i think the best 85 is the suzuki rm85 and as a matter of fact my rm85 is for sale at the moment. if yopu would like to get in touch with me you can reach me by my email at mjwhaley@yahoo.com
There are many good 85's on the market. I would have to say theres a tie between the ktm 85sx and the suzuki rm85. The ktm is an all around good bike an you dont have to spend a lot of money on after market parts since the latest models come with vforce reeds and many other cool features, There is one down side to the ktm 85 though, its feels and im pretty sure is talle then the rm85 and is usually preferred by taller riders. The rm85 is also an all around good bike, it has a good stock suspension and a very good power band, plus the parts are easier to get then the ktms parts. The main difference would have o be the turning radius and the price. =)
