I'm considering buying said bike. Are there any things specific to this model that I should pay more attention to before buying?

Nothing really & were a top bike back then. Mind you in close to 50 years a lot can happen. If i remember right the alternator has brushes not that they were prone to wearing out prematurely. Can only go by looks & sound & ask for any history of mechanical work the owner might have or know of.

Well turned out it's a 1975 in very sad shape. Only thing keeping me from pulling the trigger is the price. Are these bikes very sought after???? Only real positive is it has a title :unsure:

I had a 73 forty something years ago . They are good bikes , but the 250 is far less
sought after than a 350 . If it's not in great condition , it could wind up being
a money pit .

I have a '73 RD250. They are a really fun bike if they are in decent shape. You don't indicate much about the condition or price, and as indicated a man can spend far more to 'fix it up' than they are worth, or that one could sell for. Actually, that can be said for virtually any of the old bikes we play with! :lol:

Pros: easy to work on, most parts readily available, apart from NOS tin. Good source for parts/service is HVC Cycle ( hvccycle.net/ )

The '75 has the disc front brake, earlier ones have the DLS drum (which is still pretty good, and you don't have to bleed it, just change the darn shoes if they are original). Should be white with red striping. Usual caveats apply- avoid something that was obviously raced, or heavily modified. Chambers and pod/open filters may make it go a bit faster, for a time (:ROFLOL ). Pretty easy to make it a 350 also, bore size mostly (although the oil pump part numbers are actually different, I do not know exactly what that difference is).

Out of curiosity, what is the asking price?

Last point: It is sometimes more fun to make a slow bike go fast, than make a fast bike go slow, at least in the real world!

Yes 350 top end bits all swap over so an easy upgrade [& leave 250 stickers on lol].

Yes, top ends swap... 250's are nice the way they are though.

Primary gear ratio (crank and clutch gears) are different on the 250 which is one reason the oil pump is different.

Yes, most are identified with a model code stamping on the front of the choke (technically "starter lever") boss or sometimes on the side of the carb on a little flat area.

Early flange mount carbs usually have the stamp on the top edge of the flange.
