GENERAL INFORMATION
TECHNICAL FEATURES

ABS WITH MODE-SELECTION MECHANISM (REAR ABS OFF MODE) (CRF1000A/D)
SYSTEM OVERVIEW
The CRF1000A/D (ABS type) is equipped with an ABS with selectable modes. In the ABS with mode-selection mechanism, the
front ABS functions as a regular ABS, but the rear ABS can be cancelled; this mechanism gives greater freedom of off-road riding
while ensuring the safety.
To switch between the modes, press and hold the rear ABS switch for more than two seconds when the motorcycle is stopped, then
the rear ABS OFF indicator blinks. Releasing the rear ABS switch while the indicator blinks turns the indicator to stay on and
cancels the rear ABS.
When in the rear ABS OFF mode, only when the rear ABS OFF indicator fails, the fail safe function is activated to actuate both front
and rear ABSs.
Neither the front nor rear ABS is actuated by other types of failure; for those failures, the ABS indicator starts blinking to warn of the
failure.
To cancel the rear ABS OFF mode, press the rear ABS switch for more than two seconds.
