The SST-250 had a single brake disc with single caliper placed on the left side and the SST replaced its predecessor SS-250 in Europe while in North America the older SS-250 with a brake drum in front was still sold. A SST-175 was never available but a hanful of SST-350 in 1978.

They also changed the embroidery pattern on the seat and added aluminum stripes to the side compared to the SS-250. There were matching decal stripes to the gas tank on the side covers and the chain guard was painted in a matching color as well. The round clutch cover now had an “AMF Harley-Davidson” imprint, but otherwise was the same bike as a SS-250. Later 1977 models where also fitted with a larger generator to produce more power. If you look closely to the left engine cover hiding the generator you can tell later versions with a larger generator. (Compare pictures No. 1 and No. 3).

Colors: The bike was available in black, in sparkling blue, in red and sparkling brown. The decal design from 1976 was kept in 1977 also.
