I have a friend who seems to think that the bike that was sold to me from a dealer as a 2002 is actually a 2001. I have checked the VIN with a lookup service like carfax and it shows as a 2002. He works at a bike shop and said that the 2002 426's have the new rounded rear fender, my bike has the squared off fender. Who do you think is correct? And are there any other signs to look for to differentiate a 2002 bike from a 2001?
