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...
