The C90 put a 90 cc overhead-cam single in the Super Cub step-through, giving the working Cub enough pace to keep up with traffic on open roads. It kept the three-speed semi-automatic gearbox, leading-link fork and enclosed chain, and carried the restyled forks and headlamp of the C50. Built with few changes for decades, it became a favourite of delivery riders, postmen and commuters.
