Indian’s Thunder Stroke 111 Engine

  • 1920 Scout Indian’s middleweight model (the Chief being the biggest).
  • 1929 402 Four Cylinder An impressive bike built from 1928 to 1942. Company executives do not rule out a similar four-cylinder model in the future.
  • 1950 Chief Blackhawk One of the last of the original Indians. Introduced in 1922, the top-of-the-line Chief was Indian’s most powerful

With a new engine, a new motorcycle, and a new owner, Indian is ready to take on it’s old cruiser rival. 

When Steve Menneto, vice president of motorcycles at Polaris Industries, unveiled Indian’s all-new Thunder Stroke 111 engine at Daytona Bike Week in March, motorcycle enthusiasts were giddy with anticipation. Polaris bought the nearly dormant Indian Motorcycle brand in 2011. Would the company be able to revive it? The undeniably beautiful piece of engineering didn’t disappoint. But Indian’s new Thunder Stroke also represents something deeper for throttle twisters: the restoration of one of America’s most iconic motorcycle brands.

The original Indian motorcycle company was once a superstar. After its founding in 1901, Indian’s bikes went on to win major international racing victories, and by the 1910s the company was the largest motorcycle manufacturer in the world. Indian was technically innovative, too, introducing the first electric starter in 1914 and its first four-cylinder bike in 1927, providing serious competition for its principal American rival, Harley-Davidson.

Then disaster struck when management made a series of terrible business decisions, plunging the company into bankruptcy in 1953. For decades the brand foundered, with rights to the name changing hands numerous times and no all-new bikes being made until the late 1990s. Despite paying homage to the original Indian’s flamboyant art deco styling, with its deeply valanced fenders, these newer Indians lacked advanced engineering and sales subsequently lagged.

“When I started at Polaris in 2008, we brought in the consulting firm McKinsey,” Scott Wine, CEO of Polaris Industries, says. “Their analysis said we built great bikes but could use a great name. That led to the acquisition of Indian.” Using experience from its modest-selling Victory motorcycles and successful portfolio of off-road vehicles, Polaris began a fast-paced programme to completely re-engineer the Indian bikes and their engines, forgoing any parts sharing between its two motorcycle brands.

Every memorable motorcycle is built around a great engine, and Polaris has made a large investment in making the all new Thunder Stroke 111 motor a force to reckon with. The engine’s architecture and exterior sculpting echo classic Indian engines with their parallel pushrods and downward-facing exhausts. Engineers say it will produce a ground pounding 156 N.m of torque, and it’s no accident that the 1 820 cm3 V-twin is slightly bigger than Harley’s grandest engine, the 1 793 cm3 twin cam.

Menneto is confident in Indian’s future prospects. “We’re capable of giving Harley a run for its money in technical features,” he says. The all-new Indian bike will bear the brand’s heralded Chief model name. With the price starting at $18 999 (about R190 000) in the US, Indian executives say they can break even by capturing just 4 or 5 per cent of the heavyweight cruiser market. That’s not enough to cause panic in Milwaukee, where Harley oversees the company’s 57 per cent overall market share, but the bosses in Wisconsin can’t be sleeping easy with the thought of their old rival and freshly engineered Indian machinery hitting the roads.
