Nothing can defined "cool" better than this monster motorcycle. The Hyanide is an all-terrain bike powered by a 60-hp 500cc liquid cooled engine but varies from other bikes in that it has a single track instead of the usual two tires. This means the Hyanide is able to move over many types of terrain including mud and snow with ease. What's more is that due to its extra wide track, it is highly stable especially at its top speed of 85 mph. Now sign me up for a test drive. Unfortunately, the Hyanide is not in production and there are no plans to do so. However, automotive enthusiates have expressed interest in the concept vehicle.
