Historical Context

The 1979 Harley-Davidson FXS Low Rider marked a bold continuation of the factory custom movement that Harley initiated with the original Low Rider in 1977. Designed to capture the style and attitude of the chopper and street custom scene, the FXS combined the power of the Shovelhead V-twin with a lowered stance, drag bars, and cast mag wheels. It was also among the first Harley-Davidson models offered with the new 80 cubic inch (1340cc) Shovelhead engine, a significant update that gave riders more torque and smoother performance over the earlier 74ci versions. The 1979 FXS helped define Harley’s custom-cruiser identity during a time when the company was fighting for its place in a changing motorcycle market.

Project Potential

The 1979 FXS is a dream project for Harley-Davidson enthusiasts who appreciate vintage custom styling straight from the factory. Restoring this model to original specs means paying attention to unique details like the mag wheels, low-slung seat, and factory paint schemes with striping. It’s also a favored base for custom builds—many bobbers, choppers, and club-style bikes started life as an FXS. With strong aftermarket support for the Shovelhead motor and drivetrain, builders can easily find performance upgrades, period-correct components, or resto-mod enhancements to suit any vision.

Riding Experience

The 1979 FXS Low Rider provides a raw and satisfying riding experience. The 80ci Shovelhead engine delivers strong torque and classic V-twin rumble, while the 4-speed gearbox offers a traditional mechanical feel. The bike’s lower center of gravity improves handling in urban settings, and the front and rear disc brakes—though modest by today’s standards—offer reasonable stopping power. The seating position is aggressive but comfortable, thanks to mid-controls and pull-back handlebars, making it well-suited for both cruising and performance-oriented riding.

Legacy and Collectibility

As one of the original factory customs and the first Harley-Davidson models to feature the larger 80ci Shovelhead, the 1979 FXS holds an important place in the brand’s legacy. It represents a transitional period when Harley-Davidson was catering to a younger, style-conscious audience while still holding onto traditional mechanical design. Today, the 1979 Low Rider is highly collectible—particularly unmolested examples—and it’s admired for its mix of classic performance, custom looks, and historical importance. Restoring one is a commitment to preserving an influential chapter in American motorcycle culture.
