1990 Kawasaki 650SX Stand-Up Jet Ski – Rear Exhaust, Fully Built Performance

Description

The 1990 Kawasaki 650SX is a legendary stand-up platform prized for its durability, balance, and tunability. Built by Kawasaki, the 650SX remains a favorite among freestyle riders and performance enthusiasts—and this example is extensively upgraded.

This ski features a rear exhaust configuration with a Westcoast pipe, delivering crisp throttle response and strong mid-range pull. Handling and stability are enhanced by a wide tray, glassed-in front sponsons, and a trued bottom with raised chines—a proven recipe for predictable cornering and improved hookup.

Additional performance and reliability upgrades include a worked Keihin carburetor, Pro Watercraft Racing ride plate, Skat-Trak prop, custom Jet Trim mats, finger throttle, and a bilge pump. The result is a clean, well-built stand-up that runs very well and reflects significant time and care invested in the setup.
