Revolution® Max

The new liquid-cooled 975cc and 1250cc Revolution® Max engine has a narrow profile that is integrated into the bike as a stressed member of the frame to enhance center of gravity and handling. The fully balanced powertrain has an internal counterbalancer that mitigates primary engine vibration to enhance rider comfort and improve vehicle durability.

Revolution® Max 1250 Engine Performance Targets

  • Displacement 1250cc
  • More than 145 horsepower
  • More than 90 ft. lbs. peak torque

Revolution® Max 975 Engine Performance Targets

  • Displacement 975cc
  • More than 115 horsepower
  • More than 70 ft. lbs. peak torque

Revolution® Max Engine Technical Features

  • Liquid-Cooled V-Twin Architecture
    o Since 1909 the V-Twin engine has been the centerpiece for legendary Harley-Davidson® motorcycles. This lineage continues into the middleweight performance space with the Revolution® Max engine.
    o A 60-degree vee angle of the cylinders provides space for dual down draft throttle bodies that maximize air flow and increase performance.
    o Liquid cooling maintains a controlled engine temperature for consistent performance in changing environmental and riding situations.

Brakes and Tires

Harley 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.
For tires, Michelin® and Harley-Davidson® have worked closely to develop co-branded tires for each motorcycle model.

The new models are expected to launch in late 2020.
