My vote goes to the 2009 suzuki z400. I have one and have no complaints with it, the fuel injection is great. I ride alot of tighter trails and a few open trails and its great. Imo i would get as stated a 400 or a 700 over the 450. The 450s are nice but they perfer the track more then trails. The raptor 700 is very nice too. As dirt wheels mag stated in the shoot out (raptor 700 vs 09 z400), if you want to save $1500 and don't mind eating a tad bit of dust the 09 z400 is for you. Both are great atvs Imo.
