Thankfully, today we have an ever increasing interest in vintage motorcycles. Real motorcycles with Real Motors hanging out in the wind for all to see and enjoy from virtually all angles. A well crafted motorcycle motor is truly a thing of beauty. It is the centre of attention, the main act, with all the other parts being merely supporting players.
The following link is to a photo gallery of close up images of motors in some motorcycles that I photographed at vintage events in 2013.
