look at the 10th digit of the vin number. tell us what it is and we'll tell you the year. Or, search for vin numbers in the search function here and you'll find the posts about what year bikes are. ;) It's tough to keep putting down all the years and the corresponding vin numbers. If you think it's around a 90-92, then the 10th digit should be as follows
89=K
90=L
91=M
92=N
93=P
This applies to U.S. versions of the motorcycles only and the Vin should be 17 digits long.
