Checking tyre tread depth
WARNING
Riding with badly worn tyres
Risk of accident due to im-
paired handling
If applicable, have the tyres
changed in good time be-
fore they wear to the min-
imum tread depth permitted
by law.
Place the motorcycle on its
stand on firm, even ground.
Measure the tyre tread depth
in the main tread grooves
with wear marks.
Wear indicators are built
into the main profile
grooves on each tyre. 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 min-
imum:
Replace tyre or tyres, as ap-
plicable.
WHEEL RIMS
Check wheel rims
Place the motorcycle on its
stand on firm, even ground.
Visually inspect the rims for
defects.
Have damaged rims inspec-
ted by a specialist workshop
and replaced if necessary,
preferably by an authorised
BMW Motorrad Retailer.
WHEELS
Effect of wheel size on
chassis and suspension
control systems
The wheel sizes play an essen-
tial role with DTC. In particular,
the diameter and the width of
the vehicle's wheels are pro-
grammed into the control unit
and are fundamental to all cal-
culations. 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.
