EmailJacksonville, FL — An eclectic mix of rare, exotic and sometimes peculiar two-wheelers will comprise the “It’s Complicated” motorcycle class at the March 5-8 Amelia Island Concours, the event’s silver anniversary.

Perhaps the most bizarre of the nine motorcycles in the class is the feet-forward, hub-center steering front wheel 1922 Ner-A-Car. With its pressed steel frame, the model was “nearly a car.” More than 6,500 were built in the United States and Britain.
The low-slung, steel-channel perimeter frame and hub-center steering contributed to the Ner-A-Car’s exceptional stability. Edwin G. “Cannonball” Baker rode a Ner-A-Car from New York to Los Angeles in 1922. The 3,364.4-mile enduro took a record-setting 174 hours. Despite its unusual appearance and design, the Ner-A-Car worked mechanically and dynamically, if not commercially.
More recently, Ducati engines have enjoyed a reputation for exquisite engineering. The 125 cc Gran Prix Desmo three-cam Ducati features an unusual method that both opens and closes its valves. The desmodromic — Desmo — valve train system does not use springs to close or open the valves. It employs three cams and has a valve-closing lobe that practically eliminates the possibility of valve float which can afflict high-revving engines. It has become a Ducati engineering trademark that has even found its way into the company’s potent marketing DNA.
Ariel’s Square Four promised the dynamics and trimness of a vertical twin mated to the smoothness, flexibility and performance of a multi-cylinder design. In 1953, the ‘four pipe’ 997 cc Ariel Square Four Mk II was released, with separate barrels and a redesigned cylinder head with four separate exhaust pipes.
But the price of the MkII Square Four strayed into automotive realms. By the late 1950s a new generation of high performance British twins and the nascent Japanese motorcycle industry eased the Square Four aside, and production of the MK II (1953-1959) ceased. But it remains a cult classic and one of the most desirable British exotics.
