Michael Terry Posted October 27, 2023 Share Posted October 27, 2023 (edited) I have 2 Yamaha motor cycles and have a question regarding 9 digit VIN numbers on my bikes. Can anyone help decode them, please. 1KT xxxxxx 1WGO xxxxx Any help would be appreciated as the DVLA seem to have made a mess of the V5s - one is down as being manufactured in Thailand! Many thanks Michael Edited October 30, 2023 by Snakebite68 Removing Personal Information... 1 Quote Link to comment Share on other sites More sharing options...
Moderator Snakebite68 Posted October 27, 2023 Moderator Share Posted October 27, 2023 I can't help, but I'm sure someone will be along who has a clue before very long... On closer inspection... If you scroll all the way down to the bottom of the main page, there's a link for a decoder.

NE0 Posted October 27, 2023 Share Posted October 27, 2023 (edited) The 1KT series is a TZR 250 from 1986. (according to wiki it states:- The parallel twin 2MA variant being the UK variant and the 1KT model being the domestic Japanese model. The 1WG series is a FZR400 late 80s early 90s. I wonder if the O in 1WGO is in fact a zero for the rest of the numbers ie. 1WG 01234. Also, if you're unsure, just type in : "Yamaha 1WG" or "Yamaha 1KT" into ebay to see the thousands of parts available for each of the designations.

Michael Terry Posted October 29, 2023 Author Share Posted October 29, 2023 Many thanks for your help. I have tried the VIN decoder but as both of my bikes only have nine digit codes, they do not appear to comply. Both are in the Marlborough colours and I think they may be special editions. I also think that the TZR 250 may be a very early model. I will keep searching! Quote Link to comment Share on other sites More sharing options...
NE0 Posted October 29, 2023 Share Posted October 29, 2023 (edited) Generally, (before they introduced the modern VIN ) all the earlier vehicles (ALL makes of vehicles) the number following the designation matches the engine number and it's quite simply the number off the production line starting at 1 etc. Both my late 70's bikes are alll designation codes followed by production number. and looking at Snakes post the decoder mentioned at the bottom of the page confirms the designation letters. http://www.johnnystoybox.com/parts_cross-ref_3.htm pages 14 and 15 as regards to the remaining numbers and looking at that decoder (The 9 Digit Vin part, yours are 9 digit ones) in more detail I'm not fully convinced, although it states the 5th number or letter is the YEAR and the 6th being the FACTORY code , ok fair enough ............but then it spoils it by stating the last three numbers are the production numbers, that would imply they only make a maximum of 999 machines!

NE0 Posted October 29, 2023 Share Posted October 29, 2023 (edited) Incidentally, it might not be wise to display your VIN in case some unscrupulous scrote decides to use it to clone another vehicle, given that there are bike thefts galore going on around the world!!! Just edit your VIN to be 1KT XXXXXX ( x= numbers) I appreciate they could randomally put any numbers that just happen to match, but yours are legite numbers registerd with DVLA. Just trying to protect you bud. Edited October 29, 2023 by NE0 1 Quote Link to comment Share on other sites More sharing options...
