The Kawasaki KX 250 is a popular dirt bike. Since 1981, Federal Law has mandated all vehicles (including motorcycles and dirt bikes) follow the same 17-digit VIN formula. This formula allows you to easily break down the VIN and find out more information about your KX 250. It also allows you to determine what year model your KX 250 is.
Find the VIN on your KX 250. The VIN (vehicle identification number) is stamped on a plate on the steering tube leading up to the handlebars.
Count out the 10th digit and write it down. The 10th digit signifies the year model of the KX 250. See "Tips" below to learn the year model each letter or number signifies.
Go to the Kawasaki website (see "Resources," below) and let the system decode the VIN if you have trouble determining it on your own.
Pre-2001 VINs used a letter to specify the year. The letter "Y" was used to specify 2000 models, "X" was used to specify 1999 models and "W" was used for 1998 models. Each step backwards in alphabetical order refers to one year model decrease. Beginning in 2001, numbers were used instead. The number "1" specifies a 2001 model and "2" a 2002 model. The numbers ascend with each year model until the 2010 year model, when the alphabet will start from the beginning with "A."
