Monza: Tipo del Veicoeo

[Lonestar]

Hello all,

I'm closing in on completing my Mach 1 replica, a project begun in 2005 but sidetracked for a while. I have all the electrical components installed in the refinished headlight shell, but before attaching the headlight it seems wise to attach the new VIN plate I purchased.

This has 7 fields on it, and I've figured out most of them. Not sure what 'Tipo del Veicoeo' should be, though. As I understand it, a Mach 1 would be '250 M1', a Mark 3 '250 M3' and my SCR frame shows '250 D3'. But my bike began life as a 1966 Monza, and I'm not out to create a counterfeit Mach 1.

Can anyone with an original 250 Monza VIN sticker tell me what the correct Tipo is?

Thanks,

Dave

____ Ya might have figured that this sort of question has already been raised before, (I guess you didn't yet try doing any search here for such, or else you ought to have raised this matter from an established related thread)...
Here's a link to such a related thread : viewtopic.php?f=3&t=437&p=3085&hilit=Tipo+di+Veicolo#p3085
Anyhow, that particular wording would lead me to suspect that the 'TYPE OF VEHICLE' (such as 'motorcycle'), is what's expected to be stated in that field but, I THINK that (without actually looking at one of my-own Monza tags), that's where 'MONZA' would be stamped.
__ Better wait though, until someone who has actually looked at theirs, confirms so.

Bob,

Thanks, but I did see that thread and understand that the field means 'type of vehicle'.

What's uncertain is what Ducati considered to be the type of vehicle for a Monza in 1966. It doesn't seem to be a generic description, given that an SCR reads "250 D3" and not 'Scrambler' or 'motorcycle'.

Regards,

Dave

I seem to recall reading somewhere it's just plain "M" for the Monza, so would be 250 M. The 160 Junior was 160 MJ, the Sebring was 350 S, not sure why a scrambler would be D3...
I'm sure someone here will have one and can say for sure.

____ I believe wcorey is right, as "250 M" does seem familiar (as I recall seeing the Monza sticker-tag many times in the past).
__ So anyhow then, no-doubt you've -(Dave) also seen another thread where it was mentioned that Berliner (the US.importer) was suspected to have played-around somewhat with at least some of those frame-sticker/tags.
So there may be some inconsistency (if Ducati themselves ever did ANY of the tag-stamping on those original-stickers).

Every Monza VIN foil I've seen (including a couple I have in my possession) was marked "250 M" regardless of the year. 250 D3 is a Diana model type, not a scrambler. The early Dianas were marked "D 250", then "250 D3" for the later 4 speeds and probably the first five speeds, then "250 M3" for the bikes with M3 or M1 engine numbers. If your scrambler engine number matches the number on the frame tag but the chassis is obviously a scrambler, maybe it got a Diana motor installed at some point and the VIN tag was transferred as well?

DD,

Thanks for the info - just what I was looking for.

You made me curious about the SCR's VIN tag, so I investigated a bit. The engine number matches the foil tag (84414), but I believe it was never a Scrambler - I assumed it was because it was set up that way, but the frame has no rise in the rear loop. The Tipo is 250D3, and the date of manufacture 1963 (not the usual 196). So I'd guess it left the factory as a 1963 Diana and evolved into an off-road bike later. Here's a pic -

Good for you, now you have the option of restoring it as a real Diana.

Dave, Don't have much to work with there but certainly looks more like a Diana than anything else. I have a Diana frame with an 84XXX VIN tag, frame originally painted blue, same brackets and etc. as yours. Also looks like you have a 7 fin rear hub and maybe an M. Baruzzo rear rim since it looks pretty narrow. If the spokes are butted, and it has the Baruzzo rim, then the chassis is probably a Diana. Your engine has 1966 valve covers but, could have easily been changed. The Diana had certain parts in the motor that distinguished this specification (though they were quite similar to the scrambler at this stage) but what positively identifies it is the D3 in the VIN tag and an engine number that matches. That's also a pretty early engine number, so consistent with a 1963. Is the serial number stamped on the left case and DM250 on the right? If you look on this link: http://www.nealeandsons.com/Auctions/We ... ll%202.pdf and scroll down to the Ducati listings (they're in alphabetical order) there's a pic of an original 1963 Diana probably what yours left the factory looking like.

Well, that's an old picture - I bought it for parts to restore the '66 Monza I had bought earlier, which had engine damage. What you see is all there was of the bike, so it was a bit thin as a basis for restoration. I've since stripped it and the engine top end is in my Monza/Mach 1 replica, as it has the larger valves with shim adjustment. I thought that was because it was an SCR, but the Diana must have had them also. (Or it was modified, being a race bike - the auto advance was welded on full advance as well.) I also used the cam, which now looks to be a Diana version rather than SCR - should be fine, though.

Yes, serial number is on the right and number opposite:

Here's the current project bike; I installed the headlamp and front fender today:
