My buddy just bought one of these things and is well impressed with the power to weight ratio and the ride quality.  He has only had it a couple of days but said it reminds him alot of his old two stroke 400.  I always liked my 400, but didnt much care for the 500, seemed sluggish.  From what he told me I would really like this bike.  He still hasnt had it in any slop, so he couldnt tell me how it does there.  I know the 500's had a tendency to sink, but he thinks this one might have enough power to keep the momentum up.  Anybody of you guys got one of these?  If so have you had it in the goo to see what it does?  Not sure if I wanna shell out that kinda cash for a toy, but might if it is what I am looking for.
