tm-enduro said:If you think that the Hbg 650 is not enough, then you have your work cut out. I would be looking at the TM660 (if you can find one). I have ridden the TM530mx and it is blazing fast, but the 660 will smoke it! TM only makes the 660 as a SM bike, but I suspect that TM would gladly build you a sand rocket.
Were talking 450s here, for a 650 I would need 130 mph. Are you a tard too?
