GT Serial number decoding

well we get a good bit of gt serials that could be identified by the owner, if they only had the tips that some of us have learned, so i will post what i know, and anyone with more knowledge can add to it..so here we go.


here is an example to go by. on the dropout you have "M1" followed by "08922198"..this one is simple.

M1 stands for "mach one" that is your model gt. it can also be a "I" for interceptor and so on.

next on the serial is "0892" this is easy to decode too, 08 means 8th month, which would be august.

then you have "92" next in the lineup, this would be 1992

the last 4 digits, are your build number, this one would be the 2,198th one built.



Here is another example. if your serial is KGCG2297 this one gets a little complicated. but still easy once you learn the code to it.


the first letter is who made the frame itself, in this case it would be "Kenisis", an overseas company.this could be replaced by another letter but at least we know what that one is there for.

next is the letter "G"..this isnt always there, but if so, this is where it was assembled, (ever notice the built in usa sticker on your gt or dyno?) this is what that letter is there for. it wasnt made here, but was built here.

next is the letter "C"..C is the 3rd letter in the alphabet, and march is the 3rd month, so march is the build month.

next is the letter "G" this is the year. G is the 7th letter in the alphabet, so this would be a 1987.


here is one more..your serial resembles this:f6030578.

to start, if you have a "baseball" looking stamp behind your serial, this frame was made overseas...no its not a pacific, so dont cry, or get mad...and lets continue.

on this serial, the first number is the last digit of the year, so 6 stands for 1986

next is "03"....this is the third month..which is march.

so you have a gt built in march of 1986.

but still use the museum as a guide to id the frame, cause sometimes you can find the year, but getting a posotive id on the model isnt possible without knowing which style frame you have.

this doesnt apply to new gt's, but hopefully some people with info on those will chime in. this isnt always going to match your serial, you may have a "fake"..its not likely but it happens. also on earlier models this can differ. this is for the 2 most popular style serial's i see on here. also, common sense tells you that if you have a suspected "gt" frame, look it up and compare it in the musuem, knowing which style frame you have will help with the process of id'ing your bike with the serial, especially if the serial has some damage that prevents you from getting the full number.

hopefully this bit of info can be used for everyone, and this will save you from those late nights sitting around waiting for a response to your post looking for an answer to the idendity to your gt...although i do feel smart and proud when i can answer these posts. well, thats it for me, if anyone else has info on serials or if you see a mistake in this guide, tell me so i can edit it. happy holidays people. oh and thanks gary for the "gt serial number explained" article in the museum, that taught me a lot and is a great peice.

Re: GT Serial number decoding

My serial number isn't exactly working with the aforementioned description...

Please help.  I've got a GT Performer that's definitely either a 1991 or 1992 (I know this, because I am the original owner). 

The serial number is:  GH91060916 (or GH91860916) ... the peg on the rear wheel was on so tight that it made it really difficult to decipher the 5th digit.

It's possible the the GH is the location, and the month and year have been reversed, e.g. 9106 meaning June 1991.  It's just a guess, but I'd really appreciate others' thoughts.

(I'm trying to post photos, but the server keeps resetting.)

Re: GT Serial number decoding

Anyway to tighten this up and put it ina spreadsheet format so it is easily readable? I think something like this would be nice to carry around in a bike hunting reference journal of sorts. You know, something you can keep in your truck while you are out and about hunting bikes. If you don't remember what is what then you can refer to it instantly.


I get this question often so here it is to save everyone time. I do not have any Mongoose DMC decals left. I was lucky enough to find a small bunch of NOS decal sets in an old bike shop that no longer exists and I have since sold them all. Sorry. I wish you all the best of luck with your DMC builds.

Re: GT Serial number decoding

Re: GT Serial number decoding

ya that is probably right - I was thinking 85 but I don't remember it's all a blur now -  coulda been - it was oold school. It was baby blue with red trimmings, red tuffs and what not. It went thru hell and got passed around between all my friends like a cheap lady - we all rode the hell out of it over the last 20 years.
It's in Germany now gettin rode some more smile
