The way to decode a Honda motorcycle VIN is by the numbers and letters in the VIN. The first number is where the bike was made. The second is a letter usually an H and stands for Honda, the third denotes the type of vehicle. The fourth through eighth identify the engine type. This information can be found by going to Motorverse and inputting the VIN number of the bike in question.

That's most likely the frame serial # not the VIN #. While in some cases they are the same, the format was AAAN-NNNNNNN where A is a letter and N is a number.
That is not a correct VIN# so I cannot decode it.
You can decode the VIN number online. Find the VIN on your registration or stamped on the frame, usually right on the neck.
Honda has a tendency, just like most motorcycle manufacturers, to place the VIN in the area of the front forks, around where the forks "connect" to the body of the motorcycle.
