Focus of Improvement

• Thoroughly review the model’s

original “The Top Performer”concept

• Achieve a tangible evolution in

each of the basic performanceaspects of acceleration,

cornering & braking

• Further improve circuit

performance



Achievements

• Engine

– Better low & mid-range torque curve

– Improved throttle response

– Improved fuel economy by 8%*

• Chassis – 2kg (4.4lbs) weight reduction

– Improved agility & handling

– Enhanced braking performance

• Styling

– Refinements with extra accents

*Fuel economy was measured by Suzuki in the Worldwide Motorcycle Test Cycle (WMTC)



Engine Design Targets

Weight reduction

Improve throttle response

Improve fuel economy

Boost low-to-mid rpm range



Exhaust

• New single muffler design – Change from twin to single exhaust

contributes to weight reduction, better

centralization of mass and better power

feeling.

– The 4-2-1 exhaust pipe is made of

stainless steel, and a thinner materialused for lightness. Muffler body is made

of titanium.

– The under-engine chamber was

eliminated and pipe length optimized to

increase the low- to mid-range power

output that is essential on the racetrack.

– The catalyser increases the number ofcells over the current model



• Newly designed pistons

– Finite-element-method (FEM) & fatigue

analysis techniques honed in developmentof MotoGP racebike engines was used to

make the pistons 11% lighter

– The piston-pin bosses are narrower. The

piston skirts are newly shape-optimized,

with asymmetry between the intake and

exhaust sides

• Increased compression ratio from12.8:1 to 12.9:1

– Higher compression ratio achieves better

combustion efficiency

Crankcase

• Newly designed crankcase ventilation holes

– Pentagonal cut-out in crankcase reduces pumping loss, contributes to

low and mid-range torque and fuel economy.

2012 model 2011 model



Camshafts

• Changes to the cam profiles – In conjunction with the change to the new single muffler design,

advanced technology from MotoGP competition was applied in the

exhaust cam profile

– More emphasis on high-rev range output - higher racing potential

without compromising low and mid range

– The duration of valve overlap was shortened when the intake andexhaust valves are both open



Camshafts

Boost low-to-mid rpm range

Improve throttle response



Valves

• Redesigned valve tappet – Thinner material for the tappet skirts means a weight

saving of 2.5 grams per tappet

– Reduced weight enables match with cam profile change



Electrical

• Optimized ECU programming

– Refined ECU program to match with engine changes.

• NGK CR9EIA-9 iridium spark plugs

– The iridium plugs are efficient and they help realize fine control over

engine settings. Carry-over from the current model.

Throttle Body

• Suzuki Dual Throttle Valve (SDTV) system

– Each of two throttle bodies feeds two cylinders, each carries two

ultra-fine-atomization, 12-hole injectors; and two butterfly valves in

each throttle-body barrel produce precise combustion control

– Result is a system that realizes the benefits of near-linear throttle

response and torque output across the entire rpm range.

– This system is carried over from the current model



Clutch

• Back-torque-limiting clutch

– Back-torque limiter offers smoother downshifting operation

– Stabilizes the chassis when downshifting

– Carried over from the current model





Suzuki Pulsed Secondary-AIR (PAIR)

• Suzuki pulsed secondary-AIR (PAIR) – Injection system injects fresh air from the air cleaner box directly into

the exhaust ports where it promotes the ignition of unburned

hydrocarbons (HC) to reduce carbon monoxide (CO) emissions

– PAIR control solenoid valve, which is controlled by the ECM in

accordance with throttle position and engine rpm.

– This system is carried over from the current model



Steering Damper

• Steering Damper

– Electronically controlledsteering damper contributes to

handling stability and a more

alert and agile feel

– Increasing the damping force athigher speeds and reducing it at

lower speeds

– The damper is carried over from

the current model



Suzuki Drive Mode Selector (S-DMS)

• S-DMS

– Allows selection of one of three engine

power delivery modes to suit the rider’s

personal preferences and riding

conditions

– The mode selection switch is mounted

on the left handlebar and its two

buttons can be easily operated by the

thumb and index finger – The S-DMS system is carried over

from the current model



S-DMS

Engine power-delivery characteristics

A-mode A-mode provides sharp throttle response throughout

the throttle’s opening range to obtain maximumengine power.

B-mode B-mode provides softer throttle response than A-modeup to the throttle’s mid-open range.

C-mode C-mode reduces engine power to provide soft throttleresponse throughout the throttle’s opening range.



Chassis Design Target

Improve weight distribution

Enhance Brake performance

Weight reduction



Chassis

• The chassis retains the winning agility & running performance

– Twin-spar frame welded together using five cast aluminium-alloy sections, and

an aluminium-alloy swingarm that’s welded together using just three castings

and is arched to allow the muffler to be tucked in tightly

– The chassis also continues to feature the shortest wheelbase in its class.

(As of January 2012)

Brakes

• New Brembo monobloc front brake calipers

– The monobloc calipers are lighter and more rigid than

conventional bolt-together calipers

– Improved braking performance & rider feedback

• New Sunstar Engineering front brake discs

– Made of heat-resistant stainless steel and adopted as aworld first by Suzuki

– Thickness reduced from 5.5mm to 5.0mm reducing

weight while fully retaining the thermal-warping and

cracking resistance



Brakes

• Rear Brake – The rear brake system uses the same single-piston caliper from NISSIN

as the current model. The compact design contributes to a reduction ofunsprung weight.



Suspension

• Big Piston Front-fork (BPF) with tuned settings – New enhancements include a reduction of 7mm in overall length,

a reduction of 5mm in stroke

– Softer suspension settings accommodate the bike’s lower weight

and the shift in center of gravity that resulted from the switch from

twin mufflers to one

– Softer setting at beginning enables better traction feeling

improving shock absorption early in the stroke, thereby improving

grip



Suspension

• Rear suspension

– The rear suspension with fully adjustable spring preload and rebound

and compression damping force is carried over from the current model.
