I have been looking for a RMZ 450 for a while now and finally got one that I could buy for 8500 OTD, but I can get a KX450f for 7100 or a CRF450 for 7500 OTD. I ride all types of riding but mostly track, I race at tracks that are a tighter style motocross track, not a lot of straights and a lot of jumps with about a 1.5 min lap type track if that helps, I race open desert races every now and than. I ride dunes a lot too. I will be coming of a 2007 crf 450, which I loved the way it rode and handled. Handling is key for me because I feel that it is easier to adjust the way a motor acts than to adjust handling So with all this info what would you guys and gals do???
