How do you find out what year kawasaki motorcycle engine have by the numbers?

Identifying Motorcycle Numbers  Kawasaki engines, similar to many other engines on the market, usually comprise some variation of this format: "###cc####." Let's look at a hypothetical number such as, for example, 750N51434. In most examples that Kawasaki provides, 750 stands for the "cc," in this case meaning 750 cubic centimeters for engine size: N marks 1991; and P represents a motorcycle manufactured that year, meaning "ZXR 750.

If your year is after '999 (i.e., 2000, the 51 means “2005.” It goes 50 =2000; 51 = 2001, 52 stands for “2002,” while 82 means “2008”; 92, for example, stands for 2009; and in your provided VIN "85" means 2020.

A final set of four-digit numbers will accompany most of what has been described - these final characters indicate production numbers - i.e.: 4321 stands for "the 4,321st bike with these same exact engine specifications ever created.
