The new engine was publicly unveiled to a gathering of press and motorcycling fans on Saturday, March 9 at Daytona Bike Week. This marks yet another critical milestone in the company’s persistent drive towards a full launch later this year under the stewardship of Polaris Industries.

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.

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.

  1. Sorry about that. Please call 877.693.3572 to check on your status.

  2. NEVER RECEIVED MAY ISSUE

  3. Chris Janis says:

    The bottle top engine had a crank pin problem if i remember correctly. S & S had the fix. I believe the article was in AIM. Here’s hoping the new ThunderStroke 111 will work out well.

  4. Nicely done, they made an OHV motor look like a side valve antique.

  5. The current bottle top was based on S&S Cycles’ version of a Harley Evo with a custom looking rocker box I believe.

  6. The current bottle top engine was not a clean sheet design?
