Even a John Deer farm tractor can be a beautiful machine... If it's in it's own realm.
Any purpose built design looks functional... the true beauty comes with using that machine to it's design potential! Trust me... when your hitting a set of 2ft high whoops at 40 mph or jumping a 60 double... A Dirt Bike is a very Pretty Machine!
The aesthetics of the COBRA are not what most people call pretty....but what a beautiful machine!
