Enduro ASC 2012 R12GS

From what I can tell this option is available with low suspension

Is it available as an add on or factory installed only?

Cheaper from factory but can be done either way.

Thanks

Already have the bike and it does't have ASC . I'll have to add it

I had it added to my 09 GSA. Software update and new left switch gear to add the button. I still don't think I needed that last part though.
