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.

Use extra care to avoid scratch-
ing the anodized finish when
making suspension adjust-
ments.
 To avoid damaging the suspen-
sion’s internal mechanisms, do
not attempt to turn beyond the
maximum or minimum settings.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 equally,
otherwise poor handling and loss of
stability may result.Spring preload
Turn the adjusting nut in direction (a) to
increase the spring preload. Turn the adjusting nut in direction (b) to
decrease the spring preload.
To set the spring preload, turn the ad-
juster in direction (b) until it stops, and
then count the turns in direction (a).

electronic racing suspension with gas
reservoir. The compression and re-
bound damping forces are electroni-
cally adjusted (see ERS on page 4-20).
The spring preload is manually adjust-
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
fork. NOTICE: To prevent dam-
aging the couplers, do not use
sharp tools or excessive force.

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

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.
