The Harley Davidson FLH Shovelhead, produced from 1966 to 1984, is an iconic American motorcycle that represents the peak of the "chopper" era. Known for its powerful and distinctive "Shovelhead" engine, this model offered riders a combination of raw power, classic styling, and enduring reliability. The FLH, standing for "Full Dress", designated the model as a touring motorcycle, equipped with a full fairing, saddlebags, and a comfortable rider seat. This model was the direct ancestor of the legendary Harley Davidson Electra Glide, with the "Electra Glide" nameplate being introduced in 1965 for the FLH model year. The Shovelhead engine, famous for its distinct sound and impressive torque, was a significant departure from previous Harley Davidson engines, featuring a redesigned cylinder head with a distinctive "shovel" shape, hence the nickname. These engines were known for their robust construction, with many units still running strong today, with proper care and maintenance. The 1981 Harley Davidson FLH Shovelhead was part of the final generation of this iconic model before the company transitioned to the Evolution engine in 1984. This particular model year benefits from several advancements made by Harley Davidson in the late 70s, including electric start, a new disc brake system on the front wheel, and the introduction of a larger fuel tank for increased range. The 1981 FLH also benefited from a redesign of the frame and suspension, resulting in a more comfortable ride. The 1981 Shovelhead represented a culmination of Harley Davidson's engineering progress, offering a powerful, comfortable, and reliable motorcycle that still holds its own against modern touring motorcycles. The 1981 Harley Davidson FLH Shovelhead remains a coveted classic, sought after by collectors and enthusiasts alike for its unique character and historical significance within the motorcycle world.
