I don´t personaly own the 05 cr 85 but I have riden it. I have the 03 model and to me it didn´t seem to be any different. I think Honda is puting there time and effort into the bigger racing bikes and the new 2 wheel drive enduro bike. I was asked to test the bike and it worked pretty well. There was no noticable changes to it accept a slight shape alter in the expansion chanber and obviously graphics. I looked hard to find anymore new changes but couldn´t.
