Honda Part Numbers

From: barachj@connect.ab.ca

Here is a lesson on Honda part numbers: Almost all numbers are made up of three parts: five digits for the part (e.g., 13101 is a standard piston for all Hondas), three digits as a product code (e.g., 13101-300 is a standard piston for a CB750), and another three digits which indicate change ups or manufacturers, etc. (e.g., 13101-300-000). For body panels, etc. two letters are added for the color code. The only exception to this pattern are common items like nuts and bolts.

Since the product code (the 3 digits in the middle) are exclusive to specific units. You might want to know the product code for various SOHC bikes. Here they are:
