Default 1923 German engine for motorized bikes

hi guys,

just for fun (and a bit of history) since it's made out of pure un-obtanium, but here's some pics of a true gem: a 1923 four stroke clip-on engine made by Columbus-Horex Gnom, somewhere in Germany...

I find it impossibly cool

ciao!

well, it's got a normal sparkplug (in front of the valves) and a magneto, so it's a normal gas engine...

having exposed rockers arms and valves was a lot more common that you might think...

even the Ducati Cucciolo had them until about 1955 when they finally put a cover on them (but still no forced lubrication!!)
