ESA shock worn out??

2007 k1200GT with ESA. I used to notice a dramatic difference between the comfort and sport settings. Now I cannot tell a seat of the pants difference when I ride down a rough road. I am able to measure with a tape measure that at least the preload changes when I use the different preload settings. I had it to the dealer and they tell me that there is nothing the matter with it, but my butt tells me it is not the same. The bike has 26000 km on it. Would it be worn out already to account for the difference? Should this be a warranty item? Thanks for any help

Shocks are usually considered wear items, like clutches or brakes. That said, some dealers have replaced ESA shocks under warranty because they have not functioned as designed. That usually has to do with the preload not changing instead of the damping, but there is a precedent there.

My '07 GT still has the factory shocks on it at 114K miles. Yes, they are worn out as the bike wallows when pushed hard, but I can say that the ESA still functions as designed. That is, there is still a noticeable difference between the different preload settings (although all of those settings are much weaker), and also changing the damping settings when riding does make a difference. They are nowhere near what new shocks are, but the basic functionality is still there.

But any warranty claim has to be processed through your dealer, and to do that first they have to believe that there is a repeatable problem . . .

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Hi all - new to this forum. I joined specifcally because I have the same issue as posted above, i.e. my 3 yr old K1200S with 30K on the clock has ESA with no tangible difference between comfort/normal/sport. Preload works fine.

My local BMW dealer has looked at it and can't find anything wrong, i.e. no broken cables, the computer says it's all working fine - but with several of us bouncing up and down on the bike whilst switching between comfort/sport it's nigh on impossible to tell any difference.

We compared that to a bike they had for sale with 17K miles on the clock and the difference between ESA settings was very noticeable.

I'd really like to know what the problem is before seeking either replacement shocks or getting the originals rebuilt by WP.

When it comes to ESA suspension, getting it sorted by a process of elimination is an expensive hobby!

Cheers,
mark
