Cush drive rubbers.F700gs

[wreck diver]

Is there a usual mileage the Cush drive rubbers need to be replaced?
Are they much to replace?
Thanks

In my previous 800GS, i replaced about every 25k miles, as most were cracked/broken by then. From memory there are 4, a little bit under £20 each? Replacement is straightforward with some silicon lube to help.
