1946 Harley Davidson

Old bikes like this have a certain soul that can’t really be described with words. It’s about sound, feel, smell, and the fact that they are windows into the past.

Good ol’ American engineering. Really cool to hear that machine came back to life so effortlessly. That’s a piece of history!!! Almost a 73 year bike running strong. Read more

1946 Harley Davidson Knucklehead

A legendary motorcycle. I love these machines! Kick starting a 1946 Harley Davidson Knucklehead.

The knucklehead is a retronym used by enthusiasts to refer to a Harley-Davidson motorcycle engine, so named because of the distinct shape of the rocker boxes. The engine is a two-cylinder, 45 degree, pushrod actuated overhead valve V-twin engine with two valves per cylinder.

Harley-Davidson Knucklehead

All this Knucklehead needed was a little TLC, a little gas and two kicks.

Speaking of “character” in a motorcycle, the thing I like best about this video is listening to the lovely throb from that knucklehead engine, either at idle or at speed. I wonder what levels of vibration the rider felt, especially at freeway speeds? Makes me wish HD still manufactured a comfortable, durable, good-cruising 61ci knucklehead. Read more

HARLEY DAVIDSON KNUCKLEHEAD 1946 FL

HARLEY DAVIDSON KNUCKLEHEAD

The knucklehead is a retronym used by enthusiasts to refer to a Harley-Davidson motorcycle engine, so named because of the distinct shape of the rocker boxes. The engine is a two cylinder, 45 degree, pushrod actuated overhead valve V-twin engine with two valves per cylinder.

It was the third basic type of V-Twin engine used by Harley-Davidson, replacing the Flathead-engined VL model in 1936 as HD’s top-of-the-line model. The engine was manufactured until 1947 and was replaced by the Panhead engine in 1948. The Knucklehead-engined models were originally referred to as “OHVs” by enthusiasts of the time and in Harley’s official literature; the nickname arose from the California chopper culture of the late 1960s.
