d Warning:
If there is a fault in the ABS
system, the reserves of safety
normally afforded by ABS are
not available until the defect
has been put right.
There is a risk of dropping the
motorcycle if the brakes are
applied too hard and the
w h ee ls l o ck o r th e r e ar w h ee l

result of a high level of tyre
adhesion. Have the defect
rectified immediately by a
specialist workshop, prefera-
bly an authorised
BMW motorcycle dealer.
