow, Kawasaki Splash Deflectors deflect water splashing forward from under the hull. To reduce spray during high-speed turns, the earlier triple splash deflector now has one more deflector mounted at the top. Whether turning or blasting straight ahead, at high speeds or low, the Quattro KSD minimizes spray, allowing greater rider concentration
Kawasaki Smart Steering®/SLO-Mode
Kawasaki Smart Steering (KSS®) is equipped to help new riders better enjoy the performance of this remarkable machine Smart Learning Operation (SLO)-Mode function allows newer 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, one for full-power operation) help prevent confusion over which setting is in use
Comfort and Convenience Five-way adjustable handlebars allow operation while standing or sitting and are designed to suit a wide range of riders Relatively narrow seat is comfortable for either stand-up or seated riding, as well as for passengers Ergonomic deck design gives plenty of legroom without necessitating a high seat, for rider-friendly seating accommodations A long rear boarding step makes it easy to climb on board, and the step retracts inside the bumper to prevent damage A quick and easy under hood hose connection allows nearly silent cleaning system to flush sea water used out of the engine Mirrors are mounted to the upper deck to facilitate opening of the hatch cover
