Lotus' Colin Chapman famously said that the best way to build a car was to "simplify, then add lightness." I'm not sure that's what Kawasaki did with its new STX 310R PWC, though, as it took what seems to be a version of its simple supercharged superbike engine, the same found in the Ninja H2 and Teryx H2, and then enrobed it in the trappings of the brand's Jet Ski lineup, and that's about it.
But unlike those other Kawasakis with their meager 206 and 250 horsepower, respectively, the STX 310R gets the engine's full potential, i.e., 310 rampaging horses intertwined with the hull. That's 310 horsepower in a machine that weighs about the same as my left shoe. 310 horsepower in a machine that generally goes where speed limits aren't a thing. 310 horsepower at your beck and call underneath your right fist, where sharks and more roam.
