Frame is 450
Looks like a Scrambler as does the tank.
The engine looks smaller than a 450? What numbers are on the front of the engine?

What I've got is a frame stamped DGM7026-OM, DM450S*468248*; a tank, which I now believe is not original to frame; and as you can see, engine lower end without a head. I do think it's a good starting point.

Hi Roberto,

As per Graeme.

The "DGM7026-OM" part of the frame stamp is the homologation code for the 450 Scrambler frame. ("DGM" stands for "Direzione Generale per la Motorizzazione". This type approval was issued in 1969). The tank looks Scrambler, so probably does go with the frame.

The "DM450S*468248" part makes it a 1974. Its a late number, there being only three later ones on Robert Miller's list on Bevel Heaven (all listed as 1974): 468 295, 468 658 and 468 670.*

According to the list, the frame used to belong to a certain Brad Davidson and was paired with engine number 462321.

* My own bike, a 1972, is 465644.

Ciao

Thanks for the replies. I thought maybe the tank was wrong color, I read some where that 450s in 70s only had yellow tanks. I'll post number on engine later; the crank did turn free. What was the last year for this model.

I downloaded a figure, somewhere on a private italian DUCATI webpage, which listed the prodution numbers of all w/c Scrambler models. If have to check my harddisk, and if it reappears I will make an upload.
For now. The Scramblers appear lastly in 1975 - 250, 350 and 450 as well.

If this engine is 450,,,
The very last series had wider spaced bolts forward and rear of the cylinder opening in the cases.
The serial number for these was 46———— (I don’t know what number this case change started)
Also had the later ignition and alternator with two seperate cables exiting the case, 2 core and a 3 core.
From what I’ve seen in Australia these differences were all 1974 and later up to ‘75 in the scramblers.
Other countries may differ?
It’s hard to see in your pictures but it looks like your engine has the narrow bolt spacing from pre ‘74 but has 2 cables exiting the cases?

Either way you have a very good start to a bike that you will love to ride.

Ps I think the Scramlers in the US were called Jupiter and were yellow (450) but stopped before 1974?
Don’t know what country you are in?

You're absolutely right, Roberto. My apologies - I thought you meant that the tank wasn't correct for the model of bike. Which it is - and isn't ..

Because the paint scheme on your tank is from the very first wide-case 250-350 Scrambler from 1969! See below:

What was the last year for this model?

(To confirm what Hans said) 1975, according to Guida al Restauro ed al Manutenzione della Ducati Scrambler by Stefano Orio. See below.
Or 1974 according to Massimo Clarke in Ducati Scrambler, Desmo e Mark 3.

Also had the later ignition and alternator with two separate cables exiting the case, 2 core and a 3 core.

This is because these models were fitted with electronic ignition. This gets it kick via the 2 core wire.

Started in late 1972, if you believe the evidence of my bike. Or early 1973, if you believe Massimo Clarke in Ducati Scrambler, Desmo e Mark 3 ..

This is great info, amazing y'all can tell so much just from the photos.

Thanks

Can't wait to get more into this project. What are chances of locating a complete 450 motor.

[graeme]

I’ll guess you are in the US ?

Please tell me the engine serial number or just the first 3 numbers and if it is a 450. how many wires exit the cases above the left side.
If you are in the US you’re in the cheapest place to get parts.
What don’t you have (apart from head and cylinder)?

Does your book show the serial numbers for 450 scramblers in 1975?
