This is Kawasaki’s flagship model with a supercharged 310hp engine. As an ex-demonstrator with minimal hours, it’s essentially new but priced significantly below retail. The 310LX features a supercharged and intercooled 1,498cc engine that produces serious power – 310 horsepower to be exact. The deep-V hull handles rough water well, and the luxury seat adjusts to three positions for different riders or riding styles. Storage is generous at 44.5 gallons, plus there’s an 80-litre fuel tank for extended range. The electronic throttle system provides precise control, and if you opt for it, the JETSOUND audio system is a nice touch for more relaxed cruising. At 3.6 meters long and weighing 483kg, it’s a substantial machine that feels solid and stable. The semi-dry sump lubrication and water cooling systems are designed for reliability, and electric start means no faffing about with pull cords. This particular unit has been used for demonstrations only, so it’s had only 5 hours use. The full manufacturer warranty transfers to you, which provides good coverage for the major components.
