Kawasaki has recently unveiled what it hails as the most powerful jet ski ever built -- the 2011 Kawasaki Ultra 300X. Kawasaki has also just launched the new 2011 Ninja ZX-10R superbike but this time, the Japanese manufacturer is causing a stir among jet ski enthusiasts. The Ultra 300X is powered by a 300hp 1,498cc inline-four DOHC engine and it features a deep-V hull for enhanced stability and cornering performance. Kawasaki completely redesigned the Ultra 300X jet ski for 2011.

It is equipped with an all-new supercharger and Kawasaki's Electronic Throttle Valve system. The 300X jet ski is available in a range of riding modes such as the Smart Learning Operation mode, which enables new riders to learn how to ride the 300X jet ski at a more relaxed pace. This system makes this possible by having separate keys that dictate power to the ECU.

The rider’s comfort is improved considerably over the 260X model with the use of revised ergonomics. The handlebar is five-way adjustable to suit a range of riders and riding styles. Meanwhile, its grips have been adjusted to be nearly an inch wider to make way for the all-new handlebar switch assemblies.
