Hello. I'm just learning about the Bergs and I like what I hear. I love the look of the 2008 model, but I like the price of the earlier models like the 2004-2005. What would I need to do to bring a 2004 FE 450, say, up to 2008 FE 450 appearance. I assume the frame and subframe are the same? Can I bolt on all new front and rear fenders, side panels? Also, I notice the radiator shrouds are different. Do I need a 2008 gas tank to bolt the newer shrouds to? Thanks for your help.
