I'd say "none." Categorically.
If there's any noticable play, even less than 1mm, it's soon going to be more than 1mm. My 1150 had a knackered bearing and I doubt there was 1mm play, but a noticeable click when rocking it. Dealers replace dit under warranty. Don't see why 1200 should be any different.

none!!!!!!!!
BMW say 1mm is the design limit - got a BMW document somewhere saying that it is a consequence of the type of bearing used and not a result of wear - this suggests that even brand new bikes can have this much play. I will try to find the document and post it up here.
P.S. The explanation near the end of the link posted by ebbo.

R 1200 GS
1: In the rear drive of the R 1200 GS the ring gear is supported by two types of bearings: one floating bearing and one fixed bearing without preload. Inherent in this design is a small amount of bearing play at the rear wheel. With all components manufactured and assembled to stated tolerances it is possible that play in these bearings can be felt and measured at the rear wheel. This type of bearing play has no effect on motorcycle handling or on the durability of the bearings.
2: There is a possibility of play developing between the splined wheel flange (P/N 33 17 7 668 659) and the axle tube of some motorcycles manufactured prior to 08/2004, US VIN# ZL 76187.
1: In the event of a customer complaint, an inspection and measurement of rear wheel bearing play is to be performed as described below. With cold components the total play (back and forth travel) allowable at the wheel rim edge is 1mm(maximum). Refer to the R 1200 GS Repair Manual CD for measuring procedures as well as temperature definition of "cold components". Replace the entire rear-wheel drive assembly if the play exceeds specifications.
2: If the complaint is "bearing play at the rear wheel" you must first check that the
splined flange is secure before performing the measurement noted in point #1. When rocking the rear wheel back and forth, you must first make sure there is no movement between the wheel flange, the rear wheel and the axle tube.
If play is noticeable between these components you must replace the entire rear wheel drive assembly (complete with flange). Replacing the splined wheel flange only will not solve the situation, because in all probability the splines on the axle tube will have suffered some degree of wear as well. If you are in doubt, you are requested to contact your respective Aftersales Business Consultant.
Warranty: Covered under the terms of the New Motorcycle Limited Warranty.
Important Note: Screw 1 is a drain plug for repair-related oil changes; it is
not for checking the oil level. When filling the rear drive assembly with oil,
pour in the defined quantity (0.25 l for initial fill, or 0.23 l for oil changes)
through the bore for the ABS sensor. We highly recommend using BMW

I noticed the same problem in my 1200 GS 2007 last week. I sent it to service and the diagnostic was a flange failure, which seems to be another problem afecting tons of GS around the world.
Just to mention I had already experienced the EWS! failure. Too many problems in six months for a motorcycle that costs US$ 45.000,00 in Brazil.

PLAY
about 1mm is the norm even on new bikes. due to the huge needle roller bearing in the axle. give it a wiggle and a small amount is fine, if it feels excessive take it to a dealer for 2nd opinion.
make sure centre stand isnt loose as this will give the same feeling. check its tight.

When hot, ie after a long fast run mine has a small amount of play - certainly less than 1mm but I've never bothered to measure it. When cold there is no play at all. It's been the same for the last 14,000 (since it was new) and hasn't got any worse.
Changed the final drive oil at 12,000 and it was reasonably clean, ditto the magnetic plug.

My understanding was that flange failures only happened on the early 2004 bikes and was fixed by an update later the same year. I questioned BMW UK about this before I ordered my 2005 bike and they assured me (via email) that an update had taken place in September 2004 to address this issue.

hi mate, my gs1200 07 went in for a annual inspection last week, told them about a small amount of play at the rear wheel, they say rear wheel bearing needs replacing, only done 9k, will be done under warranty thankfully
