125 Sport frame

Postby WayneO57 » Mon Dec 21, 2015 11:38 am

Hi Scrubs
I have a question for the historians of the forum.
I am trying to find out when the 125 frame changed from a pressed metal "welded" front tube to the standard tube.
I have seen the similar frame as mine on the 100 sport, the 1956 Gran Premio.
I have seen a frame DM200###DM noted as 125 Sport 1st series, My frame is DM201228DM & it has the same front tube.

SO ALL YOU HISTORIANS please help

I've only seen the front down tube made by welding pressed halves together used on 1957 production models. The only verified 1958 model I've seen had a round front tube, and I've never seen a photo of a factory race bike with the welded front tube.

Thanks Rick
I wasn't sure,
Looking at pics from the Ducati website showed the 100 with the frame
I found pics of a similar frame on a 1958 175SS F3 replica

Starting to do my head in, there is so little information I can find on pre 1960 bevel drives

check the slide show here for 1956!! 125. it is the Ducati website so it must be right
