Found this video on Red Bull.  This is really cool.

Gee Atherton, DH world cup champion

vs.

David Knight, World Enduro and GNCC champion

It is amazing to watch the line selections that the 2 vehicles have to choose.  The motorcycle has more pace in the fast sections, but cannot flow the turns as well as the DH bike.  The DH bike seems to be able to hit the slow technical spots with more pace than the motorcycle.  A DH bike can go better on downhills than a motorcycle.  It is purpose built, and can be pointed down easier.

Still, Gee’s lines through the rock field towards the end is impressive.

I could not get the video to embed in the post, so you will have to link out to it.  It is worth it though.
