Catalytic converterThis model is equipped with a catalytic
converter in the exhaust system.
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 do-
ing any maintenance work.
Do not allow the engine to idle
more than a few minutes. Long
idling can cause a build-up ofheat.
NOTICE
ECA10702
Use only unleaded gasoline. The use
of leaded gasoline will cause unre- pairable damage to the catalytic
converter.

Adjusting the front forkNOTICE
ECA22471
Use extra care to avoid scratch-
ing the gold-anodized finish
when making suspension ad-
justments.
To avoid damaging the suspen-
sion’s internal mechanisms, do
not attempt to turn beyond themaximum or minimum settings.
For YZF-R1
This model is equipped with adjustable
suspension. The spring preload, re-
bound damping force, and compres-
sion damping force of each leg can be
adjusted.WARNING
EWA10181
Always adjust both fork legs equal-
ly, otherwise poor handling and lossof stability may result.
Spring preload
To increase the spring preload and
thereby harden the suspension, turn the adjusting nut on each fork in direc-
tion (a). To decrease the spring preload
and thereby soften the suspension,
turn the adjusting nut on each fork in di-
rection (b).

Adjusting th e 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 Yamahadealer for any service.

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 situations.
(See the following section for an expla-
nation of the ignition circuit cut-off sys-tem.)
WARNING
EWA10242
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand 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
this system regularly and have a Yamaha dealer repair it if it does not
function properly.
EAU57950
Ignition circuit
cut-off systemThe ignition circuit cut-off system (com-
prising the sidestand switch, clutch
switch and neutral switch) has the fol-
lowing functions.
It prevents starting when the trans-
mission is in gear and the sides-
tand is up, but the clutch lever is
not pulled.
It prevents starting when the trans-
mission is in gear and the clutch le-
ver is pulled, but the sidestand is
still down.
It cuts the running engine when the
transmission is in gear and the sid-
estand is moved down.
Periodically check the operation of the
ignition circuit cut-off system according
to the following procedure.
