Indian Four Model 441The Indian Four was not initially developed by Indian Motorcycle. Rather, this motorcycle's origin goes back to the '20s Ace, which was developed by the Henderson brothers. Following Will Henderson's death, Ace's assets were put up for sale in 1927, and Indian won the bid. Over a period of time, Indian rebranded the motorcycle and made it its own. In 1941, the Model 441 was launched as a touring motorcycle to give riders a smoother and more comfortable riding experience. In a world dominated by motorcycles with V-twin engines, the Model 441's four-cylinder engine with a 1,297 cc displacement set it apart. The motorcycle hit a top speed of 95 mph, which wasn't common for touring motorcycles at the time. It had a larger fuel tank that could accommodate 4.5 gallons of gas, allowing riders to travel long distances without refueling stops. Despite its popularity among motorcyclists of the time, the Indian Four Model 441 did not succeed in terms of long-term production. The onset of World War II caused Indian to refocus its priorities on developing and launching motorcycles for the military. This ceased the production of the Model 441. Today, the Model 441's distinct features, including its skirted fenders, rarity, and powerful engine, have made it a bit of a collector's item.
