The cafe racer

In the sixties' British counterculture of 'ton-up boys', a specific type of motorbike evolved, one with which they could speed between transport cafes along the newly built arterial motorways. The goal was to be able to reach 100 miles/hour ("ton") along a route where the rider would leave from a Cafe and race to a predetermined point and back before a single song could play on the jukebox.
Getting more serious about a bike purchase, here's a truly great one. It's far more of 'real' bike than the BMW. This one's a '57 Norton Featherbed frame and a Triumph Bonneville 650cc engine. Not many were exactly the same. In watches we call it frankening.. mixing and matching parts. This was about the first time this happened in the bike world. Choppers were the US version of customizing.
