Its going on 2 months now since I crashed my 636, and its time for me to get another bike My 636 was a 03 with a power commander and a yoshi slip on. I absolutely loved the bike! It was great other than riding kinda bad I have NO complaints. Im kinda on a limited budget so i've been looking on CL and ebay for another 1. I found an 07 600 thats in my $$ range. Just curious what the major differences between the too would be? I can only believe everthing would have made major improvements in 4 years? Just wanted everyones opinion b4 I go 60 miles to check the bike out.
