Indian announces 111 cubic inch engine

Announced in the US on March 9 in conjunction with Indian and Victory's appearance at Daytona Bike Week, the all-new engine is set to debut in the 2014 Indian Motorcycle lineup, which will be launched in the US later this year, with Australia to follow - hopefully - soon after.

Since the April 2011 acquisition of Indian Motorcycle by Polaris Industries, the company has made an unprecedented commitment of time, resources and passion into the design of the all-new power plant. From the outset, the goal was to capture the iconic design and styling aspects of the 112-year old brand's most historic models and fuse that heritage with state-of-the-art technology and progressive design elements. The new design reflects an unparalleled investment into researching the complete history of Indian Motorcycle power train development, including the review of volumes of historical documentation, miles of riding vintage motorcycles, and studying and dissecting a broad array of legendary Indian Motorcycle models.

The Thunder Stroke 111 engine features 111 cubic inch displacement and delivers the raw power and iconic styling that have long been hallmarks of the legendary Indian Motorcycle brand. Delivering more than 115 ft/lb of torque, the 49-degree V-Twin engine is the new heartbeat of Indian Motorcycle and marks what Indian Motorcycle says is the first clean-sheet Indian engine design in seven decades.

With parallel pushrod tubes, finned heads, down firing exhausts, left side air intake, and the proportions and layout familiar to Indian Motorcycle fans around the world, the Thunder Stroke 111 is sure to inspire both experienced and new riders. The engineering prowess and financial resources of Polaris Industries will re-forge this iconic brand into the industry leader it deserves to be.
