Did you adjust the rebound damping on the wilbers ? A hard, bumpy ride can be caused by too much rebound damping. Also did you go for the standard spring rate or was this tailored for your weight when you ordered them ?
The suspension in essence seems to be working OK, so I'm not convinced the harshness is cause by the suspension at all. Putting new tyres on it helped but not completely. At the next service I'm going to pull the Final Drive and inspect the pivot pins/bearings and see if that might be causing the issue. It is worse on ripples in the road where there's little movement required but quick response in damping. If the pivot bearings are starting to fail I think this would also cause the same problem.
For what it's worth, I'm really really hoping Wilbers will transform my bike........ Mainly because I'm sitting here typing this as the WESA is being fitted![]()
I can't offer any sage advice to the OP about his suspension problem but I can say that Jon at Revs Racing is a top bloke who sorted me out with some custom WESA Wilbers last week.. In all it took about three weeks to order up the parts from Germany and for Revs to fit them. They are a really small outfit based in Halesowen and you are unlikely to find two nicer blokes.
I went the replacement route because the rear damper expired on me a month back. To say that I am unimpressed with this after 14,000 miles and three years is something of an understatment.
All I need to do now is find someone prepared to insure a bike parked on a London street overnight and fitted with non-factory suspension because the BMW scheme ain't interested. And I guess this is a point that anyone planning to fit non-factory suspension needs to be aware of - you ought to tell your insurers that you've done the mod. Whether you do or not is entirely one for your own conscience.

Hopefully it did.
Unfortunately for me 3 months later my rear WESA still isn't working properly
I'm having my WESA fitted on Monday. Any recommendations where to go while they're doing it?


and more to show for it 
Having just done 8000 miles in 4 weeks on my 1st Alaska trip, I can confidently say that the Ohlins I had fitted have transformed the bike ride from good to superb.
It is far more composed on all surfaces from fast tarmac to gravel to dirt. There are some very bumpy roads up through Canada and the bike just sails over them with no banging or clattering.
Worth the money for the riding I do that's for sure

What's not working - the shock or the ESA?
Probably a good job reallyMind you, less expensive than my last weekend in Amsterdamand more to show for it

The shock is no longer adjustable for damping and the only way to adjust the pre-load is manually by connecting directly to the battery.
Make sure all is ok with your stepper motors etc or you could be like me with an expensive non ESA compatible product.
