It’s been a long time coming but we have finally got our hands on a 2024 Kawasaki Ultra 310, Kawasaki’s supercharged performance flagship Jet Ski.

The latest generation Kawasaki Ultra 310 was unveiled in late 2021, arrived in showrooms in limited numbers in 2022 during the global pandemic, and then deliveries started to ramp up through 2023 and 2024.

When it was unveiled in late 2021, this was the first major redesign of the supercharged Kawasaki Ultra Jet Ski in 14 years.

The Kawasaki Ultra 310 is powered by Kawasaki's familiar supercharged 1.5-litre four-cylinder engine with 310hp.

Its main rivals are the Sea-Doo GTX 300 (supercharged 1630cc three-cylinder with 300hp) and the Yamaha FX SVHO (supercharged 1.8-litre four-cylinder with an estimated 280hp).

In this video we will cover Australian and US pricing, go through all the key features, tell you what it’s like to ride – and do acceleration and top speed tests using precision VBox timing equipment.
