The once clear delineation between the car and motorcycle has become somewhat muddied in recent times with the emergence of an array of narrow tracked vehicle designs sporting two, three and four wheels. Kawasaki threw another fascinating oddity into the ring at the Tokyo Motor Show today with the unveiling of the outlandish, shape-shifting "J" 3-wheel electric vehicle concept.

Looking something like a Tron Lightcycle in Kawasaki Lime Green livery, the J is able to morph between a low-slung riding position (Sport Mode) that allows the rider to carve through corners at speed and a higher stance (Comfort Mode) in which the distance between the front wheels is widened for more relaxed urban cruising. Steering-wise, the J has neither a wheel or handlebars, instead employing two levers that seem akin to those found on zero-turn ride-on lawn mowers.

Details of the all-electric vehicle's drive-train are scant, but Kawasaki says the J concept makes use of its proprietary battery management technology and GIGACELL high-capacity nickel-metal hydride battery.

We would love to throw a leg over one of these beasts, but at this stage there's no indication that the J is likely to move beyond concept stage.

So what's your verdict? Outlandish, outstanding, or a bit of both. Let us know in the comments below.
