Engine Management Adaption
General Information
The engine management system fitted to this model is
adaptive. This means that the system is able to learn about
new or changing operating conditions and continuously
adapt itself without needing to constantly make major
adjustments from a fixed baseline setting.
Adaptive changes can become necessary because of
changing rider behaviour, changes in the region in which
the bike is operated (i.e. operation at high altitude where it
was previously used at sea level) or because a new part
may have been fitted which has slightly different
characteristics to the old part. All adaptive changes are
automatic and require no intervention by rider or dealer.
Adaption Status
To see if a motorcycle has fully adapted, a facility named
'ADAPTION STATUS' is provided on the diagnostic tool.
The following adaption details can be examined:
