Brake control system (BC)The brake control system regulates hy-
draulic brake pressure for the front and
rear wheels independently when the
respective brake lever or brake pedal is
applied and wheel lock is detected.
There are two settings, BC1 and BC2.
BC1 is standard ABS, which adjusts
brake pressure based on vehicle
speed and wheel speed data. BC1 is
designed to engage and maximize
braking when the vehicle is upright.
Regarding ABS, operate the brakes as
you would conventional brakes. When
the brake control system engages, a
pulsating sensation may be felt at the
brake lever or brake pedal as the hy-
draulic unit rapidly applies and reduces
brake pressure. In this situation, conti-
nue to apply the brake lever and brake
pedal to allow the ABS to work—do
not “pump the brakes” as this will re-
duce braking effectiveness.
WARNING
EWA16051
Always keep a sufficient distance
from the vehicle ahead to match the
riding speed even with ABS.
The ABS performs best with
long braking distances.
 On certain surfaces, such as
rough or gravel roads, the brak-
ing distance may be longer with
the ABS than without.
BC2 incorporates standard ABS and in
addition regulates braking power when
cornering to suppress lateral wheel
slip.
WARNING
EWA20891
The brake control system is not a
substitute for the use of proper rid-
ing and braking techniques. The
brake control system cannot pre-
vent all loss of traction due to over-
braking from excessive speed, or
lateral wheel slip when braking on
slippery surfaces.The ABS hydraulic unit is monitored by
the ABS ECU, which will revert the sys-
tem to conventional braking if a mal-
function occurs.
TIPThe ABS performs a self-diagnosis test
when the vehicle is started and reach-
es a speed of 10 km/h (6 mi/h). During
this test, a clicking noise may be audi-
ble from the hydraulic control unit, and
a vibration may be felt at the brake le-
ver or pedal, but this is normal.NOTICE
ECA20100
Be careful not to damage the wheel
sensor or wheel sensor rotor; other-
wise, improper performance of the
ABS will result.1. Front wheel sensor rotor

Fuel tank capTo open the fuel tank cap
Open the fuel tank cap lock cover, in-
sert the key, and then turn it 1/4 turn
clockwise. The lock will be released
and the fuel tank cap can be opened.
To close the fuel tank cap
With the key still inserted, push down
the fuel tank cap. Turn the key 1/4 turn
counterclockwise, remove it, and then
close the lock cover.
TIPThe fuel tank cap cannot be closed un-
less the key is in the lock. In addition,
the key cannot be removed if the cap is
not properly closed and locked.
WARNING
EWA11092
Make sure that the fuel tank cap is
properly closed after filling fuel.
Leaking fuel is a fire hazard.

FuelMake sure there is sufficient gasoline in
the tank.
WARNING
EWA10882
Gasoline and gasoline vapors are
extremely flammable. To avoid fires
and explosions and to reduce the
risk of injury when refueling, follow
these instructions.1. Before refueling, turn off the en-gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. When refueling, be sure to insert the
pump nozzle into the fuel tank filler
hole. Stop filling when the fuel
reaches the bottom of the filler
tube. Because fuel expands when
it heats up, heat from the engine or
the sun can cause fuel to spill out
of the fuel tank. 3. Wipe up any spilled fuel immedi-
ately. NOTICE: Immediately
wipe off spilled fuel with a clean,
dry, soft cloth, since fuel may
deteriorate painted surfaces or
plastic parts.
[ECA10072]
4. Be sure to securely close the fuel tank cap.
WARNING
EWA15152
Gasoline is poisonous and can cau-
se injury or death. Handle gasoline
with care. Never siphon gasoline by
mouth. If you should swallow some
gasoline or inhale a lot of gasoline
vapor, or get some gasoline in your
eyes, see your doctor immediately. If gasoline spills on your skin, wash
with soap and water. If gasoline
spills on your clothing, change your
clothes.
EAU86072
Your Yamaha engine was designed to
use unleaded gasoline with a research
octane number of 95 or higher. If en-
gine knocking or pinging occurs, use a
gasoline of a different brand or higher
octane rating.

Catalytic converterThe exhaust system contains catalytic
converter(s) to reduce harmful exhaust
emissions.
WARNING
EWA10863
The exhaust system is hot after op-
eration. To prevent a fire hazard or
burns: Do not park the vehicle near
possible fire hazards such as
grass or other materials that
easily burn.
 Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
 Make sure that the exhaust sys-
tem has cooled down before
doing any maintenance work.
 Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up of
heat.

adjuster in direction (a), the 0 click
position and the 1 click position
may be the same.
 When turning the damping force
adjuster in direction (b), it may
click beyond the stated specifica-
tions, however such adjustments
are ineffective and may damage

This model is equipped with ÖHLINS
electronic racing suspension with gas
reservoir. The compression and re-
bound damping forces are electroni-
cally adjusted (see ERS on page 4-20).

ed.
WARNING
EWA20900
The front fork legs contain highly
pressurized nitrogen gas. Read and
understand the following informa-
tion before handling the front fork
legs.
 Do not subject the axle brackets
to open flame or other heat
source. This may cause the
units to explode due to exces-
sive gas pressure.
 Do not attempt to open the gas
cylinder assemblies.
 Do not deform or damage the
cylinders in any way. Cylinder
damage will result in poor
damping performance.
 Do not dispose of a damaged or
worn-out front fork leg yourself.
Take the front fork leg to a
Yamaha dealer for disposal.Spring preload 1. Turn the vehicle off.
2. Slide the rubber cover back at each coupler. 3. Remove the coupler on each front

Adjusting the shock absorber
assembly
WARNING
EWA10222
This shock absorber assembly con-
tains highly pressurized nitrogen
gas. Read and understand the fol-
lowing information before handling
the shock absorber assembly.
 Do not tamper with or attempt
to open the cylinder assembly.
 Do not subject the shock ab-
sorber assembly to an open
flame or other high heat source.
This may cause the unit to ex-
plode due to excessive gas
pressure.
 Do not deform or damage the
cylinder in any way. Cylinder
damage will result in poor
damping performance.
 Do not dispose of a damaged or
worn-out shock absorber as-
sembly yourself. Take the shock
absorber assembly to a Yamaha
dealer for any service.
YZF-R1
This model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, fast compres-
sion damping force, and slow
compression damping force can be
adjusted.NOTICE

To avoid damaging the mechanism,
do not attempt to turn beyond the
maximum or minimum settings.Spring preload
1. Loosen the locknut.
2. Turn the adjusting nut in direction (a) to increase the spring preload.
Turn the adjusting nut in direction
(b) to decrease the spring preload.
The spring preload setting is de-
termined by measuring distance
A. The longer distance A is, the
higher the spring preload; the
shorter distance A is, the lower the
spring preload. Use the special wrench in-
cluded in the tool kit to make
the adjustment.

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 con-
trols exhaust flow within the exhaust
chamber.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.

SidestandThe sidestand is located on the left
side of the frame. Raise the sidestand
or lower it with your foot while holding
the vehicle upright.TIPThe built-in sidestand switch is part of
the ignition circuit cut-off system,
which cuts the ignition in certain situa-
tions. (See the following section for an
explanation of the ignition circuit cut-
off system.)
WARNING
EWA10242
The vehicle must not be ridden with
the sidestand down, or if the side-
stand cannot be properly moved up (or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
