In 1968 Yamaha Motor Company made the XS 650 Motorcycle. This Motorcycle is mid-size with one of the most advanced engines in its class. The engine and gearbox are unit construction with the crankcase split horizontally, which makes for easy assembly. All contemporaries in its class in 1968 were either unit construction, which had a vertical-split crankcase, or pre-unit construction with separate engine and gearbox.
