The Pierce Four was the first four-cylinder motorcycle produced in the United States.[5][6][7] The model is included in the AMA Motorcycle Hall of Fame Classic Bikes[1] and Barber Vintage Motorsports Museum. Touting its inline-four engine as "vibrationless", Pierce sold the motorcycle for $325,[2] rising to $400 by 1913, which was expensive at the time, making it popular with "more prosperous sportsmen".[8]

Development and design

Percy Pierce, president of The Pierce Motorcycle Company, created as a subsidiary of Pierce-Arrow Motor Car Company, had acquired a European 1908 FN Four and brought it to America to disassemble and study.[9] The company's engineering team used it as a "reference" for at least part of the two years they took to develop the Pierce Four.[4][10] The results were innovative, with a stressed member engine and shaft drive,[6] and a frame that both hid the control cables and held oil and gasoline internally.[11][12] The large diameter tubing is said to have increased strength and reduced parts count for less expensive manufacturing.[13] Unlike FN's engine, the Pierce had a T-head, and cam-driven intake valves rather than automatic (opened by atmospheric pressure).[5]

Early models had no clutch and fixed gearing, like the competing FN Four, but this was soon corrected in 1910 when a two-speed transmission was fitted.[6]

Fate of Pierce Motorcycle Company

The motorcycle is said to have cost more to build than its sale price and eventually bankrupted Pierce Motorcycle Company after fewer than 500 were built.[7]

Exhibitions and collections

The Pierce Four was exhibited in the Guggenheim Museum's The Art of the Motorcycle exhibition in Las Vegas.[14] Examples are held in permanent collections of several museums, including the National Motorcycle Museum in Iowa,[15] the Motorcycle Hall of Fame Museum in Ohio,[16] the Barber Vintage Motorsports Museum in Alabama,[17] and the Sammy Miller Motorcycle Museum in England.
