Starting from the 1980s the motorcycles for the U.S. market received unique 17-characters VIN codes. Letters and numbers were used. The code is used to identify the bike and the manufacturer. The VIN decoder motorcycle is used to find out what each of the characters means and stands for. You can find the code on the frame of the vehicle, but the exact location can be different depending on the make and the model of the motorcycle you're interested in.

The first three characters identify the location of the assembly and the name of the company. The next figures and letters determine the trim, the type of the engine and fuel, the model and the make.

Manufacturers are allowed to use various combinations of symbols in the part of the code that is called VDS. This part is called descriptive. However, the ninth position of the code is devoted to the check digit that can inform the motorcycle VIN decoder about the validity of the code and whether it was somehow changed or not. The next characters define the plant and the serial number of the engine. The serial number can be also stamped on the case of the engine. You can find it on your own or ask the owner for assistance.

The VIN code cannot have O, Z and I letters as they can be easily confused with the numbers such as 0, 2 and 1 respectively. Every insurance company requires the VIN code of the motorcycle and uses the motorcycles VIN decoder to quickly find out the details about the engine and the components. You will use this data for searching for the parts for any kinds of repairs. Using original parts is a safe and secure way to prolong the life of the bike.
