I just picked up a clean 06 after coming off of an 05 and an 04. I cannot believe they can make such a different bike in just one year. This bike has increased my riding ability by about double. It will go up any hill I can find, just point, grab 3rd gear and pull the trigger. I should have broke down and sprung for a new one 2 years ago when they first came out, I've been missing out on a lot of fun.
