Forgive me if this message shows up twice, I seem to have lost the first message a few minutes ago.

When DKW made the RT 125 they used (invented?) Schnurle Loop Scavenging to make the engine more efficient. Apparently when Royal Enfield made their copy (model RE) they missed that feature and had an inferior engine. Did any of the so called "Hummers" use the Loop Scavenging design?
Just curious. I have been having fun looking into the history of motorcycle development recently.
