Im not sold on the difference!! Sorry it may be just me.
As for setting each map. The manual says (im trying to remeber im at work).
Shift the bike to the desired map/gear N,5 or 6. This should be done with the bike not running. Then turn on the ignition key and turn the key off within 5 seconds(ithink).
To varify the setting, turn on the ignition and the gear display will show the desired setting (Blank is neutral) as a confirmation.
So bike off, shift to desired gear/map, key on, key off, switch to neutral then turn on ignition and watch for confirmation on gear display Blank,5 or 6, then the bike should switch to 'N'
Hope this helps
