Those are the ones they don't bother to dub, I guess. This one was on German public TV but they still managed to squeeze a graphic scene in with someone taking a dump on someone's lawn then...well, you don't want to know. Good movie otherwise, but I guess if it doesn't have boobs or poop, it's not really art. I would have preferred the boobs.
Anyway, that appears to be a 60s R60 with a Stieb sidecar, which is awesome in itself -- but the pig, that's just way awesome AFAIC.
