Wow its a super motard for the dunes.. I love it.
One question though, do you do much jumping?
Here in the Southern California dunes, I normaly jump into the BIG bowls.... And needles to say, I have tagged the frame on the ground more than I wish to admit (due to jumping at an angle (dune like a wall) and bottoming the bike (old suspension at the time).... It hurts.
Just the first thing to come to my mind when I see how low it is. Would be a Killer dune shreader though, and a blast in the nice twisty sections...
It must wheelie like a dream with that back tire... Im jellous..
