At high road speeds, tyre

valves installed perpen-

dicular to the wheel rim have a

tendency to open as a result of

centrifugal force.

In order to avoid sudden defla-

tion, fit valves installed perpen-

dicular to the rim with valve caps

complete with rubber seals and

make sure the valve caps are

screwed firmly on to the valves.

Make sure the ground is level

and firm and place the motor-

cycle on its stand.

Check tyre pressures against

the data below.

Tyre pressure, front

2.2 bar (one-up, at tyre tem-

perature 20 °C)

2.4 bar (two-up and/or with

luggage, at tyre temperature

20 °C)

Tyre pressure, rear

2.4 bar (one-up, at tyre tem-

perature 20 °C)

2.8 bar (two-up and/or with

luggage, at tyre temperature

20 °C)

If tyre pressure is too low:

Correct tyre pressure.

Headlight

Adjusting headlight for

driving on left/driving on

right

If the motorcycle is ridden in a

country where the opposite rule

of the road applies, its asymmet-

ric low-beam headlight will tend

to dazzle oncoming traffic.

Have the headlight set accord-

ingly by a specialist workshop,

preferably an authorised BMW

Motorrad dealer.

Headlight beam throw and

spring preload

Headlight beam throw is gener-

ally kept constant when spring

preload is adjusted to suit load.

Spring preload adjustment might

not suffice only if the motorcycle

is very heavily loaded. Under

these circumstances, headlight

beam throw has to be adjusted

to suit the weight carried by the

motorcycle.

Consult a specialist work-

shop, preferably an au-

thorised BMW Motorrad dealer,

if you are unsure whether the

headlight beam-throw setting is

correct.
