2026 Kawasaki Jet Ski Lineup: Specs, Prices & Review

The 2026 Kawasaki Jet Ski lineup is here—and it represents the most significant update the brand has delivered in years. Kawasaki has refreshed three core families for 2026: the Ultra 310, the Ultra 160LX, and the all-new STX 160. Every model is powered by a proven 1,498cc Ninja-derived inline-four engine. Each model now adds modern cockpit displays, upgraded rider aids, and improved handling technology. Whether you want a supercharged flagship or a family-friendly three-seater, the 2026 Kawasaki Jet Ski lineup has a model built for your ride.

Kawasaki invented the Jet Ski category, and it remains the only brand that legally uses the trademarked “Jet Ski” name on personal watercraft. For 2026, however, the brand took its most aggressive product development stance in over a decade. Most notably, the all-new STX 160 platform is the biggest redesign in 20 years for that model. In addition, every 2026 Kawasaki Jet Ski runs the same Ninja supersport-derived 1,498cc inline-four engine. As a result, this shared platform targets both loyal Kawasaki owners and buyers cross-shopping Sea-Doo and Yamaha WaveRunner alternatives.

2026 Kawasaki Jet Ski: Engine & Technology Platform

All four 2026 Kawasaki Jet Ski models share a liquid-cooled 1,498cc inline-four engine, which is derived from the Kawasaki Ninja supersport motorcycle platform. Specifically, naturally aspirated versions produce 160 horsepower at 7,500 rpm. In contrast, the supercharged Ultra 310 adds an Eaton Twin Vortices Series (TVS) roots-type supercharger producing up to 16.8 psi boost. Furthermore, every 2026 model includes Kawasaki Smart Reverse with Deceleration (KSRD). In addition, higher trims add a 7-inch full-color TFT display with Bluetooth, selectable power modes, electric trim control, and Kawasaki Smart Steering for low-speed control.
