November 30, 2007 Design students from Colorado have come up with a mountainbike that incorporates a Kawasaki KX85 engine to bring a new dimension to the idea of lightweight motorcycle - around 125lbs, or just under 57 kilos.

There's not a great deal of detail on the machine known as “Project M85”, but the design was inspired by the fxbikes 50cc downhill MTB and sits somewhere in between a trials bike, a trail bike and a downhill mountainbike.
