Who knows what this lower digital window is for?
Gear indicator, for sure... and what more?
I wondered the same so asked someone in Motorrad's communications department. Here's what he said the LCDs would show:
The displays show following functions:
date and time
daily trip (1 and 2)
average consumption / actual consumption
riding mileage after fuel warning light has turned on
heated grips "on"
Assume the gear indicator would appear in the tachometer LCD, as a large number, at far right, but have not seen photos of both displays turned on.
