im really thinking about getting a 450 . Most likely it will be used but maybe new. But i would like to know if it would be a good buy or not?... i no stock from the dirt wheels mag, it tops out at 76, which is great, but the thing I LOVE ABOUT it is that it HAS REVERSE! This makes it great for me bc i do a lot of trail riding and little track with my friends.... but what i wanted to know if this is a good 450 to but???...
