Major changes for 1928 Harley-Davidson models included a stronger fork and front brakes, which resulted in improved handling and a total-loss oil system fed from an oil tank concealed in the front half of the left fuel tank. The Harley-Davidson JDL Solo Sport had a 74 cubic inch engine.

1928 was also the first year for optional colors: Coach Green, Azure Blue, Police Blue and Maroon were priced at $24 (about $320 in 2012), while cream and white carried a $27 price tag.  The J series overhead valve V-twin was the basis for all the future 74 cubic inch and 80 cubic inch Harley big twins.
