Measure the tyre tread depth

in the main tread grooves with

wear marks.

Tyres have wear indicators

integrated into the main

tread grooves. The tyre is worn

out when the tyre tread has worn

down to the level of the marks.

The locations of the marks are

indicated on the edge of the tyre,

e.g. by the letters TI, TWI or by

an arrow.

If the tyre tread is worn to minim-

um:

Replace tyre or tyres, as applic-

able.

Rims

Checking rims

Make sure the ground is level

and firm and place the motor-

cycle on its stand.

Visually inspect the rims for

defects.

Have damaged rims checked

and, if necessary, replaced by a

specialist workshop, preferably

an authorised BMW Motorrad

dealer.

Tyre recommendation

For each size of tyre BMW

Motorrad tests and classifies

as roadworthy certain makes.

BMW Motorrad cannot assess

the suitability or provide any

guarantee of road safety for other

tyres.

BMW Motorrad recommends

using only tyres tested by BMW

Motorrad.

You can obtain detailed informa-

tion from your authorised BMW

Motorrad dealer or on the Inter-

net at www.bmw-motorrad.com.

Effect of wheel size

on suspension-control

systems

Wheel size is very important as

a parameter for the suspension-

control systems ABS and ASC.

In particular, the diameter and the

width of a motorcycle's wheels

are programmed into the control

unit and are fundamental to all

calculations. Any change in these

influencing variables, caused for

example by a switch to wheels

other than those installed ex-

works, can have serious effects

on the performance of the con-

trol systems.

The sensor rings are essential

for correct road-speed calcula-

tion, and they too must match

the motorcycle's control sys-

tems and consequently cannot

be changed.

If you decide that you would like

to fit non-standard wheels to

your motorcycle, it is very import-
