Honda RC166 illustration by Bentley designer Frederic Dams.
Here’s his summary: “The 1966 Honda RC166 didn’t just win several 250cc titles, it’s one of the worlds most amazing engineering marvels. It had 6 cylinders, 4 cams, 24 valves, 6 carburettors, revved to 20.000 rpm and made 65hp. Extrapolate that to 2 litres and you’re talking 520hp, over 50 years ago and not a turbo in sight! Merc A45 AMG eat your heart out!!!”
