Cyclepedia features an online decoder for Yamaha motorcycle VINs. Visitors to Cyclepedia.com can enter a 17-digit VIN in the search field, and click the Decode VIN button. The program works for any motorcycle and returns the make, model and year for many motorcycles, ATVs and scooters.
Carfax.com and DMV.org also have VIN decoders. Typically found on the steering neck of a motorcycle, a vehicle identification number has 17 digits that are comprised of the world manufacturer identifier, vehicle descriptor section and vehicle identification section. The numbers remain with a vehicle throughout its operational lifetime and are used by service technicians to identify the transmission, engine and brake system.
