..Types of motorcycles..
Sport bikes, cruisers, scooters, and touring bikes are some of the many types of motorcycles.
There are many systems for classifying types of motorcycles , describing how the motorcycles are put to use, or the designer's intent, or some combination of the two. [1] Six main categories are widely recognized:
cruiser, sport, touring, standard, dual-purpose, and
dirt bike. [2][3][4][5] Sometimes sport touring
motorcycles are recognized as a seventh category. [1]
Strong lines are sometimes drawn between
motorcycles and their smaller cousins, mopeds,
scooters, and underbones, [6] but other classification
schemes include these as types of motorcycles. [7]
There is no universal system for classifying all types
of motorcycles. There are strict classification systems
enforced by competitive motorcycle sport sanctioning
bodies, or by certain legal jurisdictions for motorcycle
registration, emissions, road traffic safety rules or
motorcyclist licensing . There are also informal
classifications or nicknames used by manufacturers,
riders, and the motorcycling media. Some experts do
not recognize sub-types, like naked bike, that "purport
to be classified" outside the six usual classes,
because they fit within one of the main types and are
recognizable only by cosmetic changes. [8]
1..Street..
Street motorcycles are motorcycles designed for being
ridden on paved roads. They have smooth tires with a
light tread pattern and engines generally in the 125 cc
(7.6 cu in) and over range. Most are capable of
speeds up to 100 mph (160 km/h), and many of speeds
in excess of 125 mph (201 km/h).
2..Standard..

Standards, also called naked bikes or roadsters , are
versatile, general purpose street motorcycles. [1] They
are recognized primarily by their upright riding
position, partway between the reclining posture of the
cruisers and the forward leaning sport bikes. [3] Foot
pegs are below the rider and handlebars are high
enough to not force the rider to reach far forward,
placing the shoulders above the hips in a natural
position. [2] Standards are often recommended to
beginning motorcyclists due to their flexibility,
relatively low cost, and moderate engines. [1]
Standards usually do not come with fairings or
windscreens, or if they have them, they are relatively
small. [1] Standard is often a synonym for naked bike,
a term that became popular in the 1990s in response
to the proliferation of fully faired sport bikes. The
standard seemed to have disappeared, fueling
nostalgia for the return of the Universal Japanese
motorcycle (UJM), [1] which were admired for their
simplicity, quality, and versatility. [3][4][6]
Muscle bike is a nickname for a motorcycle type,
derived from either a standard or sport bike design,
that puts a disproportionately high priority on engine
power. [1][9][10] Roadster is another common term
equivalent to standard or naked. [11]
3..Cruiser..

Cruisers are styled after American machines from the
1930s to the early 1960s, such as those made by
Harley-Davidson , Indian , and Excelsior-Henderson . [1]
Harley-Davidsons largely define the cruiser category,
and large- displacement V-twin engines are the norm,
although other engine configurations and small to
medium displacements also exist. [1] Their engines are
tuned for low-end torque, making them less
demanding to ride because it is not necessary to
shift as frequently to accelerate or maintain control.
[12] Cruisers are sometimes called "custom" even in
the absence of aftermarket modifications.
The riding position places the feet forward and the
hands are up relatively high, so that the spine is erect
or leaning back slightly. [1][3] At low to moderate
speeds, cruisers are more comfortable than other
styles, [3][4] but riding for long periods at freeway
speeds can lead to fatigue from pulling back on the
handlebars to resist the force of the wind against the
rider's chest. [13] Cruisers have limited cornering
ability due to a lack of ground clearance.
4.. CHOPPER..

.Choppers are a type of cruiser, so called because they
are a "chopped", or cut-down, version of a production
cruiser. Choppers are usually custom projects that
result in a bike modified to suit the owner's ideals,
and, as such, are a source of pride and
accomplishment. Stereotypically, a chopper may have
raked-out forks, small fuel tanks and high handlebars.
Choppers were popularised in the Peter Fonda film
Easy Rider . Being designed primarily for visual
effect, choppers will not usually be the most efficient
riding machines.
Power cruiser is a name used to distinguish bikes in
the cruiser class that have significantly more engine
output, around 80–100 hp (60–75 kW) as opposed to
about 50–70 hp (37–52 kW). They often come with
upgraded brakes and suspensions, better ground
clearance, and premium surface finishes, as well as
more exotic or non-traditional styling.
4..Sport bike..

Sport bikes emphasize speed, acceleration, braking,
and cornering on paved roads, [3][5][14][15] typically
at the expense of comfort and fuel economy in
comparison to less specialized motorcycles. [1][6]
Because of this, there are certain design elements
that most motorcycles of this type will share. Sport bikes have comparatively high performance engines
resting inside a lightweight frame. Inline-four engines
dominate the sport bike category, with V-twins having
a significant presence, and nearly every other engine
configuration appearing in small numbers at one time
or another. [1] The combination of these elements helps
maintain structural integrity and chassis rigidity. [1]
Braking systems combine higher performance brake
pads and multi-piston calipers that clamp onto
oversized vented rotors. [1] Suspension systems are
advanced in terms of adjustments and materials for
increased stability and durability. [1] Most sport bikes
have fairings , often completely enclosing the engine,
and windscreens that effectively deflect the air at
very high speeds, or at least reduce overall drag. [1]
Sport bikes have high foot pegs that position the legs
closer to the body to improve ground clearance when
cornering, and a long reach to the hand controls, which
positions the body and center of gravity forward,
above the fuel tank. The rider leans forward into the
wind, the force of which can comfortably support the
rider's weight at speeds near 100 mph (160 km/h), but
at lower speeds leaves too much weight on the arms
and wrists, causing fatigue.
Streetfighters are derived from sport bikes, originally
being customized sport bikes with the fairings
removed and higher handlebars replacing the low clip-
on handlebars. [16][17] Since the 1990s, factory
streetfighters have been produced. [18] As with naked
bike and muscle bike (below), the name streetfighter
is used to help clarify the middle ground occupied by
designs that blend elements of both sport bikes and
standards...
