The Honda SS125A was a motorcycle manufactured by Honda from 1967 through 1969.

The SS125A was based on the Japan only Honda CS125 along with two other variants, the CD125 and the CL125, all three of which shared many common components with the CS125. The larger capacity CD175 was also similar in design, up to 1969, although with more touring-orientated styling.

Although the variants shared common components, many were unique to this range and, combined with the relatively short production run, can make spare parts difficult to obtain today. Certain items, such as silencers (mufflers) for the low slung exhaust[1] are very rare and command a premium when sold.

In spite of its stylish appearance,[4][5] the motorcycle was criticised for lack of performance,[6] and was effectively superseded by the CB125 in 1971.

The SS125A had 17 inch wheels; the front rim was either 1.4 inches or 1.6 inches wide while the rear rim was 1.6 inches wide.[2] The 124 cc twin cylinder engine was basically same as the earlier CA95/CB92 layout,using the left side of the engine for the timing chain to the camshaft.[1] It used a Keihin Seiki vacuum carburettor, as opposed to the earlier engines,which were equipped with a slide valve type. The home market (Japan) version was built using a 180 degree crankshaft, as opposed to the 360 degree layout in the U.S.models.[3]
