Concept motorcycle design is supposed to grab your attention and the Icare by Enzyme Design certainly does that. Looking more like a creation from a futuristic sci-fi movie or computer game, it is actually based on technology and engines already available.
Power comes from a flat six, either Honda 1800, or as one rendering shows, perhaps a Porsche. With all of the bodywork on this bike, you could hide all sorts of engine accessories like blowers, turbos or what have you, plus the suspension could be pretty exotic and it, too, would be well hidden. Of course, with this much bodywork you could hide almost any kind of powerplant, you're not confined to the old internal combustion engine by any means though it's interesting to see something this far out with a Honda 6.
The side skirts around the wheels seem to rotate up out of the way as does the bodywork which evidently has some type of parked mode which then moves into riding mode when you turn it on.
I rather doubt we'll see anything like this from any major manufacturer, at least not for the foreseeable future, but a technically proficient custom builder might pull it off. Interesting.
A tip of the hat to Brian for the pointer.
