Bought at a garage sale off the widow of the original owner. Bike cost $100, title transfer $130!!!
I read about these when I was young and always thought they were interesting. The engine works with an overhead "face cam", a spinning pie-plate with bumps on it to actuate the rocker-arms and valves. Not a common engine design at all, I think besides Capriolo there was a British engine sold in the 1920s that had a similar valve mechanism.

I did not see much on the Capriolo with a search of this forum so I thought I would add this one. I think the Caproni company made very few motorcycles from WWII through the 1950s then closed. An importer in the USA bought most of the factories unsold bikes, parts and anything else that was not nailed down and sold about 1200 left-over bikes into the early 1960s, marketing them as whatever year they were sold. Similar bikes in 75cc, 100cc and 125cc were made, but strangely the engines although looking very similar did not have a lot of interchangeable parts. The usual practice would be to just alter the bore/strokes of one set of castings, but Caproni seems to have made a large number of different castings and parts each of the three engine sizes, so they must have been terribly expensive to get into production, and not very profitable.

Always fascinated by oddball internal combustion engines, when this one popped up locally I had to check it out.
