i am excited about all the other 450 class machines coming out. ktm will have their top of the line mx quad out but they will also be releasing a xc version of it first. and polaris may put a 450 race machine in it. i think all this competition will make the manufacturers work as hard as they can to make theirs the best. its a winning situation for us.
edit: i also noticed that the ds might have a left side exit exhaust?
