The Honda Z50A was the second generation of Honda's Z50 Series mini bikes. Though its predecessor, the Z50M, was available in Europe and Japan a few years previous, in 1969 the Z50A was the first of the Z50 series to be released to the American market. Upon its release this bike was considered to be a significant leap in technology in comparison to other mini bikes on the market at the time. This was partly because of its efficient 50cm3 engine with semi-automatic transmission. The Z50A remained on the American market until 1978 when it was replaced by the Z50R. In Europe and Japan, the Z50A was renamed the Z50J in 1973, and remained on the market until 1999. The z50jp is still available in Japan and through exporters in the United Kingdom.
