Yale Model 37
Years: 1913 – 1914
Yale belonged to America’s brass-era cohort, producing singles and twins that explored the boundaries of ignition, lubrication, and belt/chain drive. The machines appealed to early adopters who needed dependable travel on rough roads. While the brand did not survive industry consolidation, surviving Yales show careful period craftsmanship and document the rapid evolution from motor-bicycles to true motorcycles.
