The 1970 - 1971 CB350 (K2 and K3 era) carried on with the same 325 cc twin, five-speed gearbox and drum brakes, with Honda making mostly cosmetic changes plus suspension and brake refinements over the run. These years were the model's sales peak in America, where it suited both new riders and commuters.
