As one of the most refined and ambitious motorcycles ever produced in America, this gorgeous, meticulously restored 1938 Indian Four model 438 represents the culmination of the Springfield marque’s long pursuit of smoothness, prestige and engineering sophistication. By the late 1930s, the Four had become the flagship of Indian’s lineup, less a machine and more a statement of artistry as the nation emerged from the Great Depression. Moreover, Indian Fours from the late-1930s stood alone in the industry as a platform unmatched by any other manufacturer at the time and are regarded among the finest machines ever produced. The Indian Four traced its lineage to the Ace motorcycle, developed by 4-cylinder pioneer William Henderson in 1919, following a brief stint at Excelsior, which had acquired his trailblazing Henderson brand two years prior. In 1927, Indian acquired Ace Motor Corporation, beginning its endeavor to incorporate and steadily refine the platform. With the demise of Excelsior in 1930, Indian became the sole maker of inline “fours” in the country, positioning it as the motorcycle of the most discerning enthusiasts. For the 1938 refresh, the Indian corrected its controversial inverted-valve configuration, the notorious “upside down” Four built from 1936–’37. The return to the traditional IOE (F-head) design restored the engine’s cooling efficiency and performance, reaffirming the Four’s reputation for effortless power and mechanical grace. Coming from The David A. Berg Collection and having been comprehensively restored by its previous owner, Eugene Keiffer, in 1998, this superb 1938 Indian Four features the numerous meaningful updates introduced to the model that year. Its 77 CI IOE inline 4-cylinder engine incorporates cylinders and aluminum heads cast in pairs, improving rigidity and heat management. Streamlined design features, from its sweeping fenders to its arrow-straight exhaust, reflected the era’s emphasis on airflow and modern styling, while a newly integrated dash with a waterproof switch, lighted ammeter and Corbin speedometer underscored the Four’s performance aspirations. Lastly, its leaf- spring front fork, sprung saddle, drum brakes and substantial wheelbase contributed to a stable, comfortable ride suited for high-speed touring. Advertised as “the smoothest motorcycle in the world,” the Indian Four was aimed squarely at selective riders accustomed to fine automobiles. With an estimated production of only around 300 model 438s, this exquisite 1938 Indian Four remains one of the most exclusive and unmistakably elegant motorcycles ever built. 1938 INDIAN FOUR
