Slacken nut1.
Turn the mirror arm to the ap-propriate position.
Tighten the nut to the spe-cified tightening torque, whileholding the mirror arm to en-sure that it does not move outof position.

Spring preload
Adjustment for rear
suspension
It is essential to set spring pre-load of the rear suspension tosuit the load carried by the mo-torcycle. Increase spring preloadwhen the motorcycle is heavilyloaded and reduce spring preloadaccordingly when the motorcycleis lightly loaded.
Adjusting spring preload
for rear wheel
Make sure the ground is leveland firm and place the motor-cycle on its stand.
Your motorcycle's hand-ling will suffer if you do notmatch the spring-preload anddamping-characteristic settings.
Adjust the damping characteristicto suit spring preload.
Adjusting spring preloadwhile the motorcycle is be-ing ridden can lead to accidents.
Do not attempt to adjust springpreload unless the motorcycle isat a standstill.
If you want to increase springpreload, turn knob1in the dir-ection indicated by the HARDarrow.

If you want to reduce springpreload, turn knob1in the dir-ection indicated by the SOFTarrow.
Basic setting of springpreload, rear
Turn the knob counter-clockwise to the limit stop,then turn it back 15 clicks.(Full load of fuel, with rider85 kg)
Damping
Adjustment for rear
suspension
Damping must be adapted to suitspring preload and the surface onwhich the motorcycle is ridden.
An increase in spring preload re-quires firmer damping, a reduc-tion in spring preload requiressofter damping.
The harder the setting, the morethe movement that the spring
strut can make to absorb sur-face irregularities is damped.When you choose a soft settingthe spring strut responds all themore rapidly to surface irregularit-ies.
Adjusting damping for
rear wheel
Make sure the ground is leveland firm and place the motor-cycle on its stand.
Adjust the damping character-istic, using the tool from theon-board toolkit to turn adjust-ing screw1.
If you want a harder dampingcharacteristic, use a screw-driver to turn adjusting screw1in the direction indicated by theH arrow.
If you want a softer dampingcharacteristic, use a screw-driver to turn adjusting screw1in the direction indicated by theS arrow.

zOperation

Risk of damaging compon-ents.
Take care not to trapcomponents such as brake linesor wires.
At the front, secure the strapsto the bottom fork bridge onboth sides.
At the rear, secure the strapsto the rear footrests on bothsides and tighten the straps.
Tighten all the straps uniformly;the motorcycle's suspensionshould be compressed astightly as possible front andrear.

General instructions
BMW Motorrad recommendsthe use of parts and accessoriesfor your motorcycle that are ap-proved by BMW for this purpose.
Genuine BMW parts and ac-cessories and other productswhich BMW has approved canbe obtained from your authorisedBMW Motorrad dealer, togetherwith expert advice on their install-ation and use.
These parts and products havebeen tested by BMW for safety,function and suitability. BMWaccepts product liability for them.
Conversely, BMW is unable toaccept any liability whatsoeverfor parts and accessories which ithas not approved.
Also bear in mind the informa-tion on the effect of wheel sizeon suspension-control systems(77).
BMW Motorrad cannotassess each non-BMWproduct to determine wheth-er it can be used on or in con-nection with BMW motorcycleswithout constituting a safety haz-ard. Country-specific official au-thorisation does not suffice asassurance. Tests conducted bythese instances cannot makeprovision for all operating con-ditions experienced by BMW mo-torcycles and, consequently, theyare not sufficient in some circum-stances.
Use only parts and accessor-ies approved by BMW for yourmotorcycle.
Whenever you are planningmodifications, comply with all thelegal requirements. Make surethat the motorcycle does notinfringe the national road-vehicleconstruction and use regulationsapplicable in your country.
Power sockets
Notes on use of power sockets:
Operating electricalaccessories
Electrically powered accessoriesinevitably place a strain on thebattery. It is essential to ensurethat the battery retains its abilityto start the engine.
Cable routing
The cables from the power sock-ets to the auxiliary devices mustbe routed in such a way thatthey:
Do not impede the rider
Do not restrict the steeringangle or obstruct handling
Cannot be trapped

Effect of wheel size
on suspension-control
systems
Wheel size is very important as aparameter for the ABS. In partic-ular, the diameter and the widthof a motorcycle's wheels are pro-grammed into the control unitand are fundamental to all cal-culations. Any change in theseinfluencing variables, caused forexample by a switch to wheelsother than those installed ex-works, can have serious effectson the performance of the sys-tem.
The sensor rings are essential forcorrect road-speed calculation,
and they too must match themotorcycle's system and con-sequently cannot be changed.
If you decide that you would liketo fit non-standard wheels toyour motorcycle, it is very im-portant to consult a specialistworkshop beforehand, preferablyan authorised BMW Motorraddealer. In some cases, the dataprogrammed into the control unitcan be changed to suit the newwheel sizes.
Removing front wheel
without centre standOE
Make sure the ground is leveland firm and place the mo-torcycle on a suitable auxiliarystand.
with centre standOE
Make sure the ground is leveland firm and place the motor-cycle on its centre stand.
Remove screw1and removethe ABS sensor from its bore.
Raise front of motorcycle untilthe front wheel can turn freely.BMW Motorrad recommendsthe BMW Motorrad front-wheelstand for lifting the motorcycle.
Install the front-wheel stand(83).
