Rear Softer Spring on suspension

[mickthesaw]

Has anyone given any thought to a softer spring for the esa rear unit.?
Could it be done to cure the hard suspension in road mode.?
Most of my riding is B roads and unclassified, loving the bike but would like a softer mode.?
A roads its ace but on UK crap roads my back is getting a pounding... lol
900 miles on now and its bloomin marvelous

It is a pretty firm ride.  This would be a good question to direct to BMW.  There are a lot of suspension/shock people out there that may be able to direct you to an independent dealer that could make some mods as well.  Good luck......

Being a complete numpty with regard to suspension I don't know whether it's the spring that makes it so firm but, like you, most of the roads I ride are minor roads which have suffered from neglect over the last few years and it's sometimes hard going. If a spring change helps I'd be interested.....

Well not good news,I've contacted Hyperpro in Holland this morning and they have already tried to change the springs from a BMW dealers bike their.
Apparently it cannot be done as the electronics rely on the spring setting and changing the spring completely messes the suspension up.
I guess we will just have to keep pestering our Dealers about this issue and hopefully a software change might solve it.
Knowing BM it wont happen quick if at all

Give Wilbers a try, they had  a spring available for the S1000r if i recall, but what you're experiencing is exactly why i went with the sport version.

Means i can switch springs out front and back

Thanks,but from what Hyperpro said I think its a no no unless you change out the whole unit.!
I've fired an email to BMW Berlin about this and the heated grips to see if they can do a software update in the future.
Might be futile but unless they here from their customers nothing changes and contacting BMW UK is a waste of time.

would you believe I've just found this on their homepage, looks like it was only launched on the 24th.

Couldn't tell you what it says mind :)

Go onto one of the Ducati forums,Ducati.MS will do and look around 2014 at what went on with the Ohlins version.

[mickthesaw]

Hi Winger, thanks for that it looks like they put a heavier spring into their Ohlins suspenion,
But do we know who manufactures the XR D-ESA setup.?
Reading up on the D-Esa its completely different from anything that has been done before on ESA bikes going back to the GT's
Its supposed to monitor your riding lean angles road surface etc and adapt to the conditions.
Hyperpro were adamant that a springe change wouldn't work,perhaps speaking to Ohlins or Sachs might give a different answer..?
I dont want to/ or fancy spending another £1000 on a rear shock change though.
