The very first production model TY250A made was stamped 434-000101, it was the first of approx 18500 "A" models to be built, #101 was kept by Yamaha for the factory museum..
The very first production model TY250A to be sold was stamped 434-000102. Here is a photo of #102 nearly 35 years after it rolled off the assembly line.. I found it in the mud in a salvage yard overseas about a year ago.. Its currently soaked in CRC but will be going to my restoration guy in a few weeks for the full treatment.. I will post photos when its finished if anyone is interested..

Re: TY250A. The very first one.
mate if thats all true, you have yourself a pretty good score there 
Re: TY250A. The very first one.
Oh its true alright, not the prettiest one Ive seen but the matching numbers are there for all to see, Ive been playin with TY's for longer than I care to remember, so after 30 years of lookin, I guess the odds are that I would find it one day
Even the Yamaha Museum have emailed me..
Re: TY250A. The very first one.
Just had a look at your 250B restoration photos, youve done a good job, I have the restored 250B currently on ebay.. I may be able to help you with some NOS B parts if you get stuck, I have the odd one floating around here..
Re: TY250A. The very first one.
Gday just jumped online to try and work out exactly which bike it is that i just purchased and it sounds like you may be the guy to ask, the frame / engine number is 434 011917 and i am guessing if i add 18500 to the origonal number you quoted 434 000101 then my bike would fit into the 250a bracket...?
Re: TY250A. The very first one.
Hi.. Yes yours is a TY250A model, its #11816 off the production line making it a 1974 model, if I can help with any other questions, just drop me a line back..
Re: TY250A. The very first one.
thanks dyan00! Its great to know what i am working with as i plan to retun it to a somwhat origonal state, and i can imagine as time goes on i will definately have some further questions for you! Cheers Ben!

Hi
I was just going through some old posts & noticed this one.
Have you got any shots of the finished bike as I would love to see them?
Cheers

Hi.. Warren, its hard to believe it was 4 years ago when I posted the pic of #102, its still sitting in my garage, I havent touched it since I posted the pic, I will have to get it up to my resto guy and get it done, I will keep you up to date with the progress.. thanks
