I just purchased this supposedly 1965 Ducati 250 something or other from the original owners widow. They bought it in 1965 brand new as a race bike. It has never been Registered or Titled. He died in 1976 of Mad Cow Disease, He was only 30. He had the bike painted and/or pinstriped in 1966. This is the original paint/pinstripe job from 1966. I am assuming the bike was a different color originally maybe... But there is no other color under this red color or other primers. I am no Ducati expert but it might be made of different bikes or was something, I just don't know. I know he was a serious racer. Just going off of the parts on this bike I see 4 different versions of ducatis and I don't know what I am looking for. Doesn't even have a front brake cable. Any ID help would be awesome. I haven't started the engine yet either, it turns over very nice and has a lot of compression. But there is no on/off switch either.

the frameloop over the top shock mounts indicates that this is a Scrambler frame . tank is also correct for a scrambler .

however a scrambler should have a 27 mm carb but could easy be swapped for a 29 mm carb

____ It's looking overall as a 250-Motocross but no-doubt is indeed a 1965-Scrambler (with 5-gears).
And thusly should have a 55t rear-sprocket and a 14t drive-sprocket with an internal chain-guard.
__ I've also owned a few of the very same model.
Does yours have a motor-number starting-with '91---' ?



" But there is no on/off switch either. "

____ All such pre-66 off-road models came-stock without any key-switch or kill-button ! _ Ya turn-off the petcocks (ahead of time) and then fully whack-open the throttle while at idle or dump the clutch at a stop, to stop the engine.


____ Check the oil, put some fresh gas in the carb,, then slowly rotate the kick-lever until the compression is almost all bled-away, reposition the lever to best leverage, and then give it a hard kick-through, to attempt engine start-up.


Hopeful- Cheers,

Yes the engine number is DM250 91609

Ultra-cool Ducati 'dirt tracker'. Congratulations on a spectacular find.

Front brake cable no doubt removed for dirt track racing, where no front brakes are allowed.

Before starting, you might want to remove the valve covers, right-side cam cover and spark plug, shoot some oil on the cams, valve stems and cam gears and into the cylinder, then turn the engine over a few times to get everything lubed up.

Rig up some lights for the ultimate lightweight 'street tracker'!

Awsome bike! I wouldn't change a thing! other then possibly the header pipe if you plan on starting it around living people.
seriously, I hope you realize what an awsome period Ducati you have there and keep it as such, IMHO

Its going to be kept inside of my house like it has been for the past 38 plus years. I don't plan on changing a thing. This bike deserves to be kept in this original condition, except i want to get it running. I also don't like the home made vinyl handyman wrapped seat cover someone made. I think a custom made light brown leather seat with Ducati tooled into the back would really make this bike pop.

Here are the tire combos
The rear is the Dunlop 4.0 x 19
The front is Pirelli 3.25 x 19
These tires are over 40 years old.

I'll have to take some better shots but this is what I have right now.

Heres a few questions I have.
