MY bike is NON ARH, please bear in mind as you read the following.
Update: I have asked my dealer to formally approach the moco for details of the rear suspension behaviour under normal working conditions. my preload on the rear shock is fixed, there is no change whether i'm solo or whether i'm packing rider and pillion. when solo i'm on tip toes, with pillion I can flat foot and drivers flash me because my headlight is in the air. The whole idea here is to always ensure the correct amount of rider sag, the bike should more or less remain level regardless of load, all controlled by varying the preload on the spring to compensate for increasing rider loadings.
In the load settings menu, there is Auto which i'm guessing takes care of rider sag automatically depending upon the load. then as an alternative you can manually select Rider, Rider and luggage, Rider and Pillion, Rider and Pillion with luggage. as far as im concerned, each scenario should add a bit more preload. Mindful of the fact this bike has no pump to change the preload settings, it should happen as you ride off, gradually pumping up to the correct ride height. {My multistrada has a pump, you can see the bike rear end moving up and down at a standstill as you select different loads.
When i first got my bike, standing at its side and at each switching on of the ignition, the bike would sense it was carrying too much preload (Based upon the previous ride} and release pressure from the shock, lowering the bike. As I rode away it would jack up the preload to compensate for the rider weight. Now nothing ever seems to change, it seems fixed at one preload whatever settings I select from the load menu.
