Indian Motorcycle Announces the PowerPlus, the Most Powerful Engine in its Class


Indian Motorcycle unveils its most powerful engine to date: The PowerPlus. The all-new 108 cubic inch, liquid-cooled, V-twin engine delivers a class-leading 122 horsepower and 128 ft-lbs. of torque.*

The PowerPlus will power an upcoming model, an all-new, fixed-fairing bagger that utilizes Indian Motorcycle’s state-of-the-art technology to become the highest-performing American V-twin ever developed. The new engine’s name is a nod to Indian Motorcycle’s iconic history, paying homage to the Indian PowerPlus motorcycle produced from 1916 to 1924.

“We challenge our engineers with the notion that anything less than best-in-class design and performance will simply not get it done, and it’s clear with this new engine that they have delivered on that high standard,” said Steve Menneto, Indian Motorcycle President. “Countless hours were spent in design, development, and testing to ensure this is the best liquid-cooled V-twin ever developed, and I could not be prouder of our team and this incredible motor.”
