ESA Preload Adjustments - How Much Change?

How much does your K1200GT raise or lower when you press and hold, then release the ESA button to adjust the preload?

It probably depends on the weight. I switched from solo (min preload) to 2-up (max preload) this morning, with fully loaded bags. I was standing at the bike at the time, so it's hard to say, but I'd guess the seat came up somewhere betwen 2 and 3 centimeters - not very much.

Didn't move at all after upgrade to computer software 11. Working now and only moves about 1 cm from single head to two heads. When bike was new it moved about 2 - 3 cm but I guess the shock is getting more worn now at 17K miles. Anyone replaced ESA rear shock yet? I have to say I would not get ESA again, my rear shock seems more worn than my front and on a conventional setup you could just dial in more preload and take some preload off the front etc. Bike feels firm at front but lose at back, anyway getting used to it.

My shocks are at 17K, and seem to be holding up well. (We need a knock-on-wood smilie.) Rear goes up and down 3+ cm. between 1 and 2 helmets. I wouldn't be surprised if the preload pump and slave needed maintenance after 20K, however.

Havn't measured mine either, but I do feel it going up or down while sitting on it and making the adjustment. At 17k miles I could feel the rear softening up a little from how it felt new and now at 25k miles it's even mooshier on bumps. I'm tempted to start using one setting higher than I'm supposed to do the same thing as cranking up the preload on a non esa bike and see if it helps. Although that won't help if I'm 2 up since theres nothing higher than that. I really like the convienence of ESA but not if I'm putting enough miles yearly to wear them out since I don't have a spare 3k a year to replace those shocks in addition to the rest of the "wear" items.

Go to the sport setting on damping to get rid of the mooshes. Preload shouldn't change mooshes, although the bike starts at a higher position when the moosh starts.

Once sport setting gets mooshy, it's time to rebuild.

And therein lies the $3500 problem. The damn things aren't even rebuildable!

They can be rebuilt, and the manufacturer recently reported that BMW reversed their no rebuild policy, or maybe the manufacturer just said to hell with BMW. The original no rebuild was a policy decision, not a technical limitation.
