Here's a sketch from a Classic Motorcycle Show. Although there were some very old and rare bikes here, I chose some from the early 80's. These three bikes all have 'Turbo' decals at least once on the outside. Of course, this is short for the Turbocharged engines that they had. This term is a bit spoiled to me and seems slightly kitsch now. Back in the 80's, there were so many things that were said to be 'Turbo'. Bicycles, Gobots, washing machines and pretty much any other home appliance at the time.
I also liked how one of the bikes had Turbo written in reverse on the front... as if someone has good enough eyesight to look in their rear-view mirror and can read that while driving.
