Sorry, bad example of the letter I. I, O and Q are never used in a Honda ATV VIN to avoid confusion in reading the number. If you see the digit 0 it represents a zero.
A well known source of VIN info is atvstyle.com. Unfortunately, the info is misleading. It shows a chart noting the World Manufacturer Identifier for ATV's made in USA and Japan. It leads one to believe the VIN number should start with the letters JH3 (Japan) or 478 (USA). Another page on this site shows Honda Model Codes. It includes ATV and Motorcycle codes. However, the list is incomplete and has not been updated. It does not include code for the TRX420 (TE40).
Dale, are you aware that your VIN number is different from other descriptions of your Rancher? For 2001:
TRX350FM1 Rancher S (four wheel drive, manual shift)
TRX350TE1 Rancher (two wheel drive, electric start)
TRX350TM1 Rancher S (two wheel drive, manual shift)
TRX350FE1 Rancher (four wheel drive, electric start)
TRxxxFA is a Rancher with automatic transmission. I’m not sure what year that first became available.
Perhaps the seller included some of these model identifiers.
The VIN number of my 2014 Rancher 420FM is:
Honda notes my Rancher as a TRX 420FM1E (F= 4x4, M= manual transmission, 1= no power steering; E =2014)
When I order parts my Rancher it is listed as a TRX420FM1 AC.
I get a headache when I talk about this stuff.
