What makes the Harley Davidson Motorcycle Engine Unique
Whether it be powering a police bike, a fully-dressed
touring machine or a raked chopper with a springer
front end, the Harley Davidson motorcycle engine is
a mechanical marvel that is quite unique. Presented
here is an article which offers several reasons why
the Harley Davidson motorcycle engine is so unique.
One of the first and foremost factors that makes the Harley Davidson
motorcycle engine unique is its appearance, or design. Although some
smaller-sized models have been produced by Harley Davidson through
the years, most of their cycles, including the engines are quite large in
Several different types of engines have powered Harleys through the
decades. In Harley's early years, most of the engines were known as Fheads and Flatheads, these were followed by Knuckleheads, then
Panheads, onto Shovelheads, then Evolution and Twin Cam engines.
The names of the different styles of Harley Davidson engines are largely
based upon the design of the various engines' cylinder heads and valve
covers. The flathead engine features flat, vented cylinder heads, the
knucklehead engine includes valve covers that look like knuckles, the
panhead engine features cylinder heads and valve covers that resemble
pans and the shovelhead engine features cylinder heads that look like
The Evolution engines that power motorcycles made from the mid-1980's
through 1999 feature more square-shaped cylinder heads and valve
covers, while the modern twin cam and Revolution engines feature radical
design improvements on the basic V-Twin engine.
In recent years, many other motorcycle manufacturers have begun
producing bikes that at first glance, could be mistaken for Harley
Davidson. These motorcycles feature fatbob-style gas tanks, wide front
ends, low frames and V-Twin engines. Upon closer inspection however,
one can see that the pseudo-Harley engines do not look as solid and
workhorse-like as real Harley engines.
Another factor that makes the Harley Davidson engine unique is its
distinctive sound. Often described as throaty, the sound of a Harley
engine is unmistakable. The deep, rumbling and muscular sound
produced by their engines is one of the features that makes some people
want to buy these motorcycles. Some riders like to accentuate the sound
of their bike by installing custom exhaust systems. These exhaust
systems usually alter the sound made by their engines, with some
increasing the volume of the engine noise and others adding a different
tone to the engine sound.
The sounds that are produced by the other brands of motorcycles that
resemble Harley Davidson do not possess the same powerful rumble that
they are known for.
Harley engines maintain a well-deserved reputation as being some of the
best-designed and engineered motorcycle engines made anywhere.
These engines are designed to last and all of the parts, or components
are high quality, precision-made parts.
As with every facet of the experience, the engines on these motorcycles are
legendary and steeped in tradition. With many decades of experience in
producing some of the world's most respected motorcycles, Harley
consistently strives to produce technologically-advanced engines that
remain true to the tradition that these machines have built over the years.
Some people are so fond of their engines, that they get images of them
tattooed on their bodies. Rock bands are even named after specific
Through the years, Harley Davidson motorcycles have garnered an image
that promotes rugged individualism and American freedom. Movies,
television programs and popular music have promoted the image of these
motorcycles as being macho and sexy in nature. All over the world, this
image is celebrated and upheld and the sound of their motorcycle
engines can be heard in communities of all sizes.
