1937 Indian Sport Four

Engine no. 468M

• Accurately restored with a magneto

Many manufacturers market a flagship model that showcases the technology of that particular company. In the case of Indian Motocycles, it was the four cylinder models that began when the company purchased the rights and tooling to the Ace motorcycle in 1927. They rarely turned a significant profit as a single model, and with Indian, police sales were hugely important. Still, the Indian Four sold to those of higher disposable income and perhaps the belief that they possessed a more refined taste in two-wheeled transportation. The Four was Indian's Packard.

The year 1936 was a significant year in the American motorcycle market. Harley-Davidson released their phenomenal OHV 61 V-twin, and Indian introduced a newly designed four cylinder engine, the first real change since the Ace engine. While the new Indian Four retained individual cylinders like in the past, they reversed the valve configuration to an exhaust over inlet pattern. The engineering reasoned that the hot exhaust valves would be in the cooler air stream, uninhibited by other engine parts, which in turn would increase the power of the engine. The new Series 436 would unfortunately be dubbed the "upside down Four".

Sales of the new Four flopped, topping out at about 300 machines when double was projected. Marching into 1937, the Series 437 Indian Four was mildly improved over the prior year. The biggest difference came in carburetion. Replacing the single Marvel carburetor were a pair of Zenith carburetors secured to aluminum "Y" manifolds onto the cylinders, a first in the American motorcycle industry. The exposed exhaust valve springs of the 436 were now covered to protect them from road debris. A revised frame moved the gear shift lever forward and all Indians received the new larger bayonet gas caps. Sales again were not what Indian expected and could have spelled the end of the illustrious Four forever.

The Series 437 Indian Four was marketed as the Sport Four. Its 77 cubic inch engine produced 35 horsepower and could propel the motorcycle to 90 mph. The "Upside Down Fours" have been maligned unfairly since they were first on the market, when in truth they did perform admirably and their twin mufflers were a standout, complementing the superb paint schemes. Modern riders of these motorcycles have all claimed they are great motorcycles and superior to the machines they replaced when new. Collectors have come to realize that these particular Indian Fours are very unique, rare and now highly desirable.

This 1937 Indian Four is flawlessly restored, resplendent in Indian Red with the optional "Arrow" tank panel design. The motorcycle was accurately restored with a magneto as indicated on its serial number. Paint and plating finishes are correct to the machine, clean and performed in the highest quality work.
