The Harley-Davidson FLS Softail Slim is a masterclass in minimalist design, channeling the spirit of 1950s custom bobbers while still delivering exceptional comfort and ride quality.
Its narrow rear end and trimmed front fender create a sleek, streamlined appearance, while the solo seat and minimal chrome trim evoke a sense of simplicity and elegance. The Softail Slim’s ergonomic design ensures a comfortable fit for riders of all shapes and sizes, thanks to its 23.8-inch seat height and spacious rider footboards.
Underneath its vintage-inspired exterior lies a robust powertrain, featuring Harley-Davidson’s air-cooled 1690cc Twin Cam 103B engine with Automatic Compression Release (ACR). This potent combination produces an impressive 97.4 ft-lbs of peak torque at 3000 rpm, making the Softail Slim a thrill to ride.
Whether you’re carving through twisties or cruising down the highway, the Softail Slim delivers a unique riding experience that’s both authentic and accessible.
