Jet Ski Ultra 250X
Tokyo, November 9, 2006 — Kawasaki Heavy industries, Ltd. announced today that it will release its Jet Ski Ultra 250X, the ultimate personal watercraft and first model equipped with a Roots type supercharger,* in March 2007.
Fitted with a Roots type supercharger, the Jet Ski Ultra 250X’s liquid-cooled 1,498 cm3 in-line 4-cylinder engine ensures a stable supply of high-pressure intake air, even at low rpm, to significantly increase maximum boost pressure. This high-performance engine along with its newly designed hull ensures superior acceleration and handling under any wave conditions, making the Jet Ski Ultra 250X the ultimate super sports model designed for one to three riders.
In addition to the Jet Ski Ultra 250X, Kawasaki will also release the Jet Ski Ultra LX, an all-round sports cruiser fitted with the same hull as the Jet Ski Ultra 250X and the same engine found in the Jet Ski STX-15F.
Both models comply with not only the Japan Boating Industry Association’s voluntary emissions control standards but also the emissions standards of the US EPA (Environmental Protection Agency) and CARB (California Air Resources Board), which has the strictest emissions standards in the world.
* Driven by a belt connected to the engine's crankshaft, the Roots type supercharger employs two counter-rotating lobed rotors that spin together to push air out.
