I kinda confused on what to buy , first of all I want to stay with yamaha motor company because I 've had such good luck with them in the past. I not going to be doing any racing track wise. just ridding the fields and woods around my house here. so in that case the raptor would sound like a better investment with reverse and all , but then again I want to build a stong running four wheeler that can't be touched around here. I am planning to put nitrous on it for that last min supprize , if someone starts burning my ass in a drag race. it wont be used very often , but its there if I need it kinda thing. I'm not that lazy that I cant get off and pust it backwards if I need to so reverse isnt a big issue. but as far as after market parts witch one can you get more for and all . I'm no dummy to the atv world , I keep up with the info if a new one comes out and all. I talk to the owner of a nearby yamaha store . and asked him what he thought , he said the 450 was over priced and pretty much said ya get more bang for your buck with the raptor , meaning reverse. to make a long story short for my purpose witch is the better buy .
