The Flathead V-twin engine was introduced in 1929, powering big twins until 1948 and smaller 45ci models until 1973. Used in legendary military bikes and the Harley-Davidson Servi-Car, the Flathead was known for its durability and simplicity.
Knucklehead (1936-1947) – The First Overhead Valve Engine
The Knucklehead V-twin engine revolutionized Harley's performance with overhead valves, improving power and efficiency. This engine powered classic models and set the stage for future Harley-Davidson motorcycles.
Panhead (1948-1965) – The Birth of Modern Harley-Davidson®
The Panhead engine introduced aluminum heads and improved oiling, making it one of Harley's most reliable designs. It powered models like the Hydra-Glide, a predecessor to today's Electra Glide.
Shovelhead (1966-1984) – A Power Boost for Touring Riders
With increased horsepower and better cooling, the Shovelhead engine became the heart of Harley-Davidson touring motorcycles, including early versions of the FLHX - Street Glide.
Evolution (EVO) (1984-1999) – The Engine That Saved Harley
The Evolution engine helped modernize Harley-Davidson motorcycles, delivering reliability and performance in models like the Heritage Classic, Fat Boy, and Softail lineup.
Twin Cam (1999-2017) – More Power, More Performance
Harley's Twin Cam engine offered better horsepower and a smoother ride, powering best-selling models such as the Road Glide, Street Bob, and Harley-Davidson Street Glide Ultra.
Milwaukee-Eight® (2017-Present) – The Future of Harley-Davidson®
The new Milwaukee-Eight is Harley’s most advanced V-twin engine, delivering more power, smoother performance, and improved cooling. Found in bikes like the ModelFLHX - Street Glide, ModelFLTRX - Road Glide, and the Pan America 1250 ST, it represents the future of Harley-Davidson®.
