V4 History
It began back in 1979 with the introduction of the NR500 grand prix racebike. Rather than fielding a 500cc two-stroke engine, Honda used a four-stroke oval-piston V-4 motor – essentially a V-8 with four cylinders that could be revved to 19,500 rpm! The oval cylinder area was so large that it used eight valves in each cylinder!
