NOTICE
ECA22950
Even when using LCS, the clutch le-
ver must be released gradually toavoid clutch damage.TIPLCS is intended for track use only.
QSS
The quick shift system allows for
full-throttle, clutch lever-less, electroni-
cally-assisted upshifts. When the
switch positioned on the shift lever rod
detects motion in the shift lever, engine
power output is adjusted and drive
torque is momentarily cancelled out to
allow for the gear change to occur.TIP
QSS operates when traveling at
least 20 km/h with an engine
speed of 2000 r/min or higher and
only when accelerating.
QSS does not operate when theclutch lever is pulled. LIF
The lift control system reduces the rate
at which the front wheel will continue to
rise during extreme acceleration, such
as during starts or out-of-corner exits.
When front-wheel lift is detected, en-
gine power is regulated to slow
front-wheel lift while still providing good
acceleration.
ERS (YZF-R1M)
The Electronic Racing Suspension by
Öhlins features electrically-controlled
suspension damping. The system is
controlled by the SCU which makes in-
dependent adjustments of both the
front and rear suspension’s compres-
sion stroke and rebound stroke damp-
ing forces. There are two modes,
automatic and manual. Automatic
mode is an active suspension control
system which actively adjusts suspen-
sion damping forces based on running
conditions. Manual mode is a finely-tu-
neable traditional suspension set-up.

4. If the drive chain slack is incorrect,
adjust it as follows.
EAU34318
To adjust the drive chain slack
Consult a Yamaha dealer before ad-
justing the drive chain slack.1. Loosen the axle nut and the lock- nut on each side of the swingarm.
2. To tighten the drive chain, turn the drive chain slack adjusting bolt on
each side of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting bolt on each side
of the swingarm in direction (b),
and then push the rear wheel for-
ward. NOTICE: Improper drive
chain slack will overload the en- gine as well as other vital parts
of the motorcycle and can lead
to chain slippage or breakage.
To prevent this from occurring,
keep the drive chain slack with-
in the specified limits.
[ECA10572]
TIPUsing the alignment marks on each
side of the swingarm, make sure that
both drive chain pullers are in the sameposition for proper wheel alignment.
3. Tighten the axle nut, then the lock- nuts to their specified torques.
4. Make sure that the drive chain pull- ers are in the same position, the
drive chain slack is correct, and
the drive chain moves smoothly.
