Exploring Lightweight Materials On Motorcycles

As a technological demonstrator, the 1992 Honda NR750 was unmatched in its day and even still holds its tech head high two decades later. Carbon fiber is used for the bodywork on the 700 NRs sold to the public. But most incredible is its oval-piston V-4 engine that uses eight connecting rods and 32 valves to mimic a 750cc V-8. There is literally nothing else like it and probably never will be again.
