Harley-Davidson Knucklehead 1943



Introduced in 1936, the Harley-Davidson Knucklehead was a groundbreaking motorcycle that set new standards for performance and style. Its distinctive overhead-valve engine, with its "knuckle" shaped rocker covers, gave it its nickname and became an iconic symbol of American motorcycling.

The 1943 Knucklehead was one of the last models produced before World War II halted production. It featured a number of improvements over earlier models, including a more powerful engine, a new frame, and a redesigned suspension.

The Knucklehead's engine was a 74 cubic inch (1,213 cc) V-twin with a compression ratio of 6.5:1. It produced 40 horsepower at 4,200 rpm and had a top speed of over 100 mph. The engine was mated to a three-speed transmission with a hand-operated clutch.

The Knucklehead's frame was a new design that was stronger and lighter than previous frames. It featured a double-downtube design with a welded-on rear section. The suspension was also redesigned, with a new front fork and a rear suspension with coil-over shocks.

The 1943 Knucklehead was a popular motorcycle with both civilian and military riders. It was used by the US Army during World War II and was also a popular choice for civilian riders after the war.

Today, the Knucklehead is a highly sought-after collector's item. Its classic styling and legendary performance make it one of the most iconic motorcycles ever built.
