A belt primary drive transfers power from the rotary's eccentric shaft (the Wankel's "crankshaft") to the separate Yamaha OW01 six-speed transmission. Although difficult to distinguish in this photo, the actual rotary engine is very compact, with an overall size not that much larger than the oversize ignition rotor. Note the oil-injection pump (the rotary is like a two-stroke in that its combustion components are lubricated by oil in the intake charge) driven off the clutch shaft.
