Well from that list I see some anomolies. I've never seen a bike built in '87 with an MSO as an '86 model. As I understand it the bikes built as '86 models (9/85 build date)
Paul -
I'm a little confused. I thought the change-over for model years happened after the August "vacation". Thus a bike built in September 1985 would be a 1986 model. That's the case with my September 1977 built '78 R100/7. So then, why isn't a bike built in July or August 1987 not called a 1986 model???
