Vehicle Information
Kawasaki Jet Ski SX 650 Personal Watercraft (1987-1993)
The Kawasaki Jet Ski SX 650, produced from 1987 through 1993, is an iconic stand-up personal watercraft, known for its consistent core design. It was powered by a 2-stroke, 635cc vertical twin engine, delivering 52 horsepower, offering a dynamic riding experience. While offered as a single 650SX model without distinct factory trims, the series did undergo key mid-cycle updates. Models from 1987-1990 featured a 28mm Keihin carburetor and a front-left exhaust exit. From 1991-1993, Kawasaki upgraded to a 38mm Keihin carburetor and rerouted the exhaust to the rear, improving rider comfort. All models included an ignition system with a built-in rev limiter that activated at approximately 6,200 rpm. FAQ:
