Considered by many as the ultimate masterpiece of American motorcycle production the Ace inline four-cylinder was designed by William Henderson of Philadelphia, the Ace produced circa 1920-24. While other companies offered fours, Ace scored top speed honors earning the accolade “Fastest Motorcycle in the World.” Ace’s fame was enhanced by Cannonball Baker’s historic 7-day cross-country run.

First appearing in 1920 and powered by a 1262-cc inline-four that produced 35 horsepower, the elegant 350-lbs. machine could reach 85-mph. Because of its exceptional sturdy design and construction it could accommodate a “flying chair” for passenger duties.

This restored example was purchased by Art Sigal in Ireland where it had received its restoration and later taken laps cruising around the Isle of Man with the British vintage club. It wears the distinctive blue paint and cream colored wheels and teamed with a British Watsonian sidecar, a correct combination after its original importation to Great Britain. The eminently rideable classic also shows a variety of accessories and instrumentation.

Now some 95-years “young,” it has been identified as one of three 1920 Aces known to exist and being serial number A1209, it is also believed to be the lowest numbered Ace in existence.
