Thrumming vibration

I'm feeling a vibration at low speed while turning/leaning sharply left. Feels similar to a cupped tire. New Pilot Road II's with about 1,000 miles. Help!
Thanks

My first thought would be Paralever Bearings, get the rear wheel off the floor and check if there is any movement in them, ( Diff carrier most likely)
How many miles has the bike done?

18,000 miles on the clock. Very slight play, if any- while holding rear wheel side to side. Hard to tell from where the movement is coming.

Seems a bit low mileage for Paralever but who knows? Side to side movement is a sign of these bearings having play and the symptoms you describe also point to this, if youve caught them in time adjusting can sometimes sort it.
Not a difficult job but a bit tricky as it involves heating the area around the pivots up to loosen the thread lock BMW use.
Have you got access to a manual?
