John Hancox - Honda 250 six
Honda RB166 250cc Motorcycle Motorbike Racing Birthday Card by John Hancox
When in the 1960s, Suzuki and other manufacturers were producing two-stroke engines for Grand Prix racing, Honda preferred to stay with the tried and trusted four-stroke engine. The power difference at this stage had become enormous and Honda engineers had to work a way of producing more power from the less efficient four stroke process. The answer was more cylinders of a smaller bore.
This idea worked superbly and Hondas won the 125cc, 250cc and 350cc classes in 1962 and the 250cc and 350cc in 1963. By 1966 success was to come again with Mike Hailwood blazing to glory in both the '66 and '67 seasons.
