i have only ridden 3 bikes....an 04 crf80, 05 yz85, and 04 rm85....and to tell the truth my least favorite was the yz85 it wasway under powered on low end, had terribley suspension, and over all just sucked at least for what i look for in a bike. realy the crf80 is awsome as a play bike and just a bike to cruise aropund on real slow when you dont want to ride that noisy pinger. and i love my rm85 it is deffinetly th best bike iv ever had its got enough low endto get me goin and enough top end to be fast as hell, has good smooth power, and is just a great bike overall.
