Hello,
I am looking for some help in identifying this motorcycle. It is an ex-racer from Idaho, USA, apparently. Sold new in USA.
The Frame Number is 110967.
The engine number is 114935.
I have had a look at Bevel Heaven at numbers etc but a little confused.
Curious about the red frame - maybe it has been repainted to make it look like a Super Corsa?
Sorry I don't have any better photo's at this time.
Any help would be appreciated.
Thanks

Dont think that is a desmo, looks like a normal 350 widecase - Tom Bailey states in his book on Ducati singles that all of the records from the 60's singles were destroyed by cagiva in the mid 80's so the numbers are not a big help. Could be anything including a scrambler. looks to me like a typical AHRMA racer made from a nothing special ducati single.

Would it be possible to whip off one of the valve covers and check if it's a desmo?

A desmo head would add few dollars to the value but it really wouldn't change much in terms of it being a special or rare bike. I would lean heavily toward guessing it is not a desmo, people don't generally put standard cam covers on their desmo engines - it just wouldn't feed the ego enough... :wink2:

it is a valve spring engine . the camcover is springer for sure . if you put a springer cap on a Desmo the rockerarmpins of the closing rockers would not be covered by the cap and would leak like a siff .
frontbrake is from a Suzuki waterbuffelo . no Ducati single ever left the factory witha Mikuni carb .
someone converted this bike to a racer .

I didnt know that the cam covers were not interchangeable - explains why I've never seen a desmo with a standard cam cover :wink2: The other stuff was pretty obvious...
And Ross888 - in case you ever come back and take a look here. All of the widecase singles used the same frame so there's no way to accurately identify what the bike was originally. The widecase road bikes didnt sell well in the states so the numbers are low compared to the scramblers which continued to sell well into the early 70's.

frame is a scrambler frame with the top shock mount more forewards .
the rear swingarm has the re inforcement strip under it like the scramblers and Jupiters had .

Thank you to all that have posted. A lot of good information. Any thoughts on the front forks? Are they from Suzuki as well? The rims are Takasago? The tank is not from a Scrambler?
Really appreciate the comments. Thank you.
If only some of these bikes could talk.....

From what I can see from the pictures, the forks look like standard Ducati Marzocchis and the tank looks like it's off an early Ducati roadster (Mach 1?, Mach 3? Monza?) Eldert will hopefully chime in with a definitive answer.

Martin is correct . forks are Marzocchi and the tank look like a narrowcase item .
i had a better look at the engine and it could very wel be a Spanish Mototrans engine .

How do you tell the Mototrans engines apart from the Bologna ones? It would explain the engine number as Ian Falloon states in his book on singles that they started from 114001 around '73. Thanks again for the comments.

Best way? Barcelona engine numbers start MD (= "Mototrans Ducati"), Bologna bikes DM (= "Ducati Meccanica").

the MD prefix was only used on the narrowcase engines . widecase engines have DM prefix same as Italian engines
the Mototrans head casting differs a little from the Italian ones the finning that is standing up at the exhaust port below the rockerbox cover is about 3 mm taller and the fin that goes from the intake manifold to the rear oildrain banjobolt sticks out more .

True - thanks for the correction, Eldert :smile2:. (Only the frame numbers still used MD ...)
To make amends, here's a photo that may help illustrate Eldert's words:
