1931 Harley Davidson VL74 Engine

The 1931 Harley-Davidson VL74 was the first year for the VL model, a twin-flathead which was one of the most popular touring bikes Harley ever produced. It was designed to replace the pocket-valve engine in the Model J they had been building since 1911. Soon considered reliable and sleek the VL 74 captured the imagination of motorcyclists worldwide and established new standards for the industry.

It  was introduced during the Great Depression, a time when many motorcycle manufacturers struggled to survive. Harley-Davidson responded to the economic challenges by introducing the VL series, which featured a larger, more powerful V-twin engine to attract riders looking for performance and reliability.  They ended up producing 4 models, the V was the standard, the VL had a higher compression engine, the VS was geared for sidecar work, and the VC had cast iron pistons for the 3-wheeled Servi-Car.

The VL series, including the VL74, helped solidify Harley-Davidson's reputation for building durable and powerful motorcycles. The innovations and design elements from this era influenced future Harley-Davidson models and contributed to the brand's long-standing legacy in the motorcycle industry. It is still a highly collectible motorcycle, prized for its historical significance, classic design, and engineering. Well-preserved or fully restored models are especially sought after by collectors and vintage motorcycle enthusiasts.
