We are looking at a Pre-war Rennsport sidecar rig, built by BMW with the help of Steib sidecar company. If you see two of these in your life, consider yourself lucky.
Secondly, we can see a 1950’s Premier bike, only two known to exist in the world, that’s the one with the fairing.
Finally, next to Ozzie, is a 1939 R51S, another rare BMW.
