1998-1999 Kawasaki Xi Sport Review
Kawasaki Xi Sport Hull
Kawasaki introduced the high-performance Xi Sport for the 1998 model year, as an upgraded version of the proven Super Sport Xi.
The Sport Xi inherited its SMC hull from its predecessor, which included a “step” on its keel intended to reduce bow spray.
Regarding dimensions, this deep-V platform measured 99.6 inches in length, 40.6 inches in width, and 37.2 inches in height.
Unlike the hull, the top deck of the Xi Sport had been slightly redesigned. Its handlebars were moved to the front for a more comfortable riding position. However, the ski lacked the innovative dashboard, which came standard on its predecessor.
Other features like the bow storage, 2-rider seat, 8.7-gallon fuel tank, and 2.4-quart oil tank were carried over without any changes.
In terms of color scheme, the hull and the top deck were covered with white Gelcoat, while the handlebar cover and column were painted black. These colors were complemented with green and purple decals on the 1998 model.
By 1999, the body of the ski remained white but it was dressed in a purple/black decal set. The seat, handlebar cover, handlebar column, and front storage lid were now a new, bright yellow color.
The dry weight of the Xi Sport was 408 pounds, which meant a 7-pound weight loss compared to the previous year’s model.
This was a big surprise since this revamped model now had a more powerful engine option.
Let’s drill into the details and talk about this engine detail!

Kawasaki Xi Sport Engine and Propulsion
The power source of the Kawasaki Xi Sport was a 2-stroke, 743cc, dual-carb, vertical twin engine rated at 80 HP. This advanced unit was also known as the “big-pin” 750 Kawasaki engine.
This 750 engine was inherited from the Super Sport Xi, which offered 75 HP in stock condition. But thanks to some performance upgrades, this engine produced 5 HP more than the one in the Xi Sport.
The key features of the Kawasaki Xi Sport engine were as follows:
- 2-stroke, 2-cylinder architecture
- Dual Keihin CDK 40-31 carburetors
- NGK BR8ES spark plugs
- Crankcase reed valve configuration
- Oil injection system
- Magneto CDI ignition system
- Open-loop cooling system
- Electric starter
- “Big-pin” configuration; ported for high-speed performance
It came with more durable engine internals and was ported for high speed rather than bottom-end power.
Engine power was delivered to an axial-flow, single-stage jet pump utilizing a 3-blade impeller. This high-performance jet pump produced a maximum thrust of 653 pounds, which was 25 pounds more than its predecessor.
The fuel consumption of the Kawasaki Xi Sport was 8.2 GPH at WOT, which ensured a cruising range of 51 miles or a riding time of 1 hour and 4 minutes.
