The Chief was introduced for 1922 to replace the Powerplus, although the Powerplus was continued under the "Standard" name until 1923.
Designed by Charles B. Franklin, the Chief had design features similar to Franklin's earlier Scout, including the gearbox bolted to the engine casings and primary drive by gear train.
The Chief had a bore of 3 ¹⁄₈ inches (79 mm) and a stroke of 3 ³¹⁄₃₂ inches (101 mm), giving a displacement of 61 cubic inches, as the Powerplus/Standard had.
 Unlike the Powerplus/Standard, the Chief was not offered with rear suspension.

The Big Chief was introduced for 1923.
 The engine of the Big Chief was bored to 3 ¹⁄₄ inches (83 mm) and stroked to 4 ⁷⁄₁₆ inches (113 mm), giving a displacement of 74 cubic inches.
 The Big Chief had mainly been offered for sidecar use, but was popular with solo riders as well.
The smaller-engined Chief was discontinued in 1928, partly to accommodate increased production of the Model 101 Scout.
