I have ridden the bike on long dune rides.  To be more of a specific duner I would shorten the swing arm.  Also need to soften up the suspension a bit.  Isn't going to go through the whoops like a rocket ship that is for sure.   Really comfortable to ride and the power is so smooth!  I actually rode it on a bunch of tight and twisty tree shoots.  Did fine, but just a little shorter would have made it perfect. 

That is my buddy's bike and it is a another conversion.  It has a Katana 1100 in it.  Bikes are very similar.  His was setup more as a drag bike in the video.   

I will say that my favorite part about that weekend was the two of us making pass after pass on bikes that we built.  I think we made atleast 15 passes back to back right here.  Too much fun!!!

I will ook and see if I have a few pics of his bike...
