Kawasaki Jet Ski Ultra LX

Combining the hull from the ULTRA 300LX and a responsive 160 PS engine with good fuel economy gives the new ULTRA LX an appealing blend of sporty and comfort performance. The new hull offers excellent handing in both rough and calm water conditions. Equipped with the Luxury seat and a number of other flagship features, the 2020 ULTRA LX ensures its passengers travel in the luxury and comfort befitting the LX name.

The ULTRA LX is equipped with the LXuryseat, a scalloped seat designed for enhanced cruising comfort. Contoured for a good ergonomic fit, the LXuryseat offers ultra-comfortable accommodation for three. The seat’s steps can be compressed from above when sat upon, allowing riders to shift rearward during strong acceleration. In rough conditions, riders can sit on the steps, allowing the thick, impact-absorbing padding to do the work otherwise left to thigh muscles.


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 power of the supercharged engine. Two separate keys (one for SLO-mode, one for full-power operation) make it easy for operators to know which operating mode they are using.

Deep-V hull design enables a high bank angle, motorcycle-like turning performance. This reduces the lateral G-loads imposed on riders during turns, allowing them to better concentrate on riding. Measuring 22.5°, the idealised V-angle at the bottom of the hull helps prevent spin outs during sharp turns. As a result, the ULTRA LX delivers the neutral handling and turning characteristics for which Kawasaki JET SKI watercraft are famous.

Kicking out an impressive 160 PS at 7,500 rpm, the liquid-cooled, 1,498 cm3 In-line 4-cylinder Ninja supersport-based engine delivers the responsive performance that sport riders love. In spite of its high performance, this ultra-low emissions PWC easily clears the stringent CARB regulations. Engine strengthening items borrowed from the powerful ULTRA 300X ensure high durability and reliability.

Developed based on feedback from Kawasaki’s race machines, this pump was specially designed to deliver incredible acceleration, stable output and good “bite,” even when riding in rough water. Using another trick borrowed from the ULTRA 300X engine, the jet pump drive shaft is supported using double bearings. A new shaft nut holds the shaft in place, preventing any forward movement. The result is increased reliability as well as greater durability.

Ridges across the bottom of the bow, Kawasaki Splash Deflectors deflect water splashing forward from under the hull. A fourth splash deflector mounted at the top reduces spray during high-speed turns. Whether turning or blasting straight ahead, at high speeds or low, the Quattro KSD minimises spray, allowing greater rider concentration.

The models of the ULTRA 310 Series (except the ULTRA 310R – please see below) feature a 5-way adjustable handle that suits a wide range of riders and riding styles, allowing either standup or sit-down riding.
