Kawasaki Jet Ski Ultra 310x, When Kawasaki wanted to get a grip on the PWC industry, it knew it needed something special at the heart of the ship,
So Team Green turned to the world-renowned two-wheel division, borrowing engine architecture from the company Ninja ZX- Sports tourism 14R to present the Ultra 310R.
As well as getting a little extra displacement, the four-banger driving the 310R gets a high volume intercooler and a Roots Eaton Twin Vortices Series type supercharger which together allow the engine to produce class-leading 310hp.
All that power equates to 1,890 lbs of thrust, which can propel a 1,047.4 lb Jet Ski to a speed of just under 70mph. The 310R also features a competition-inspired look, from the angled fiberglass hull design to the “Kawasaki Green” and black racing patterns that adorn it.
There is also a Smart Learning Operation (or “SLO”) mode which limits power for beginner riders while studying.
