The Honda Z50A is a small motorcycle with a 49 cc (3.0 cu in) single-cylinder four-stroke overhead cam engine and a semi-automatic transmission.

[1] The 1968 sometimes referred to as the "High Bar" or the "Slantguard", was the first of the Z50 series to be released to the American market.

Lower handlebars were fitted on the 1969/1970 K1 "short tail" as well as a license plate mount.

In 1972, after frame cracking became a growing issue, Honda incorporated rear suspension on the bike.

The Z50A "Soft Tail" remained on the American market until after model year 1978, when it was replaced by the Z50R.
