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.

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

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

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

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
• 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.
