This is just from memory, so the years may be off a little, but the small block was developed in the late 70s and first appeared in the US as a 500cc machine in 79 or 80. It was updated to a 650 a few years later as the V65SP. A modern version with FI was released around 2004 as the 750 Breva (standard) and 750 Nevada (cruiser). The modern V7 Classic or Cafe is basically a 750 Breva with different bodywork. All the small blocks share many driveline components with the major differences being displacement or cosmetics (tank, seat, pegs, etc.)
