The Jet Ski ULTRA LX comes equipped with the high-performance hull of the ULTRA 310 Series.

Loaded with technology from Kawasaki’s championship winning machines, the race-developed hull handles with precision and stability, with a high level of seaworthiness.

In addition to contributing to the Ultra LX’s improved handling in both rough and calm water, the idealised strength balance helps realise a much lighter package. A revised steering nozzle also contributes to the much lighter handling.

A generous three-seater that encourages family fun


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

The hull 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.


Ridges across the bottom of the bow, Kawasaki Splash Deflectors deflect water splashing forward from under the hull.

The 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, enhancing ride comfort.


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 310X ensure high durability and reliability.

The Ultra LX features a normally aspirated, fuel injected engine that is designed to deliver eye-opening performance and combine it with incredible economy.
