Harley Releases Details on Liquid-Cooled Revolution Max Engine Powering Pan America and Bronx Models

Harley-Davidson made some waves at EICMA this week, showing off two models it teased in 2018, the Pan-America adventure-tourer and the Bronx streetfighter. Both are powered by a new liquid-cooled 60-degree V-twin engine platform called the Revolution Max — 1,250cc in the Pan America and 975cc in the Bronx. Harley also confirmed that both models will launch in late 2020.

The Revolution Max is a bold new step for a company invested so heavily in (air-cooled) tradition — although perhaps not as bold as its LiveWire electric motorcycle unveiled earlier this year and now on sale at H-D dealerships nationwide. (Read our First Ride Review here.) Harley says the Revolution Max is designed to minimize weight and maximize performance, with a narrow profile that integrates into the bike as a stressed member of the frame. It also features a counter-balancer for smooth and comfortable operation.

Harley claims performance targets of more than 145 horsepower and 90 lb-ft of torque from the Revolution Max 1250, and more than 115 horsepower and 70 lb-ft of torque from the Revolution Max 975.

A few other details about the new Pan America and Bronx were released as well, including a collaboration with Brembo to create a new radial monoblock caliper that complements Harley’s unique design, and a continuing partnership with Michelin to develop co-branded tires specifically for each model.

Thanks to a smattering of new images (scroll down to see them all), we can also glean a bit more info about the new bikes.
