Monza: Tipo del Veicoeo

[double diamond]

Everything you describe is consistent with an early 4-speed Diana. That top end should give a good result for your M1 replica. Don't scrap the remains of the Diana, still has some residual value. MW

Here are some pics from what I believe is a 1961 250 Diana. I don't put much faith in the foil tags, but this one is stamped D250 and the bike does have the butted spoks and M Baruzzo rims. It's apart now, as I am debating (with myself) what to do on the paint. The other aspect that points to the DIana is the seat - which are really hard to find.

" then the chassis is probably a Diana. "

____ One-thing I always feel somewhat obliged to do is try to help keep things straight which are otherwise passed-on as common-misinformation on old DUCATI-folklore.
After reading the past few posts, the otherwise clear-line between the old 'Diana 250' & the narrow-case '250 Diana Mark III' seem somewhat a bit blurred-up...
This has come to be a common-issue because so many 'Ducati-bikers' (DUKE-Duker want-a-be types) continually-insist on referring to the 250Mark-3 as a "Diana", which leads to confusion between the Mk3 & the REAL 'Diana' !
So whenever someone simply states "Diana", they really ought to be referring only to just the original 'Diana 250', because that model is a completely different Duke-model than the 'Diana Mark III' !
The sticker-tags properly reflect these often confused Duke-names, so most of us shouldn't have much trouble adapting to the proper use of them.
To avoid the resulting confusion, I-myself have always avoided using the name 'Diana' whenever referring to a Mark-3 model.
But too many others continue-on simply saying "Diana" instead of 'Mark 3' (when they actually mean to refer to a 'Diana Mark III'), so I keep having to make this distinction-point of mine (whenever others simply state: "Diana").


" Your engine has 1966 valve covers "

____I'm pretty-sure that the newer type v.covers (with the c.r.design), were first produced by late 1964, and became commonly stock on most all 1965-models.


" The Diana had certain parts in the motor that distinguished this specification (though they were quite similar to the scrambler at this stage) "

____ That's an example of what I had meant.
That statement is quite true of a n-c Mark-3 model but, the original 'Diana' motor was pretty-much the same as a Monza's motor.
