Few
Things You Should Know About Motorcycles
Last year, four
million motorcycles were in use in the United States alone. Whether
relied upon as a primary means of transportation, used to provide
weekend recreation, souped up and sped along for racing, or displayed
as antique, millions of people across the world have shown that the
novelty most definitely has not worn off
The Europeans
took the lead in developing the motorcycle in the early twentieth
century. One Englishman proclaimed his countrymen loved the cycle
because they enjoyed mechanical things. However, Americans enjoyed
their motorcycles as well.
Indian motorcycles
are still beloved enthusiasts claim that there are still 50,000 Indian
motorcycles on the road.Indian bikes might reach 60 m.p.h., but handbooks
cautioned riders to not exceed 10 m.p.h. through town. These early
handbooks are full of advice and etiquette for the motorcyclist.
Some period gems include: do not ride with the muffler open as the
noise scares restive horses, and worries invalids and nervous people,
do not run away in case of accident but stand by like a man don not
get rattled, and do not ride by a motorcyclist who is stalled by the
side of the rode as you may be in the same fix yourself some day.
History
As might be imagined,
the motorcycle evolved from a vehicle powered by sheer human energy
the bicycle. French bicycle maker Pierre Michaux and his sons Ernest
and Henri first fitted a bicycle with cranks and pedals precursors
to the modern-day motor in 1861. The Michauxes velocipede was an
instant hit and the family became the largest velo producer in Europe
with a large factory at Bar-le-Duc in France. Working with Michaux,
L.G. Perreaux devised a steam-powered motorcycle engine, called a
velo-a-vapeur, which was patented in 1868. Sylvester Howard Roper
of Roxbury, Massachusetts pioneered a similar invention in the United
States around that time as well.
Raw Materials
The primary
raw materials used in the manufacture of the body of motorcycle are
metal, plastic and rubber. The motorcycle frame is composed almost
completely of metal, as are the wheels. The frame may be overlaid
with plastic. The tires are composed of rubber. The seat is made
from a synthetic substance, such as polyurethane. The power system
consists of a four-stroke engine, a carburetor to transform incoming
fuel into vapor, a choke to control the air-fuel ratio, transmission,
and drum brakes. The transmission system contains a clutch, consisting
of steel ball flyweights and metal plates, a crankshaft, gears, pulleys,
rubber belts or metal chains, and a sprocket. The electrical system
contains a battery, ignition wires and coils, diodes, spark plugs,
head-lamps and taillights, turn signals and a horn.
A cylindrical
piston, made of aluminum alloy (preferred because it is lightweight
and conducts heat well), is an essential component of the engine.
It is fitted with piston rings made of cast iron. The crankshaft
and crankcase are made of aluminum. The engine also contains a cylinder
barrel, typically made of cast iron or light alloy
The Future
Motorcycles remain
popular and the collecting and riding of antique models is just as
popular as riding the new versions. While sleek, new versions will
continue to be produces, it is anticipated that the value of older
models will continue to rise.
Legal Definitions
A motorcycle
is broadly defined by law in some countries for the purposes of registration,
taxation or licensing riders as a two-wheel motor vehicle fit to
drive. Other countries distinguish between mopeds and other small
bikes and the larger, more powerful vehicles. In Canada and some
U.S. jurisdictions, three-wheeled motor vehicles fall under the auspices
of motorcycle regulations.
In the United
Kingdom, the rules on which motorcycle may be ridden by
whom are complex. A moped, which can be ridden
at age 16, has a maximum design speed not exceeding 50 km/h (31
mph) and engine capacity no greater than 50 cc. A learner motorcycle,
which can be ridden from age 17, has an engine up to 125 cc with
a power output not exceeding 11 kW (15 hp).
In New
Zealand, learner and restricted motorcycles may only have
a 250 cc engine capacity. This distinction draws some criticism,
as it allows 15-year-old learner riders to operate bikes capable
of reaching speeds in excess of 250 km/h (160 mph).
The legal age
to be eligible to apply for a New Zealand motorcycle licence is 15
years and over. New Zealand employs a three stage system for motor
vehicle licensing. At age 15, an individual can gain their first
licence known as their learner licence. They must hold this for at
least 6 months before they are able to move on to their restricted
licence. They must then hold this "restricted licence" for
one and half years. After a period of 6 to 18 months, depending on
age and additional training, a holder of a restricted licence may
sit the third and final stage known as the full licence. Until an
individual has their full licence they are only able to ride a motorcycle
which has an engine capacity of 250 cc or less.
The laws of some
countries allow anyone with a car licence to legally ride mopeds
not exceeding 50 cc in capacity, meaning that they do not need to
show any competency in handling such a vehicle.
The laws and regulations
for legal moped usage in the U.S. vary by state. The specifics of
the motorcycle and moped laws in the U.S. can be obtained from each
individual states Department of Motor Vehicles websites
In Australia You
must be at least sixteen years and nine months old before you are
issued with a Learner riders licence.You may book into and attend
a pre-learner course at the age of sixteen years and six months,
as Certificates of Competence for course attendance are valid for
three months from date of issue.
