The 2025 Kawasaki JET SKI ULTRA 310X combines high-output acceleration with the comfort, storage and stability needed for longer days on the water. Its deep-V hull, spacious three-person layout and sophisticated electronic controls give this flagship personal watercraft a versatile character suited to spirited solo riding, touring and recreational use.
At the heart of the ULTRA 310X is Kawasaki’s supercharged and intercooled 1,498 cc inline four-cylinder marine engine. The responsive four-stroke powertrain is paired with selectable power modes, allowing the rider to tailor performance to different experience levels and riding conditions.
Kawasaki Launch Control Mode helps manage trim during hard acceleration, while Kawasaki Smart Reverse with Deceleration adds intuitive low-speed manoeuvring and controlled deceleration. The ULTRA hull is engineered to deliver composed handling in rougher water without sacrificing agility.
A broad, tiered seat accommodates up to three riders, while the generous deck layout provides room to move comfortably. Adjustable electronic trim lets the rider fine-tune the craft’s attitude, and cruise control can reduce effort during longer, steady-speed runs.
The ULTRA 310X is designed for riders who want serious supercharged performance without giving up practical touring features. Its stable platform, substantial storage and rider-focused electronics make it equally capable of quick recreational outings and extended adventures across larger bodies of water.

ERGO-FITProper fit is key for rider comfort and control. However, the ideal fit varies from rider to rider, depending on their physical dimensions and riding style. ERGO-FIT is an interface system designed to allow riders to find their ideal riding position. Various points of the chassis interface (the handlebar, footpegs and seat, etc.) can be adjusted through a combination of interchangeable parts and parts with adjustable positions. This enables a wide range of riders to find a riding position that offers both comfort and control. Feeling at one with their machine, they will be able to experience how Kawasaki machines are fun and rewarding to ride. *Adjustable parts and their range of adjustability vary by model. |
