How can i tell the age of my RM125 - 2003 Suzuki RM 125

I forgot to mention. If you're a paranoid type about posting the VIN, just change the last 5 digits to XXXXX so no one knows the bike ID. If it's a 1981 or newer, the VIN will start with JS1RF. Just make sure you have the string like this posted: JS1RF14A_L21XXXXX (The X's are in place of the actual bike ID number for security purposes. The "L" in the above string denotes the year. In this case, the L stands for 1990).

If it's a 1980 or older, your VIN will start with RM125, followed by some other numbers. They did not use alpha characters in the VIN to denote the year. I have this cross reference chart too.
