TIP
Although the total number of clicks
of a damping force adjusting
mechanism may not exactly match
the above specifications due to
small differences in production, the
actual number of clicks always
represents the entire adjusting
range. To obtain a precise adjust-
ment, check the number of clicks
and modify the minimum and stan-
dard specifications as necessary.
When turning the damping force
adjusting bolt in direction (a), the 0
click position and the 1 click posi-tion may be the same.
For YZF-R1M
This model is is equipped with ÖHLINS
electronic racing suspension.
The compression and rebound damp-
ing forces are electronically adjusted.
(See ERS on page 4-19.)
Spring preload
The spring preload adjustment is per-
formed manually. 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.
[ECA22770]
4. To increase the spring preload and thereby harden the suspension,
turn the adjusting bolt on each fork
leg in direction (a). To decrease
the spring preload and thereby
soften the suspension, turn the ad-
justing bolt on each fork leg in di-
rection (b). 5. Attach the coupler on each fork.

nal position.1. Rubber cover

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.
NOTICE
ECA10102
To avoid damaging the mechanism,
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, fast compres-
sion damping force, and slow
compression damping force can be ad-
justed.
Spring preload
1. Loosen the locknut.
2. To increase the spring preload and thereby harden the suspension,
turn the adjusting ring in direction
(a). To decrease the spring pre-
load and thereby soften the sus-
pension, turn the adjusting ring in
direction (b).
The spring preload setting is deter-
mined by measuring distance A.
The longer distance A is, the high-
er the spring preload; the shorter
distance A is, the lower the spring preload.
Use the special wrench includ-
ed in the owner’s 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 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.

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.

Ignition circuit cut-off systemThis system prevents in-gear engine
starts unless the clutch lever is pulled
and the sidestand is up. Also, it will stop
the running engine should the sides-
tand be lowered while the transmission
is in gear.
Periodically check this system via the
following procedure.TIP
This check is most reliable if per-
formed with a warmed-up engine.
See pages 4-2 and 4-3 for switchoperation information.
