Indian Motorcycle Delivers Most Powerful Engine In Its Class
Indian Motorcycle Delivers Most Powerful Engine In Its Class With New PowerPlus – A New Level Of V-Twin Performance From America’s First Motorcycle Company.
Indian Motorcycle, America’s first motorcycle company, raised the bar for American motorcycles today with the announcement of its most powerful engine to date, the PowerPlus. The all-new 1769 cc (108 ci), liquid-cooled V-twin delivers a class-leading 121 horsepower (90.1 kW) and 178 Nm of torque and establishes a dramatically new standard for American V-twin performance.
The PowerPlus will serve as the heart of the new Indian Challenger, an all-new, fixed-fairing bagger that utilises 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.”
The PowerPlus adopts several design and performance features from the liquid-cooled 1133 cc Indian Scout engine, including an overhead camshaft design utilising four valves per cylinder. But comparisons end there. The PowerPlus was developed with a big-piston, big-torque mindset with an end game of maximum power delivery across the entire curve.
The all-new powertrain features a six-speed transmission with true overdrive, assist clutch to reduce clutch effort, and three ride modes that allow riders to tailor throttle mapping to their riding preferences. Advanced technology also includes hydraulic valve lash adjusters and hydraulic camshaft chain tensioners for ease of maintenance and reliability.
The PowerPlus was tested, refined and proven by one of the industry’s most rigorous development and testing programs, accumulating over one million miles of simulated testing, including state-of-the-art dyno testing, and more than 250,000 on-road miles.
“You simply cannot deliver the ultimate bagger without an engine that stands head and shoulders above anything else in its class, and that was the motivation behind the PowerPlus,” said John Callahan, Indian Motorcycle Vice President, Engineering. “We developed the most sophisticated V-twin powerplant in the industry, and then we spent month after month, hour upon hour, putting it through the most intense paces to ensure it could take whatever we threw at it. The end result is something truly special.”
