Since posting this I"ve done some more research and according to my local Yamaha dealer here in Sydney my bike is a 1973 RD250, with a 1973 RD350 front end, hence the disc brake. It would have arrived here in Oz with a drum front brake. Much rather have the disc stopper

I"ve been told on good authority that the differance between the "A" and "B" models is the orientation of the rear footrests as can be seen in the 2 photo"s.



The more upright being the A model

To be honest there was almost nil difference between a US A and B, unlike europe who"s B had many changes. But the US B had sloping footrests with the paintwork of yours, so i guess yours is an A in B paint scheme or a B with the footrest brackets changed, but doubt it?



And no UK A"s or pre A"s had drum brakes, only UK R5"s and DS7"s had drum brakes.



There were a couple of models that never changed much if at all, the original RD250/350 to 250/350A was paint only so most refer to them all as A"s and the UK E & F, the F model is exactly the same bike a year later (apart from a nonsense tiny graphics change and the use of even cheaper electrical connectors here and there, but that was down to the fact the aircooled RD"s were finnished.

if your engine number starts with a 352- 3***** then this would be a 250b if it starts 352-2***** it would be an a and if it starts 352-1***** it would be a 250 simples this apply"s to us spec bikes never seen an american model with sloping rear footrests they are always upright

There was at least one, look at the brochure pic at the top!!!



But must admit my Italian 250 and I refuse to call it a B is white and the same as his with upright footrests, BUT it was registered very early 1975 which was pure UK A territory.



Johnny, when was the bike first registered, that will be a big help?



I also question the frame number designation which are mostly (or all?) unofficial

the frame and engine numbers tell you the model type and were it was destined, europe spec bikes start 352- 5***** for the 250 then 352-6***** for the 250a and then 522-0***** for the 250b there are some anomalys to this rule as some us spec bikes ended up being redirected to other areas  of our wonderfull planet and an odd  vin number turns up i had an italian regal blue 350b that had a 351- frame but a 521 -engine the last 6 numbers were the same on both i still have the engine not sure on your take of the vin numbers not being official you cant get more official than the vin number the data i have is official yamaha data from mitsui uk saved from the bin before they closed also pm me your vin and ill tell you what yours is

Looked into my log books and these white 250 and orange 350"s US and other country specs.



My Italian when new (And I didn"t think American style bikes went to Italy?), never been apart (until now)was sold to me many years ago as B which I just ignored and didn"t care! It is identical to Johnny"s with vertical footrests. BUT, after checking the log book it is a 74 M reg, not 75 with a 352-3***** frame/engine number, but was first registered 1974 and manufactured before this, the B as we know it was not released until way after that, approx a year later.



Unless mine has been UK registered incorrectly, but original Itilian paperwork seems to confirm it"s age.



It seems the white/orange US style bikes spanned 1.5-2 years without notable change (apart from sloping footrests and clock change)) 74 and 75 probably because they decided not to send the 521/522 B"s over there for some unknown reason, so they had two pre coffin paint schemes to our 3. Here is a link to a 1975 (B?) RD250 US bike with sloping footrests:

Johnny, another little difference on B"s is the updated speedo rev counter, easy to see on the speedo, the trip meter is at the top on B"s not the bottom as A"s, mine was at the bottom as A"s. Also what is your frame number?

the usa were allways the first to get new models getting there rd250 in 1972 they dont seem to worry about reg number changes like we did which changes in the august , sometimes why you get cross overs like 250c on a p plate. most launches happen in april the b model in the us although manufactured normally in the latter part of 74 is a 1975 model year as manufacture"s  work in model years not registration years , yours is defo a us spec 250 b do you have the italian log book?, who ever registered it in the uk may have declared it manufactured 1974 which would be correct , if you give me the whole number i can tell what month (pm) that it was made, and what country it was destined , im almost 100% that yours was redirected to italy or was brought in by a dealer or personal import, there was a shortage of bikes in europe and it was common practise to redirect machines from one  area to another if done by a dealer sometimes he would swap the paint over and a few other bits and bobs to make it legal in that country and make it look like a later model which adds to the confusion it may or may not matter to you, there are rd 250s here that were redirected from holland to make up the shortfall of bikes coming here
