Hi, I'm looking at a 2006 alloy frame wr450f has around 3500 miles on the clock it's been used for light green laning and the odd enduro race. What are the main issue to look for with this year and bike? I currently have a drz with 440 kit, stage 1 cams and a fcr would I notice the difference in bikes or roughly the same? How would the bike hold up being used everyday for a 30 mile ride? One last question the bike has enduro wheels I'd be looking at putting it into supermoto trim. Would I need a cush drive or would I be fine with a standard hub? Thanks in advance and sorry if the questions have already been asked.
