C70 Passport and Honda 70 Generations
The C70 name does not describe one universal specification. Early C70M/Honda 70 machines, later U.S. C70 Passport models and other-market Super Cub equipment were cataloged separately. Honda changed engine, ignition, shift-system, body and equipment details over time. Coverage is deepest for 1980–1983; individual listings also cover 1971–1972 and other year slices.
