Although the Milwaukee company fielded several examples of this "experimental" motor in 1928, the H-D "hybrid" was not competitive with the Excelsior and Indian entrys. The Davidson brothers and William Harley watched helplessly as their Springfield rival won every National Championship race contested in 1928. Even the greatly diminished Excelsior company was able to advertise significant victories in both flat track and hillclimb events. With a resurgence in motorcycle sales as an incentive, H-D authorized the design of an entirely new 45 cubic inch race motor with the hope of regaining their formerly dominant position in American racing.
