1969 BSA Lightning 650 A7, Classic cool. The BSA Lightning invented it, this one personifies it. The 654cc OHV Parallel Twin, system engine design with twin carburetors and 4 speed gearbox that made 53 hp at 7,000 rpm was enough to move the Lightning to a leading speed of 115 mph even at 421 lbs dry weight. This one, it has pedigree.
