If you look at other letters and figures, you can feel lost because you should spend some time on deciphering. The next letter identifies the name of the company, here we have Kawasaki and letter K. The letter J stands for Japan, the country where the engine and the frame were made. If you look at the code of your bike, you will see that the first characters are JK. The Kawasaki VIN number consists of 17 characters. Therefore, each of the vehicles that have been made after 1980 has a unique VIN number that is attached to the non-removable frame. Kawasaki bikes are produced in Japan for the US market.
