The 2017 STX-15F’s handling is sharper than its competitor’s offerings, and the power accentuates the feeling of the boat’s deep-V hull design, making the 15F seem far more like a racer. It dives in and out of corners with tenacity, never threatening to spin out from the load. For more serene rides, the bolstered saddle gives touring-oriented comfort, and stability is equally rock steady.


Theft prevention is accomplished via a magnetic key. A second key can dial back the engine’s performance to tone things down for true beginners or to save fuel. Storage, at 89 letres, is split between the bow, glovebox, and a smaller compartment under the saddle’s aft.

The 2017 Kawasaki Jet Ski STX-15F greatest appeal comes back down to power. It’s nothing to dismiss. A top speed that flirts with flagship model numbers, it will hold a great deal of appeal for those with performance leanings, as will the aggressive handling of the STX hull. That combination of power and handling are precisely why the STX-15F remains a leading competitor in its class.
