The VIN information for various Suzuki 50cc scooters are listed below. This VIN info is difficult to obtain, and as you can see it's very preliminary at this point...

The 9th digit of the VIN is a check digit, and varies according to the production (serial) number at the end (last 7 digits) of the VIN.

The 10th digit of the VIN is the year code. The letters I, O, Q, U, Z are not used to avoid confusion with numbers::

1980 A  1981 B 1982 C  1983 D 1984 E  1985 F 1986 G  1987 H 1988 J  1989 K 1990 L  1991 M

1992 N  1993 P 1994 R  1995 S 1996 T  1997 V 1998 W  1999 X 2000 0  2001 1 2002 2  2003 3

Note that if your scooter was manufactured from say 2/86 - 2/87, it's likely to be a '87 model. This is fairly standard practice in the automobile and motorcycle industry.
