Inspired by their creation the Mobster, Blaž Šuštaršič of ER Motorcycles, Slovenia took a 1964 BMW R69S frame, strip it and put in a reworked BMW R80 RT engine then add in a few aesthetically pleasing design bits and bobs. The result is a modern looking café racer with a homage to its old genetic imprint.


What impressed me most are the rear suspensions; it is mounted in such a way that it creates an unfinished illusion.
