Would really love BMW to do a software upgrade to be able to move the suspension up in notches of 1cm at a time, bit like the manual settings suspension, although it works well, between MINI, MAX, AUTO there has to be some other comfort zones.

I can see why some people might want that facility, but can also see why BMW don't provide it. The current system, in AUTO mode, appears to be designed to maintain an optimum (in BMW's view) ride height and therefore geometry, regardless (within reason) of load, and I have to say I think this works exceedingly well.

As part of this I believe it also tweaks damping to suit the load on the bike, which it can accurately measure by how much preload it has had to apply to get the bike back to the optimum ride height. This means that these load related damping adjustments, which I think are very important for good handling, can be more accurate than the old manually selected rider, rider + pillion, rider + pillion + luggage presets. These, though better than no adjustment, would only be accurate for loads which conform exactly to the average weights those presets are designed for.

I realise that users can also influence the damping through the mode selections, but I assume these just bias the settings either side of the load related base level which the bike sets automatically, and overlying this is the dynamic adjustment which is supposed to fine tune the damping based on road conditions and riding style.

If users were allowed to randomly select a ride height, regardless of load, then it would be very difficult for the system to choose the correct amount of load related damping. The MIN and MAX settings are presumably special cases which are not intended for general use, so I guess they make some default initial damping settings for when these modes are in use.

Overall quite a complex system, so no wonder they don't want users fiddling with ride height settings.

I guess if you want the freedom to do this you need to go with a non-ESA suspension bike but of course you then lose the undoubted benefits of automatic adjustment. I find this is pretty much indispensible when frequently changing between two-up and solo riding, so I'm willing to lose a degree of manual control in exchange. However, I recognise that this is not the case for everyone, and particularly those who always ride with the same load and would like to manually tune the suspension.

Fred I do not doubt for one moment that the software and computers in these bikes are certainly smarter than we are, its just nice to have the choice if needed, example if I set the bike to MIN in Dynamic mode, given my weight 100 kilos, it feels like it is bottoming out, if I could just bump it up a cm or 2 it might be another ride, do not get me wrong I am not knocking it, just like to fiddle around now and again.

I concur, it would be an advantage if it were possible. I mean, the adjustment could be user defined and infinitely adjustable throughout the suspension travel and damping range. BMW could also do it both ways to select the suspension as is or manual. I would imagine it would be just programming task.

I understand your desire to fiddle - I've spent many hours playing with suspension settings on previous bikes, though not always very productively! I just don't think these bikes lend themselves to that. For example, if you are putting the preload on MIN and you weigh 100 kilos it is not surprising if it is bottoming out. If you then want to be able to raise it 2cm from that point to stop that, you are really trying to do manually what AUTO mode will do for you automatically. Is there a problem with AUTO mode that means you don't want to use it? If it is just a question of distance to the ground, then rather than mess with the preload I think BMW would rather your use seat type/adjustment, and there is also the lowered suspension option if needed, though that would probably be a bit expensive to retro-fit!

No problem with reach to ground Fred 6ft 2 inches, its just a desire to fiddle, maybe I should just be happy with what I have, and forget my Harley days.

I agree that it should be technically possible, but I think the issue is that this would allow you to set what BMW would regard as a non-optimum rear ride height, which would affect steering geometry, and would also allow you to set damping not well matched to the load, both of which could adversely affect handling, and even in extreme cases be unsafe. Not sure the mothership is going to allow that on an electrically adjustable suspension where they are able to prevent it, in case they could be held liable for any unfortunate consequences. They can't stop you on manually adjustable suspension, though possibly the range of tweaking available to users on non-ESA bikes could well be less, and so maybe less likely to cause serious problems.

I see - just trying to convert it to a Low Rider then. Maybe a GS is not an ideal starting point LOL! :)
