I know the 'Select' button by the clutch handle, toggles you through the different displays down on the tank. And I discovered that there's only one button on the front of the tank, not 3. Two are just screw fasteners. I assume the one button, resets the trip mileage counter. Hope you're enjoying your ride!i too would like to know this. ive not been able to locate anything related to this. also i have only just now noticed on the left hand side right behind the clutch theres a little button labeled "select" and i have no idea what thats for. altho, if i were totally honest, i haven looked too deep for this. i only just found it.
