Speed records in the bicycling world date to the earliest days of their invention, and innovative methods of shielding the record challenger from headwinds saw great advancement with widespread availability of the motorcycle. Before long, two-wheeled vehicles were built expressly for this purpose, placing the motorcycle’s pilot as far rearward as possible, giving the cyclist, or “stayer,” the greatest benefit of his slipstream.

This four-cylinder motorcycle was constructed by Altos circa 1925 and, according to notes on file, was used in the establishment of a speed record of 120.958 kph by successful French cyclist Jean Brunier on November 1, 1925, at the Velodrome at Montlhéry in France. To attain this speed, the vehicle was specially clad with aerodynamic aluminum panels and fitted with an extended handlebar setup, allowing the pilot to control it from a near-standing position.

Acquired with the rest of the Schlumpf Reserve Collection by the Mullin Collection in 2008, this fascinating, unrestored vehicle, if not unique, is surely one of few survivors of its type, and hails from the heyday of the motor pacing sport.
