in order to get a bike registered over here we have to do an inspection at the technical control board called TÜV. those guys check if your bike is "safe for traffic". this can be very annoying, costly and time consuming and all bikers hate it.
if your bike is titled pre 1960 the whole process is way easier and you get the safety certificate without problems. all you need is a front brake, a fender and working and approved lights etc.
here's a neat little classic comic flick called that illustrates the whole thing. WERNER wants to get his sausage blinker registered..... enjoy!! hope it's funny for all you guys though it's in german
