EAU66297
YRC (Yamaha Ride Control)Yamaha Ride Control is a system that
incorporates numerous sensors and
controls to support an improved riding
experience. The vehicle senses and
can react to forces along the longitudi-
nal (front-to-back), lateral (left-to-right),
and vertical (up-and-down) axes. Lean
angle and G-force accelerations are
also detected. This information is pro-
cessed multiple times a second and the
related physical systems are automati-
cally adjusted as necessary. The fol-
lowing functions represent individual
YRC items which can be turned on/off
or adjusted to suit various riders and
riding conditions. For setting details,
see pages 4-11 and 4-16.
WARNING
EWA18221
The Yamaha Ride Control (YRC) sys-
tem is not a substitute for the use of
proper riding techniques or the ex-
pertise of the operator. This system
cannot prevent loss of control
caused by rider errors such as trav-
eling faster than warranted by road
and traffic condition s, including lossof traction due to excessive speed
when entering turns, when acceler-
ating hard at a sharp lean angle, or
while braking, and it cannot prevent
front wheel slip or front wheel lift. As
with any motorcycle, always ride
within in your limits, be aware of sur-
rounding conditions, and ride ap-
propriately for those conditions.
Become thoroughly familiar with the
way the motorcycle handles with
various YRC settings before at-
tempting more advanced maneu-
vers.
PWR
The power delivery mode system con-
sists of four different control maps
which regulate throttle valve opening in
relation to the degree of throttle grip op-
eration, thus providing you with a selec-
tion of modes to fit your preferences
and the riding environment.
TCS
The traction control system helps main-
tain traction when accelerating. If sen-
sors detect that the rear wheel is
starting to slip (uncontrolled spinning),
the traction control system assists by
regulating engine power as needed un-
til traction is restored. The traction con-
trol system indicator/warning light
flashes to let the rider know that traction
control has engaged.

12 “YRC Setting”
This module allows you to customize
the four YRC modes MODE-A,
MODE-B, MODE-C, MODE-D by ad-
justing the setting levels (or on/off sta-
tus as applicable) of YRC items PWR,
TCS, SCS, LCS, QSS, and LIF. For
YZF-R1M, you can select the ERS
mode to be associated with each YRC
mode, and also adjust the setting levels
of the ERS modes.
TIP
TCS has 9 setting levels and ERS
has 6 modes.

Whenever there are more selec-
tions (setting levels or modes)
available than can be shown on
the screen at one time, a scroll bar
will appear to notify you that addi-
tional selections are available byscrolling.
PWR
Select PWR-1 for the most aggressive
throttle response, PWR-2 and PWR-3
for smoother throttle grip/engine re-
sponse, and use PWR-4 for rainy days
or whenever less engine power is desir- able.
TCS
This model uses a variable traction
control system. For each setting level,
the further the vehicle is leaned over,
the greater the amount of traction con-
trol (system intervention) is applied.
There are 9 setting levels available.
Setting level 1 applies the least amount
of overall system intervention, while
setting level 9 applies the greatest
amount of overall traction control.
TIP
TCS can only be turned on or off
via the main screen using the
mode switch.

When TCS has been turned off,
TCS, SCS, LCS, and LIF will be
set to OFF and cannot be adjust-
ed. When TCS is turned on again,
these related-traction control func-
tions will return to their previoussetting levels.
SCS
SCS can be set to OFF, 1, 2, and 3.
OFF turns the slide control system off,

NOTICE
ECA11401
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,as well as to the exhaust system.
TIP
This mark identifies the recom-
mended fuel for this vehicle as
specified by European regulation
(EN228).

Check that gasoline nozzle has thesame identifier when fueling.
Your Yamaha engine has been de-
signed to use premium unleaded gaso-
line with a research octane number of
95 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different
brand. Use of unleaded fuel will extend
spark plug life and reduce maintenance
costs.
Gasohol
There are two types of gasohol: gaso- hol containing ethanol and that contain-
ing methanol. Gasohol containing
ethanol can be used if the ethanol con-
tent does not exceed 10% (E10). Gas-
ohol containing methanol is not
recommended by Yamaha because it
can cause damage to the fuel system
or vehicle performance problems.
Recommended fuel:
Premium unleaded gasoline (Gaso-
hol [E10] acceptable)
Fuel tank capacity: 17 L (4.5 US gal, 3.7 Imp.gal)
Fuel reserve amount (when the fuel
level warning light comes on):
3.0 L (0.79 US gal, 0.66 Imp.gal)

EXUP systemThis model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that controls
exhaust flow within the exhaust cham-
ber.NOTICE
ECA15611
The EXUP system has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-mance of or damage to the engine.

Items marked with an asterisk should be performed by your Yamaha dealer because these items require special tools,
data, and technical skills.

From 50000 km (30000 mi), repeat the maintenance intervals starting from 10000 km (6000 mi).

The annual checks must be performed every year, except if a distance-based maintenance is performed in-
stead.

Valve clearanceThe valves are an important engine
component, and since valve clearance
changes with use, they must be
checked and adjusted at the intervals
specified in the periodic maintenance
chart. Unadjusted valves can result in
improper air-fuel mixture, engine noise,
and eventually engine damage. To pre-
vent this from occurring, have your
Yamaha dealer check and adjust the
valve clearance at regular intervals.TIPThis service must be performed whenthe engine is cold.
EAU70961
TiresTires are the only contact between the
vehicle and the road. Safety in all con-
ditions of riding depends on a relatively
small area of road contact. Therefore, it
is essential to maintain the tires in good
condition at all times and replace them
at the appropriate time with the speci-
fied tires.
Tire air pressure
The tire air pressure should be checked
and, if necessary, adjusted before each
ride.
WARNING
EWA18370

Operation of this vehicle with
improper tire air pressure may
cause severe injury or death
from loss of control.

The tire air pressure must be
checked and adjusted on cold
tires (i.e., when the temperature
of the tires equals the ambienttemperature).
WARNING
EWA10512
Never overload your vehicle. Opera-
tion of an overloaded vehicle couldcause an accident.
Tire inspection
Cold tire air pressure: Front:250 kPa (2.50 kgf/cm
2, 36 psi)
Rear:
290 kPa (2.90 kgf/cm2, 42 psi)
Maximum load*: 187 kg (412 lb)

12 The tires should be checked before
each ride. If the center tread depth
reaches the specified limit, if the tire
has a nail or glass fragments in it, or if
the sidewall is cracked, have a Yamaha
dealer replace the tire immediately.
TIPThe tire tread depth limits may differ
from country to country. Always complywith the local regulations.
WARNING
EWA10472

Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the vehi-
cle with excessively worn tires
decreases riding stability and
can lead to loss of control.

The replacement of all wheel
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience to do so.

Ride at moderate speeds after
changing a tire since the tire
surface must first be “broken
in” for it to develop its optimalcharacteristics.
Tire information
This model is equipped with tubeless
tires and tire air valves.
Tires age, even if they have not been
used or have only been used occasion-
ally. Cracking of the tread and sidewall
rubber, sometimes accompanied by
carcass deformation, is an evidence of
ageing. Old and aged tires should be checked by tire specialists to ascertain
their suitability for further use.
WARNING
EWA10482

The front and rear tires should
be of the same make and de-
sign, otherwise the handling
characteristics of the motorcy-
cle may be different, which
could lead to an accident.

Always make sure that the valve
caps are securely installed to
prevent air pressure leakage.

Use only the tire valves and
valve cores listed below to
avoid tire deflation during ahigh-speed ride.
After extensive tests, only the tires list-
ed below are approved for this model
by Yamaha.
Minimum tire tread depth (front and
rear): 1.6 mm (0.06 in)
1. Tire air valve
2. Tire air valve core
3. Tire air valve cap with seal
