Indian Motorcycle, the first American motorcycle company, announced
the details of the all new Thunder Stroke 111⢠engine that will
power the model year 2014 Indian Motorcycle. 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.
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-lbs of torque, the 49-degree V-Twin engine is the new
heartbeat of Indian Motorcycle and marks the first clean-sheet
Indian Motorcycle 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.
"Everyone involved in the design of this motorcycle line
understands that we are the stewards and caretakers of one of
America's most storied and legendary brands. We've worked
tirelessly to retain the truly iconic characteristics of the brand
and combine those elements with advanced technologies to deliver a
new Indian Motorcycle offering exceptional performance and truly
unsurpassed reliability," said Polaris Industries Vice President of
Motorcycles, Steve Menneto. "The new Thunder Stroke 111 engine
delivers what riders are looking for, and we expect that Indian
Motorcycle fans will be inspired by this legendary new power plant
as we accelerate toward our full launch in the months ahead."
The new Thunder Stroke 111 engine has been extensively tested,
refined and proven by one of the industry's most rigorous
development and testing programs, accumulating over one million
miles of testing, including state-of-the-art dyno testing, and
hundreds of thousands of miles of on-road testing. The all-new
Thunder Stroke 111 is built in Osceola, Wisconsin at the Polaris
Industries Engine Assembly Plant, with future full unit motorcycle
assembly taking place in Polaris' state-of-the-art production
facility in Spirit Lake, Iowa.
