About this vehicle

YALE motorcycles were produced by the YALE Lock Company of Toledo, OH from 1902 to 1915. Two models were produced; a 6.5 horsepower V-twin and a 3.5 horsepower single cylinder model represented here. This motorcycle has a single-speed belt driven transmission and a handlebar mounted twist grip throttle control that operates through 12 separate rods and linkages to connect it to the carburetor. The cycle also incorporates innovative removable frame sections to allow fast and easy repairs in case of damage. It also has a crankcase window permitting the oil level to be visually inspected, innovative suspension forks, and acetylene lighting.
