Just to dash that first thought of yours: Nope, not a concept. This is real, my friend.
The MonoTracer is an enclosed motorcycle or "cabin cycle," a style of vehicle which experiences a lot less drag than your average motorbike and keeps you from having to pick the bugs from between your teeth later. Its aerodynamic design and 130 horsepower engine get the MonoTracer from zero to 60 in about 5.7 seconds, and it has more speed than you'll ever need, topping out at 155 mph.
The MonoTracer is built by vehicle and engine construction company Peraves, and rolls off the factory floor starting at $82,350. Unless you're drooling gold right now, you may have to wait for Christmas for this one.
