Means of sport bikes..

A sport bike , aka "sportbike" and
"sportsbike", is a motorcycle
optimized for speed, acceleration,
braking, and cornering on paved
roads, [1][2][3][4] typically at the
expense of comfort and fuel
economy by comparison with
more standard motorcycles .

The emphasis of a sport bike
being on speed, acceleration,
braking, and maneuverability,
there are certain design elements.
that most motorcycles of this
type will share.

Rider ergonomics..
This generally means higher foot pegs that move the legs closer to the body and moreof a reach to a lower
set of hand controls, such as clip
on handlebars, which positions
the body and weight forward and
over the tank. [4][6] Sport bikes
have comparatively high-
performance engines resting
inside a lightweight frame.[6]
High tech and expensive
materials are often used on sport
bikes to reduce weight. [6]
Braking systems combine higher
performance brake pads and disc
brakes with multi-piston calipers
that clamp onto oversized
vented rotors. Suspension
systems are advanced in terms
of adjustments and materials for
increased stability and durability.
Front and rear tires are larger
and wider than tires found on
other types of motorcycles to
allow higher cornering speeds
and greater lean angles. Fairings
may or may not be used on a
sport bike; when used, fairings
are shaped to reduce
aerodynamic drag as much as
possible and provide wind
protection for the rider.[6]
The combination of rider position,
location of the engine and other
heavy components, and the
motorcycle's geometry help
maintain structural integrity and
chassis rigidity, and determine
how it will behave under
acceleration, braking, and
cornering. Correct front-to-rear
weight distribution is of particular
importance to the handling of
sport bikes, and the changing
position of the rider's body
dynamically changes the
handling of the motorcycle. [15]
Because of the complexity of
modeling all the possible
movements of different sized
riders, to approach perfect tuning
of a motorcycle's weight
distribution and suspension is
often only possible by having a
bike customized or at least
adjusted to fit a specific rider.[15]
Generally, road racing style sport
bikes have shorter wheelbases
than those intended for more
comfortable touring, and the
current trend in sport bike design
is towards shorter wheelbases,
giving quicker turning at the
expense of a greater tendency
for unintentional wheelies and
stoppies under hard acceleration
and braking, respectively. [15][16]
