Harley Davidson Facts

Did you know this one?

In order for any motorcycle to be referred to or represented as a
HARLEY-DAVIDSON motorcycle, it must fulfill both of the
following conditions:

1. It must have been initially assembled in its entirety by
Harley-Davidson Motor Company; and

2. It must be equipped with three critical components installed by
Harley-Davidson during the motorcycle's original manufacture (or with
genuine HARLEY-DAVIDSON replacement parts for such components): the frame,
the crankcases, and the transmission.

This means if you change your frame to an after market frame, or change to a non- H-D transmission or change to after market crankcases you are no longer riding a Harley

Most motorcyclists will not even remember the war between Indian and Harley-Davidson. The war, begun in 1903, did not end until 1954 when Indian stopped production with these words delivered to its loyal dealers:


"The management of the Indian company has just completed a study of conditions adversely affecting motorcycle production in the United States. This has led to a decision to suspend assembly of complete motorcycles at Springfield during 1954."

In 1917, Indian introduced the Model O whereupon H-D introduced the WJ Sport Twin. Both of these models used horizontally opposed engines similar to what BMW would introduce in 1923. The Model O soon became known as "Model Nothing" since it was viewed as too practical, small, and quiet. The H-D version had an engine twice the size of the Model O. Neither model proved popular in the USA.

Indian normally used names for its models while H-D used letters and numbers. This strategy seemed to work for Indian when it introduced the Scout, as it became a runaway seller.

Other motorcycle companies were also involved in this struggle. The Henderson brothers had produced the 4-cylinder Henderson motorcycle. It was bought later by Excelsior. Then, one Henderson brother left Excelsior and formed his own company, Ace, where he refined the 4-cylinder machine further. Ace soon went out of business and Indian bought manufacturing rights to the Ace. It shortly became the Indian Ace and then the Indian Four. Harley-Davidson considered making a 4-cylinder version also but abandoned the idea. The Ace never really caught on except for police use and did not appear in the catalog after World War II.

poems that were popular early on about this rivalry. Here's one:


"You'll never wear out
The Indian Scout,
or its brother,
The Indian Chief.
They're built like rocks
To take hard knocks.
It's the Harleys
That cause the grief."

In 1932, H-D introduced the 3-wheeled Servi-car. This had a motorcycle front end but two wheels behind, the forerunner of the modern trike. This vehicle came on the scene mainly for use by garages that always had to send two men out to get a customer's car for service and return it.

With the Servi-car, there was a way to attach it to the back of the car and tow it, thereby only requiring one man. It was also used by parking meter patrols and other utility uses. In the next year, 1933, Indian had its own version called the Dispatch Tow.

When it was realized that passengers liked being a little closer to the rider and not perched on the rear fender, the rider's seat was lengthened and became the Buddy Seat on Harley and the Chum-Me Seat on the Indian.

The controls on Harley-Davidson and Indian motorcycles were reversed. When each began vying for government contracts, they realized that each needed to have an option to place the controls on the other side of the bike. So each manufacturer had an option to have controls the same as the other's regular controls.

The Knucklehead model E Harley-Davidson was produced in 1936. Indian then came out with the "Improved Four" machine. In 1949, Harley released the FL Hydra-Glide "panhead" motorcycle. This was the first machine since the old Sport Twin to have a name associated with it.

In 1973 To the Mid 1990’s Halrey was building bomb casings in its York Plant the plant was aquired from AMF in 1973 and the plant had a contract to build bomb castings for the military

Harley built Bicycles from 1917 to 1923 Nine models were made under the Harley-davidson name. Six mens models and two ladies models, and a boys model were built. The Adult models had 26” or 28” wheels. The boys’ model 20” wheels.

Harley also built commercial and marine Motors. The first stationary model was built in 1905. and was reffered to has the “Buckboard model”. It was a single cylinder, 35” Harley Motorcylce motor. it was designed to be bolted down to a surface it could be used for a veriaty of tasks such as a knife sharpener or it could run a windmill, or saw, or water pump.

In the late 20’s to early 30’s A purpose-built stationary engine was developed and sold. It had a single-cylinder engine but was not derived from motorcycles. The engine contained an internal gas tank and you started it by hand like a model “T”

In the 1920’s to early 30’s There was the Harley line stripper. It was a Harley JD V-Twin solo bike with a sidecar holding a large tank and sprayer attatchments. It is not known if more then one was ever produced.

In World War II, Harley experimented with buiding engines for high speed mini tanks for the Canadian Military. the project never made it the mini tank engine was two 74-cubic inch Knuclheads joined together front to back with a differential. Harley also had a contract to develop a flathead based generator for the US army. The generator was to be pulled behind a Jeep or truck. The unit was developed and built but the 5,000 unit production contract was never filled has the war ended. More recently Harley produced two stage rockets.

Harley-Davidson Uses Geomagic to Recreate a Classic Dyna Wide Glide Part

From Peter Fonda in Easy Rider to buttoned-down executives seeking weekend thrills, Harley-Davidson motorcycles are an American icon, with a design aesthetic recognizable anywhere in the world.

The design of a Harley is so intricate that the models for many of its parts are sculpted with clay, wood or fiberglass to simulate the soft curves of the bike. Capturing the exact look and feel within traditional 3D CAD systems is difficult at best. As a result, integrating the handcrafted components into a modern CAD-engineered bike can be a time-consuming and expensive process of trial and error.

A new process, however, has the potential to significantly improve the way Harley-Davidson captures and duplicates legacy parts. Using Geomagic Studio software from Raindrop Geomagic (Research Triangle Park, N.C.), a Harley engineering consultant digitally duplicated a legendary Harley gas tank, increasing the speed and accuracy of the 3D modeling process, and enabling the company to create a digital inventory of the part.

Duplicating a Legendary Gas Tank

For most vehicles, a gas tank is simply utilitarian. Not so for the Harley-Davidson Dyna Wide Glide. The tear-drop-shaped gas tank is one of the most integral parts of the Dyna Wide Glide, designed 20 years ago by Willie G. Davidson as the first "factory chopper" motorcycle. The Dyna Wide tank was originally sculpted in wood because its soft-curving shapes were too difficult to reproduce accurately in CAD software.

A few years back, Harley-Davidson Engineering turned to Mark Schaefer of Advanced Design Concepts (ADC), a 3D modeling and CAD service bureau, to create computer surface models for the deceptively complex gas tank. Surface models would allow Harley-Davidson to integrate design and production of the gas tank with the rest of its CAD processes.

"We were familiar with the difficulty of this task," says Schaefer, who started out using commercial surface modeling software. "Styling is what drives Harley-Davidson's designs. Most of their styled models begin as clay models that need to be converted into CAD models for engineering design and manufacturing."

ADC's early surfacing efforts helped streamline the gas tank production process, but it was still tedious work to get the models within the accuracy range required by Harley-Davidson. It wasn't until turning to Geomagic Studio that ADC was able to deliver a solution that has the potential to deliver the CAD integration, accuracy and flexibility that Harley-Davidson has been seeking for its legacy parts.

Dyna Wide Goes Digital

The process started with Harley-Davidson sending Schaefer an assembly-ready Dyna Wide gas tank. It took two days of work to prepare the tank and scan it with an ATOS white-light 3D scanner. The 3D point cloud data was brought into Geomagic Studio, converted to a polygonal model, then a NURBS model, and exported as a watertight, manufacturable IGES surface. This process took a few hours, compared to three or four days with ADC's previous surfacing tool.

In the final step, Pro/ENGINEER was used to add parametric features such as mounting brackets to the model. The entire process was completed within four days. The surface accuracy of the model came within 0.003-inch of the original gas tank. "In the past, I had to work pretty hard to get models in the 0.010- to 0.015-inch range," Schaefer says.

Enticing Possibilities

Digital inventory of parts opens up enticing possibilities for manufacturing companies such as Harley-Davidson. The 3D data can be used to spin off different designs, products and applications with no duplication of effort. Substantial cost savings can be realized by having conceptual work, fit testing, and iterative redesign done on a computer. Replacement parts can be manufactured as needed, saving on warehousing costs, and avoiding the risk of damage and deterioration of aging legacy parts.

Perhaps the most exciting part of a digital inventory is the potential for companies to mass customize to the point where each product is as unique as the person who buys it. This would allow companies such as Harley-Davidson to provide customers with their latest products in an almost unlimited range of colors and styles.

Imagine all types of Harley enthusiasts – from the rebel to the weekend warrior – being able to select a Harley that perfectly fits their personality

An old rumour, which last surfaced in 1997, has been spreading on the Internet involving Elvis Presley and a 1950s Harley with an inscribed plaque under its seat. Depending on which version you hear, the plaque allegedly states "To Elvis, Love, Priscilla" or "To Elvis, all my love". The bike has been owned for several years by a man in south Wales, purchased by someone’s cousin near Salisbury or found in a garage sale in Vermont. The mysterious owners have been offered anything from $250,000 by a Harley-Davidson dealer through to $5 million by Harley’s C.E.O. The true identity of the bike was only discovered when the new owner ordered his or her first part, or was it when the bike was taken in for a service?
It’s a classic tale of an ordinary person being in the right place at the right time. But, despite several enquiries to Harley-Davidson’s UK office in recent weeks from leading TV journalists and inquisitive members of the public, the story is not true.
Elvis Presley did own a Harley-Davidson, many in fact, and Harley-Davidson Inc. did buy one, a 1956 Harley-Davidson KH which is now housed in the company’s archive facilities in Milwaukee. The Graceland Museum in Memphis, Tennessee, also has four Harley-Davidsons in its collection that were owned by Elvis.
