New-generation YZF-R1: Highly purified excitement
The radical and innovative new 2009 model YZF-R1
represents the most significant development in engine
and chassis technology ever seen in the 11-year history
of this legendary motorcycle.
Since the original YZF-R1 was released into an awe-struck
marketplace, Yamaha’s flagship 1,000cc model
has established a reputation as being one of the most
innovative and exciting motorcycles in the large-capacity
supersport class. For 2009 that outstanding reputation
is sure to be reinforced more than ever before!
Featuring an all-new 998cc engine whose design, feel
and character has been influenced by our championship
winning M1, the new high-tech R1 powerplant is closely
linked to our MotoGP bike. Indeed, in its long and
illustrious history, the R1 engine has never benefited
from so much MotoGP developed technology as the 2009
model.
In addition, the completely redesigned aluminium
Deltabox chassis and aggressive new styling, give
the new-generation YZF-R1 a radical new look and bring
innovative technology to the class. In the same way
that the original YZF-R1 threw the rule book out of
the window, this revolutionary new model sets a new
benchmark for the super-competitive 1,000cc supersport
category.
Crossplane crankshaft engine for purer torque
output
Rather than look exclusively to additional electronic
aids to further enhance the new YZF-R1’s performance
and controllability, Yamaha’s engineers have
opted for a mechanical solution.
The defining and most influential feature of the
new YZF-R1 is the use of an innovative new 998cc engine
which has been developed from our winning YZR-M1 MotoGP
design. Undoubtedly the single most significant piece
of technology to be seen on this compact new high-performance
engine is its race-developed crossplane crankshaft,
which delivers outstandingly pure torque characteristics
and high levels of traction. Indeed, the new engine’s
linear and controllable torque characteristics are
the very essence of this radical new generation YZF-R1.
Uneven firing interval for new levels of feel
and traction
The new engine’s uneven 270° - 180°
- 90° - 180° firing interval creates a whole
new feel to the inline 4-cylinder engine, giving the
new YZF-R1 rider a more precise and immediate feeling
of control over the torque output levels. In addition,
the new engine’s linear torque delivery gives
rise to a confidence-inspiring sensation that makes
each throttle input, however subtle, feel as though
it is transmitted directly to the rear tyre.
The result of this rider-responsive torque is an
enormously capable 1,000cc supersport motorcycle that
is designed to deliver previously unattainable levels
of traction for unrivalled cornering performance.
To accentuate the performance gains of the new crossplane
crankshaft engine, we have also developed a new short-wheelbase
aluminium Deltabox chassis and optimized the front
and rear suspension systems. And the radical and aggressive
new styling emphasises the new YZF-R1’s concentration
of mass and dense compactness.
2009 YZF-R1. Pure Yamaha innovation.
Engine
Newly-designed inline 4-cylinder engine
with crossplane crankshaft
This remarkable new 998cc liquid-cooled inline 4-cylinder
4-valve engine features bore x stroke dimensions of
78.0 mm x 52.2 mm, giving an extremely short stroke
layout, together with the largest bore dimensions
ever used on a Yamaha 1,000cc supersport engine. In
association with the short stroke and big bore, a
high compression ratio of 12.7:1 is featured, which
contributes to the new engine’s impressive power
output of 133.9 kW (182 PS) at 12,500 rpm, and a torque
output of 115.5 Nm (11.8 kg-m) at 10,000 rpm with
natural aspiration.
* In France, in accordance with the enforced regulations,
the horsepower is limited. The YZF-R1 provides 78.1
kW (106 PS) at 10,000 rpm and a torque of 90.3 Nm
(9.2 kg-m) at 7,000 rpm.
Crossplane crankshaft with uneven firing
interval for linear throttle control
Undoubtedly the most significant change for 2009
is the use of an all-new crossplane crankshaft which
is based on the advanced race-bred technology that
was originally developed for the Yamaha YZR-M1 MotoGP
racing machine. This new crossplane crankshaft has
been introduced in order to enable the new engine
to produce more linear torque characteristics, together
with more accurate and linear throttle control.
The new engine’s linear power characteristics
deliver a 1:1 relationship between the rider’s
throttle input and the engine’s output to the
rear tyre, and it is this crucial aspect of the new
bike’s character that allows the rider to experience
a new of level of cornering performance, together
with outstanding traction when entering the mid-section
of a corner, and also when accelerating out of a bend.
Another feature of the crossplane crankshaft with
uneven firing interval is the very special exhaust
note that this layout produces, and the new 2009 YZF-R1
engine note has much in common with the YZR-M1 racing
machine.
The search for pure torque
When an engine produces torque, it is actually producing
what our engineers refer to as “composite torque”,
which is a combination of the torque produced by combustion,
and the inertial torque resulting from the revolution
of the engine’s crankshaft.
Although the level of combustion torque is both proportionate
to, and also a direct result of the rider’s
throttle input, the inertial torque is produced in
direct relation to the changes in inertial force caused
by the engine’s revolutions – and so this
element of the composite torque is not under the direct
and immediate control of the rider. The composite
torque level varies throughout the engine’s
rpm range, regardless of the rider’s throttle
input, and the unpredictable nature of this composite
torque means that the rider cannot select precisely
and immediately the torque level that they desire
at any given moment.
Therefore, in order to be able to offer more linear
control to the rider, it is necessary to create an
engine where the inertial torque can be minimized,
and the composite torque optimized.
Uneven 270º - 180º - 90º -
180º firing interval
One of the most effective means of achieving optimal
composite torque in a 4-cylinder engine is the adoption
of a crossplane crankshaft with the crankpins positioned
to give a firing interval of 270º - 180º
- 90º - 180º, as opposed to the 180º
- 180º - 180º - 180º firing interval
of a conventional 4-cylinder engine.
So, while a conventional 4-cylinder engine sees the
four pistons and con rods effectively move up and
down in the cylinders as two pairs (i.e. on the 2008
YZF-R1 the two outermost pistons and con rods move
together, as do the two innermost pistons and con
rods), each piston and con rod in the new crossplane
crankshaft has its own individual and separate movement.
The result is that the inertial torque created by
the reciprocating mass in the new YZF-R1 engine is
minimized, while the asymmetric firing sequence achieves
a strong pulse at low to mid rpm range, together with
excellent linearity across the whole rpm range.
In order to further optimize the combustion forces
in the new asymmetric motor, the electronic mapping
for the fuel injection system provides separate fuel
injection and ignition timing for each cylinder, and
this results in highly linear torque characteristics
that would not have been achievable on a conventional
engine with a standard crankshaft and 180º firing
sequence.
And for smoother running the YZF-R1’s new engine
is also fitted with a primary coupling balancer which
reduces the vibration produced by the asymmetric crankpin
layout.
Previously the crossplane crankshaft has only been
used on competition machinery due to the complex-shaped
crankpins and crankshaft parts, as well as other factors
including fluctuations in combustion torque pressure
and levels of vibration. For these reasons this asymmetric
engine layout has never been used before on mass-produced
4-cylinder supersport motorcycles, and its use on
the new YZF-R1 represents one of the most significant
technical innovations ever witnessed in the 1,000cc
supersport category.
Newly-developed forged aluminium pistons
The new YZF-R1 is equipped with lightweight forged
aluminium pistons which have been manufactured using
the same process as the 2008 YZF-R1. During the special
forging process, the aluminium alloy is not actually
melted, but is only heated to the temperature where
it can be shaped under pressure in the forge. This
system allows the aluminium to retain more of the
original strength of the metallurgic matrix, which
enables our engineers to specify a lighter piston
design, thereby reducing reciprocating weight and
enhancing throttle response.
Closed-deck ceramic-composite plated cylinder
The new lightweight ceramic-composite plated cylinder
provides excellent heat dissipation together with
an outstanding rigidity balance. This new short-stroke
cylinder features a closed-deck design in which the
coolant passages do not pass from the cylinder into
the cylinder head, and this makes for high levels
of reliability in this type of high compression inline
4-cylinder engine. The new short-stroke engine also
benefits from shorter cylinder stud bolts which gives
a weight reduction, and at the same time helps reduce
overall engine height to give compact overall dimensions.
Fracture split (FS) carburized con rods
The new 2009 model YZF-R1 is equipped with fracture-split
(FS) carburized con rods, a system that has been used
successfully by Yamaha since the 2004 model YZF-R1.
The two halves of each fracture-spit big end ring
are re-assembled along the same fracture lines, and
this makes for a stronger and more perfectly round
big end, giving outstanding performance and reliability.
Optimised large-diameter crank journal and
flywheel mass
The all-new YZF-R1 engine design is equipped with
a larger 36 mm crank journal (compared to 32 mm diameter
on the 2008 model YZF-R1) which is designed to handle
the new power and torque characteristics of the crossplane
crankshaft.
YCC-I (Yamaha Chip Controlled Intake)
The YCC-I system features electronically-controlled
intake funnels whose length can be varied to suit
the prevailing engine speed in order to provide good
intake pulsation.
At low to mid engine speeds the long and short funnels
operate as a single connected unit, but when the engine
speed exceeds 9,400 rpm the YCC-I on the new YZF-R1
engine automatically separates the lower funnel and
upper funnel by means of an electronically-controlled
servomotor. By varying intake length to suit engine
rpm, the YCC-I system enables the new YZF-R1 engine
to operate more effectively across the rpm band, and
the funnel separation process is so smooth that the
rider is unaware it has happened.
YCC-T (Yamaha Chip Controlled Throttle)
The advanced YCC-T electronic throttle system delivers
outstanding controllability at all speeds, and helps
to prevent any hesitation caused by an excessive fuel/air
supply when the throttle is opened suddenly. The system
adjusts the throttle valve opening via a servomotor
at intervals of 1/100th of a second. By constantly
calculating and adjusting the optimal throttle opening
and intake air volume to match the prevailing engine
running conditions, the YCC-T consistently ensures
that the new YZF-R1 engine produces an optimum drive
torque curve – and the ignition timing is mapped
separately for each cylinder in order to ensure efficient
combustion processes.
Fuel injection system with secondary injector
The YCC-T operates a highly-efficient twin injector
type fuel injection system which is designed to deliver
outstanding throttle response and remarkable performance
at all riding speeds.
This twin injector system features a main injector
together with a secondary injector, which is situated
at the upper edge of the funnel. The secondary injector
comes into operation in the engine’s mid to
high-speed range to complement the main injector,
and this design ensures remarkable response and outstanding
acceleration and performance.
D-mode Map
For the first time on a Yamaha supersport model,
the new YZF-R1 is equipped with a D-mode Map which
works in association with the YCC-T (Yamaha Chip Controlled
Throttle) and allows the rider to select a performance
profile to match their requirements.
The D-mode Map consist of three modes which are:
Standard mode; A mode; and B mode; and the rider can
choose which mode is best suited to the prevailing
riding conditions by operating a switch on the handlebars.
Standard mode is mapped to give optimum all-round
performance, while the A mode delivers sharper engine
response, and the B mode gives a gentler response
to the rider’s throttle inputs.
Redesigned forced air intake
The YZF-R1’s redesigned forced air intake
system utilises the natural airflow to increase the
pressure of the air in the airbox, and this ensures
increased levels of power at higher speeds for outstanding
performance. This system takes air in through the
front cowl, and channels it via the left and right
sides of the new frame, directly into the airbox.
For 2009 the YZF-R1’s forced air intake system
incorporates special new side branches which reduce
intake noise.
Slipper clutch
For even more stable handling performance when decelerating
during quick downshifting, the 2009 YZF-R1 is equipped
with a slipper clutch. This clutch features a mechanism
that adjusts clutch spring load when excessive torque
is transferred from the rear wheel to the crank when
the rider changes down through the transmission. By
controlling excessive engine braking forces, this
system enhances overall controllability.
4-2-1-2 exhaust and twin up-slanted mufflers
In order to ensure an effective exhaust pulsation
to complement the new engine’s crossplane crankshaft,
an all-new exhaust system is fitted, in which the
exhaust pipes for the 1st and 4th cylinders and for
the 2nd and 3rd cylinders are brought together in
a 4-2-1-2 layout.
This high performance system features a 3-way catalyser
positioned at the point where the four exhaust pipes
meet, and outstanding environmental performance is
ensured by an O2 sensor linked to the ECU which constantly
adjusts the fuel/air mix in order to minimize harmful
emissions.
The stylish triangular-shaped mufflers emit a sharp,
gutsy exhaust note which complements the unique pulse
created by the asymmetric firing sequence of the new
crossplane crankshaft. The triangular design also
contributes to the tighter and more compact body design
of the all-new YZF-R1, while at the same time giving
the bike’s rear end a sharp new look.

Chassis
Newly designed aluminium Deltabox frame
The 2009 YZF-R1 runs with a completely new aluminium
Deltabox frame which has been designed to deliver
class-leading handling and cornering performance.
Particular attention has been paid to achieving a
handling character which allows the rider to fully
utilise the new linear torque characteristics and
high levels of traction delivered by the new crossplane
crankshaft engine.
With the exception of the internal forced air intake
ducts, the newly designed Deltabox frame is virtually
completely different to the 2008 design, and as well
as featuring a new shape with different dimensions,
the type of aluminium used and the frame’s overall
rigidity balance are also changed for 2009.
The new frame uses a combination of different types
of aluminium to achieve the desired balance of rigidity.
Gravity cast parts are used for the head pipe as well
as the engine mount assemblies and the pivot support
assembly, while the outside tank rails are made from
CF die-cast aluminium which allows the use of much
thinner walls. Parts for the inner tank rail are made
from extruded aluminium.
Idealised balance of rigidity
By using a combination of lightweight parts with
different characteristics, Yamaha’s engineers
have succeeded in creating a new Deltabox frame which
delivers an idealised balance of rigidity. For 2009,
the new YZF-R1’s lateral rigidity has been adjusted,
and as well as enhancing high speed stability, this
feature also helps improve overall handling performance,
particularly in terms of enabling effective traction
when exiting a curve.
The engine is a stressed member of the frame, and
the engine mounts are rigid types, with two on the
upper crankcase and two on the lower crankcase, and
two at the right and left ends of the cylinder head.
The new frame uses extremely strong cast parts at
the head pipe, swingarm pivot and engine mounts, while
the die-cast and extruded aluminium structures that
connect them are given a degree of forgiveness.
This unique combination of rigid and slightly less
rigid aluminium components are what give the new YZF-R1’s
Deltabox frame such a special character, which allows
the rider to explore the full potential of the machine’s
outstanding performance. In addition, the idealised
balance of rigidity on this innovative new frame also
enhances the very special direct torque feeling associated
with the exciting new crossplane crankshaft engine,
making the new YZF-R1 a truly unique riding experience.
Compact dimensions with lower centre of gravity
The new R1 engine is mounted 9 degrees more upright
than the 2008 model, and the cylinders are angled
forward at 31 degrees. Also, the engine mounting position
is 12 mm further forward in relation to the drive
axis than the 2008 YZF-R1, and this factor helps contribute
towards making the front wheel feel even more ‘stuck’
to the road. And with the new pivot position set a
few mm lower than previously, transfer of drive force
to the road surface is improved.
These factors, together with a new fuel tank design,
have come together to create a centre of gravity that
is slightly lower than the existing model, giving
optimized handling performance.
To illustrate the new bike’s compactness, an
imaginary triangle created by joining the front and
rear tyre contact patches with the centre of gravity
is smaller than on the 2008 YZF-R1. This compactness
makes for agile handling performance, and allows the
rider to make full use of the linear torque and high
traction when powering out of bends.
New-shape large-capacity fuel tank
Concentration of mass has been a significant feature
on all R-series supersport machines, and the new YZF-R1
takes the concept one step further with the fitment
of a newly-designed large-capacity fuel tank. The
press-formed shape was developed using 3-D simulation
analysis technology, and this has enabled our engineers
to create a larger, elongated fuel tank which sits
neatly within the new twin spar aluminium Deltabox
frame.
With a capacity of 18 litres, the shape and position
of the new fuel tank helps to improve concentration
of mass, and its central location helps to minimize
any variation in the new YZF-R1’s handling characteristics
as the amount of fuel in the tank decreases.
Magnesium rear frame
By using lightweight materials for those components
that are furthest from the machine’s centre
of balance, Yamaha’s engineers have been able
to enhance the YZF-R1’s concentration of mass
even further.
The magnesium rear frame made its debut on the 2008
model R6, and its use on the YZF-R1 takes the concentration
of mass on this new generation one litre supersport
machine to a new level.
New lighter swingarm with optimized rigidity
balance
The proven and successful combination of a short
wheelbase and long swingarm has been a feature on
all YZF-R1 models since the machine was launched.
A short wheelbase is associated with high levels of
agility and good manoeuvrability, while a long swingarm
which pivots close to the machine’s mid-way
point helps to deliver excellent stability during
acceleration. In addition, because the YZF-R1’s
long swingarm features a pivot point which is located
close to the axis of the final drive sprocket, rear
suspension squat during hard acceleration is minimized.
For 2009 the swingarm features a gravity-cast pivot
assembly, while the arm and end-piece is a single-unit
CF die-cast assembly. As a result of these changes,
the weight of the new swingarm is reduced, and the
rigidity balance has been optimized. This new swingarm
design helps to ensure responsive suspension action
and enhanced handling performance, especially when
the YZF-R1 rider is exiting fast from a corner.
2-way adjustable rear shock absorber and
bottom-link rear suspension
The adjustable rear shock absorber is equipped with
both low and high-speed compression damping adjustment,
allowing the rider to set the machine up to suit their
individual needs and different riding conditions.
The new bottom-link type suspension has been developed
to make the most effective use of the 120 mm stroke,
allowing the shock absorber to function efficiently
for a stable and smooth riding experience. Surface
feedback and damper response are all improved by the
use of a new pillow-type ball joint in the rear shock,
and for ease of adjustment, a hydraulic-type adjuster
is fitted.
Furthermore, bottom-link system enables to lower
the mounting location of the rear suspension, and
contributes to concentration of mass by setting the
fuel tank in the vacant space.
43mm front forks with independent left/right
side damping mechanisms
Like the 2008 model, the new YZF-R1 is equipped
with 43mm diameter front forks, but they are of a
completely different design to previous suspension
systems used on our R-series models.
For 2009 the rebound and compression damping functions
are separated, with the left fork equipped with the
compression damping valves, and the right fork equipped
with the rebound damping valves. This system offers
a number of advantages, including the simplification
of valve designs and oil flows, as well as minimizing
cavitations during successive strokes, and easier
adjustment.
Separating the damping functions has also enabled
our engineers to increase the diameter of the internal
cylinders which helps to stabilize various pressure
variances. This increase in cylinder diameter and
oil volume also ensures that there is always sufficient
oil available to deliver effective damping force for
even the smallest front suspension movements. Simpler,
more effective and easier to adjust, the new front
suspension system offers a clear advantage to the
YZF-R1 rider.
Lighter front brake discs with optimized
controllability
The R-series models are famous for their class-leading
braking performance, and the new YZF-R1’s compact
system has been designed to offer optimum levels of
braking power and controllability. The new front braking
system features 310 mm dual discs which are slowed
by dual six-piston calipers each containing four pads.
The lighter front discs reduce the inertial moment
around the axle, which reduces the gyro effect of
the front wheel to give lighter, more agile handling
and quicker directional changes.
In addition, the inner rotor has been redesigned to
give the desired amount of play to promote stable
braking force, and a newly designed front brake lever
offers improved operability and feel.
The rear brake features a 220mm diameter disc and
single-piston pin-slide caliper with an aluminium
piston, giving good braking operation and controllability.
Innovative new cooling system with active
air management
The cooling system on the new YZF-R1 features a
number of innovations, and a unique feature of this
advanced new design is the use of lightweight plastic
resin piping between the curved radiator and engine.
This durable plastic piping has been manufactured
using the ‘floating core’ method which
makes for a lightweight structure, and this is the
first time that this weight-saving technology has
been used on a production motorcycle*.
By locating the inner cowl as close as possible to
the engine, a passage has been created to channel
the air after it has passed through the radiator and
the two compact fans. At the same time, the negative
pressure created along the surface of the middle cowl
by the external airflow is actively used to draw this
hot air away from the machine, resulting in more effective
heat dissipation. Cooling efficiency is further improved
by the fact that sufficient space is available between
the inner cowl and the engine to allow the heated
air to escape with ease.
(*) As of Sept. 2008, based on Yamaha Motor study
Newly-designed rear tyre with 55% R rating
To match the new YZF-R1’s increased torque
feel and enhanced cornering performance, a new 190/55R-17
rear tyre is fitted. This slightly higher profile
tyre (compared to a 50% aspect ratio on the existing
YZF-R1) is designed to deliver a good grip feeling
especially when accelerating early from a curve.
New-look front end featuring headlights integrated
with air intakes
One of the most significant visual changes to the
new YZF-R1 is the completely redesigned front cowl
which features dual projector headlights integrated
with the air induction intakes. At the same time as
being instantly recognisable as an R-series design,
this radical new front end accentuates the image of
the YZF-R1 cutting through the air in forward motion,
and gives an even more intimidating and aggressive
supersport image.
The innovative new projector headlight design features
a solenoid coil type high/low beam switching mechanism,
the first time this system has been used on a production
motorcycle*. On low beam settings, a shade covers
part of the headlight, and when the high beam setting
is selected by the rider, the shade retracts to reveal
the whole of the projector headlight’s beam.
By using this new solenoid coil type high/low beam
switching mechanism, Yamaha’s designers have
been able to replace the 2008 model’s four projector
headlights (two high beam, two low beam) with two
units, allowing much greater freedom in the creation
of a much more compact and aggressive front cowl.
(*) As of Sept. 2008, based on Yamaha Motor study
New styling emphasises concentration of mass
The bold new bodywork and aggressive styling is
designed to convey the feeling of the new YZF-R1’s
concentration of mass and dense compactness, together
with a sense of minimalism and a front-rear concentration
of power.
At the same time the new-look side view is aimed
at drawing attention to the visual expression of the
immense traction and driving power of the YZF-R1’s
new crossplane crankshaft engine.
The newly-designed sculptured middle cowl offers excellent
aerodynamics for enhanced performance, as well as
high levels of wind protection. In addition, this
stylish cowl has also been designed to ensure that
hot air is removed from the engine compartment, and
its other role is to ensure that hot air is extracted
from the engine compartment to give excellent heat
dissipation.
New for 2009 is the option of a red frame, which
is featured exclusively on the white coloured YZF-R1.
This white/red colour scheme gives the bike an aggressive
look which complements the new bodywork and styling.
New instrumentation
To complement the completely restyled bodywork,
new instrumentation is fitted. The new multi-function
meter panel features a speedometer, rpm meter, coolant
temperature indicator, intake air temperature indicator,
two trip meters, trip fuel meter, clock, stopwatch,
shift timing light, gear position indicator and engine
mode indicator.
