I have the S without ARH. When new, upon turning on the ignition the bike would always drop to minimum preload and then gradually pump up to normal ride height. At 450 miles on a 150 mile trip I noticed the ride height was very low and when I stopped I could flat foot either side. eventually the bike started to pump back during riding to a normal height.

Today, I’ve noticed that the bike no longer drops to minimum preload at ignition on, it stays with about 50mm of preload movement on the rear spring. I’m flummoxed, for a supposed automatic system, mine just seems random.

Thanks very much Patkin you've now got me worried 😉 That is meant to be a light hearted comment but I am worried.
I,ve just been out to my garage ,the bike is on the centre stand and no movement whatsoever. Is that because its on the centre stand. When I have been riding the flashing suspension light does come on so I have only assumed it is working correctly. Mines the PAS by the way.

Your bike has ARH? In any case, the suspension preload is not changed with the bike idle, there is no pump. As you ride the bike, the shock movement pumps up pressure. If too much preload, a valve opens to reduce it.

Update on this post, my bike still doesn’t change the preload in any noticeable way. Been through first service, nobody knows how this setup is supposed to behave. Most info I’ve got so far was from Showa who seem to be developing a similar system for the aftermarket.

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.

I have ARH and the option to adjust preload as per to payload isn't avaliable. I take it adjusts automatically. I've not carried a pillion yet and don't have the lugagge yet either, so nothing to compare with directly. It's also worth noting as an aside that the max payload of a Pan America Special is around 215kg with alloy wheels and around 201kg for the spoked wheels.

Can only suggest you take your bike to the dealer and ask them to check it out?

My bike was in the dealers for over 3 months. First they suspected the BCM then they ordered a new rear shock which as far as I know still didn’t arrive. I demanded and received a new bike in March this year, this was provided by my dealer, HD UK customer service are useless. The new bike has ARH, it still does not provide enough preload with a 60kg passenger. In my opinion the Pan America suspension is a shambles, I may consider the base model next time, meanwhile I have a placed a deposit on a Lowrider ST.

Someone on another forum found an issue with the rear shock wire connector. The connector consists of 2 rows of black and white wires with pin numbers alternating white then black according to the PA wiring diagram, but the actual connector does not match the diagram.
He doesn't state that he is an HD tech but that is the implication and that correcting the wiring pins fixes the ARH issues.

Onwards and upwards! Enjoy the new one when it comes.

I have had the exact same fault on my non ARH 1250S, the dealer blamed the software and reverted it back to old. This caused more faults, my 1250 would lift it self to the point i was unable to touch the ground, and even with a pillion there was no give in suspension.
The dealers have replaced my bike for a one with ARH which works great (for now)
I am about to embark on a trip to European Bike week in Austria from Teesside and have doubts about the bike being able to cope.

Fingers crossed all ok.🤞

Just an update just incase someone is searching on this issue.
Bought my 2022 Special on June 17 2022. Was told all recalls and updates were checked and done.HAHAHA

I looked at that connector deal that Knobbin showed. My suspension was acting weird at times. No codes. Sure enough connector was wired wrong. Its been stated that the Stealerships is supposed to check that when updating and at the 1000 mile check up. Want to bet. Harley techs are saying that 80% of the PA's are wired wrong.
I fixed it myself being a Car dealer tech. for years. Now the ARH acts like its supposed to and its pretty cool. I use the custom setting B ride mode and have it with a slight delay. When i come to a stop a few seconds later it lowers. Im 6' 1" so the lowering i really dont need but at 20k if i paid for it i want it to work.
BTW wife is 5'1"

Well, the day before my trip I had the bike serviced (A big mistake in hindsight) , new software update and a nightmare of issues again, bike surging with a tick over of 2000rpm, to be fair to the dealer, they couldn't have been more helpful, sending the tech to my house to assist with a reset.
On the trip itself the bike was plagued with a lot of codes and just pumped the suspension to max with no movement. this happened twice through the black forest.
The dealers contacted the tech specialist in Austria who subsequently changed some things on the bike, all seemed fine until I put the bike into transport mode for the return ferry.
On restart after the ferry trip the bike absolutely just gave up on everything apart from running.
Multiple resets and restarts and eventually had some sort of info on the dash, enough to ride home.
The ride home was terrible, suspension pumped to the max with no movement.
I really like these bikes as they are different to all other adventure tourers, but I just wish they could get their act together and solve these issues.
Bike going back in tomorrow, will see how she fairs.

My new 2 week old bike is just a surprise box. Today the suspension would not go down and there is a yellow triangle on the top left side of the screen. Rode the bike for one hour, stop for gaz . Restart the bike and suspension going down !! Last week, the shifter became inoperable, can’t shift up or down it is like the shifter on not active . The bike got stuck in second gear for a few minutes and then was normal . I kept riding and then stuck in 6 th gear , it won’t downshift . ??My dealer has no idea what is going on and say the never seen this problem ..
