Production of the machine was slow in the first year, but by 1922 the factory was going strong and Ace was on stable footing. Henderson was lauded for his successful designs. The Ace was successful in long-distance and cross-country contests. Erwin "Cannonball" Baker set a transcontinental motorcycle record on an Ace in 1922.
Henderson was tragically killed in a street accident when a speeding car came out of a side street and hit him while he was riding an Ace Sporting Solo.
