Hey guys, I'm not into dirt bikes to much, I love the quads.....but take this into consideration. Look at the weight difference, even if there is a HP difference, it would still be hard for me too see the shee coming out on top. I love my shee, but I don't go out looking to run a dirt bike, simply b/c its out of class not comparing apples to apples here. I guess it really depends on the operator and the distance, conditions of the run. Sounds like a good trial here, run 'em and post the results.
