Used 2009 Kawasaki Jet Ski 800 JS800A9F

The 2009 Kawasaki JS800A9F SXR represents the final chapter in Kawasaki’s iconic line of two-stroke stand-up Jet Skis—a heritage that traces back to the original 1973 WSAA. Known for their raw performance and minimalistic design, stand-up Jet Skis like the JS800 SXR carved out a niche among freestyle riders, racers, and purists who appreciated skill over stability. At the heart of the 2009 SXR is a 781cc, twin-cylinder, 2-stroke engine, liquid-cooled and paired with a high-capacity axial-flow jet pump. It cranks out around 80 horsepower, offering strong holeshot power and a thrilling top-end for a hull this size. The engine is lively and responsive, particularly when set up with proper carb tuning and impeller upgrades. Riders accustomed to modern four-strokes might find the power delivery abrupt, but experienced riders will appreciate the instant throttle response. The SXR’s fiberglass-reinforced hull is long (over 7 feet) and stable compared to earlier JS models, making it more forgiving for intermediate riders while still nimble enough for aggressive cornering and freestyle tricks. It tracks well in chop and leans predictably into turns, though riders pushing the limits may still experience some porpoising without proper trim adjustments. The ride plate and intake grate are common aftermarket upgrades to dial in cornering grip and straight-line tracking.
