POWERPLUS ENGINE

We've raised the bar with our most powerful engine to date, the liquid-cooled PowerPlus. With two different sizes, 108 Cu-In making 122 hp and 128 ft-lbs of torque and the brand new 112 Cu-In engine making 126 hp and 133 ft-lbs of torque.

KING OF THE BAGGERS CHAMPION

The PowerPlus engine design is backed by performance proven in the most demanding environment — racing. Our 112 cubic inch PowerPlus dominated the larger displacement competition en route to winning the 2024 MotoAmerica King of the Baggers Championship on an Indian Challenger, making Indian Motorcycle the only three-time Champion.

MODERN PERFORMANCE

We put the PowerPlus through the industry's most rigorous development and testing program. We piled on almost one million miles of simulated testing, including state-of-the-art dyno testing and over 250,000 miles on the road.

ICONIC HERITAGE

A nod to Indian Motorcycle’s iconic history, the PowerPlus motor is named after one of our original motorcycles, produced from 1916 to 1924. It dominated board track racing, and Burt Munro would achieve his famous speed record of 190.07 MPH in 1967 on a modified Scout with a 37-inch PowerPlus engine.

POWER YOU CAN DEPEND ON

The PowerPlus motor's overhead camshafts and four valves per cylinder deliver incredible V-twin power. Hydraulic valve lash adjusters and hydraulic camshaft chain tensioners make it easy to maintain and reliable.

PERFORMANCE AT YOUR COMMAND

The PowerPlus engine has not only pushed rider-focused handling to the forefront of its time but has also claimed multiple victories on the track with its high revving race inspired design, including the three King of the Baggers Championships.
