Harley Davidson Bronx Prototype

Harley-Davidson plans to launch an exciting, all-new streetfighter motorcycle built for performance and speed. The Harley-Davidson® Bronx™ model amplifies speed, performance and thrill alongside features and benefits that are truly Harley-Davidson.

Powering both the new Pan America™ and Bronx models is the new liquid-cooled ‘Revolution Max’ 60° V-twin engine.  Created to power a range of new Harley-Davidson® models, the Revolution® Max is designed to offer flexible performance with a broad powerband that builds to a surge of high-RPM power. Minimizing weight and maximizing performance, the Revolution® Max provides a narrow powertrain profile that is integrated into the motorcycle as a stressed member of the frame to enhance center of gravity and handling. The fully balanced powertrain has an internal counter balancer that mitigates primary engine vibration to enhance rider comfort and improve vehicle durability. Its design is bold and contoured, classic and contemporary, strong and svelte – a representation of Harley-Davidson® performance and style.

The powerful all-new 60-degree V-Twin has been designed for a new range of Harley-Davidson motorcycles in two different guises – 1250cc in the new Harley-Davidson Pan America™ and 975cc in the Harley-Davidson® Bronx™.

Revolution® Max Engine Technical Features

Liquid-Cooled V-Twin Architecture
Since 1909 the V-Twin engine has been the centerpiece for legendary Harley-Davidson®.  This lineage continues into the middleweight performance space with the Revolution® Max engine.

A 60-degree vee angle of the cylinders provides space for dual down draft throttle bodies that maximize air flow and increase performance.
Liquid cooling maintains a controlled engine temperature for consistent performance in changing environmental and riding situations.

High Performance Development Collaboration – Braking and Tire

To optimize performance of the new Pan America™ and Bronx™ models, Harley-Davidson® tapped into the expertise of world class component manufacturers to deliver bespoke solutions for braking and tire performance. For braking, Harley-Davidson® collaborated with Brembo® to create a new radial monoblock four-piston caliper that combines sharp edges with softer curves designed to create a style that complements the personality of the bike and delivers outstanding braking feel and capability.

New partnerships with Brembo® and Michelin® support middleweight development.

For tires, Michelin® and Harley-Davidson® have worked closely to develop co-branded tires for each motorcycle model that optimize performance, feel and grip in all conditions.
