controls – such as higher foot pegs and

lower handlebars – to ensure optimised

rider positioning.

Superbikes also feature a plethora of

advanced and upgraded components

and technologies. In terms of braking,

thicker high-grade brake pads are used

in conjunction with larger iron, carbon

or ceramic-matrix disc brakes, which in

turn are fi tted with multi-piston

callipers clamped onto oversized vented

rotors. Suspension systems are

multi-adjustable at both the front and

rear – which allows adjustment for road

conditions and riding st yle – and wheel

forks are fi tted with independent left

and right cushioning to improve

damping performance (the reduction of

friction and oscillation at high velocity).

Engine crankshafts (the part of the

engine that translates the reciprocating

linear piston motion of the power stroke

into rotational motion) are also custom

built to ensure a smoother combustion

process. On top of this, each superbike’s

transmission is modifi ed to use with

Why do they have such explosive performance?

Almost all modern superbikes have

extensive liquid-cooling systems

and smart composite materials to

improve cooling and heat transfer

while in operation. Further, many

components are made from

lightweight aluminium alloys and

are covered with chrome-nitride

coatings to reduce friction.

Combustion efficiency is achieved

by employing iridium spark plugs in

conjunction with refined fuel

injection systems. In addition,

advanced engine firing systems are

used to improve the smoothness of

energy transfer to the road, as

demonstrated in the crossplane

crankshaft installed on the Yamaha

YZF-R1. Here the YZF-R1’s crankshaft

is designed to fire unevenly in order

to produce combustion rather then

inertial torque. This improves

power, smoothness and rider feel

when riding at speed.

Engine

The Hayabusa GSX1300R

is equipped with a 1,340cc,

in-line, liquid-cooled engine

with 16 valves.

Transmission

The GSX1300R is kitted out with an

optimised six-speed transmission.

Oil is automatically sprayed to the

4th, 5th and 6th gears to reduce

wear and mechanical noise.

Instrumentation

The instrumentation features four

analogue meters for the bike’s

speedometer, tachometer, fuel gauge

and water temperature.

Chassis

Made entirely from aluminium, the frame is

designed to maximise strength while

minimising weight. This is evident in the bike’s

bridged aluminium swingarm.

Brakes

Radial-mount front brake callipers

allow the GSX1300R to be fitted with

smaller 310mm front brake rotors to

reduce unsprung weight and improve

handling. A single piston rear brake

calliper works in conjunction with a

260mm rear brake disc.
