New Clutch Friction Plate Thickness?

Does anyone know what the new OEM BMW Clutch Friction Plate thickness is? Specifically for an 1150RT.

Thanks
Rod

Factory manual lists most everything but the thickness when new. I don't think there is much more than 5.5mm there on a new one. If you have a friendly dealer maybe they will measure one from stock for you?

Technical Data 21 Clutch R 1150 RT

Type Single dry plate with high-leverage pressure plate
Clutch plate dia. mm (in) 165 (6.4960)
Wear limit mm (in) 4.8 (0.1890)
(Measured with caliper tips pressed by hand against rivets of clutch plate)
Operation hydraulic
Piston dia.
Master cylinder mm (in) 13 (0.5118)
Slave cylinder mm (in) 24 (0.9449)
Hydraulic fluid, clutch-release circuit DOT 4 brake fluid

6.8 mm

I have measured 6.4mm on a new 1150 disc.

Thanks folks, I guess I'm in good shape with 6.2.

I know I have plenty of wear left and both the xmission and clutch splines are perfect. I'm just trying to Guesstimate my rate of wear.
It's a 2003 R1150RT with 85K. Unfortunately I have very little maintenance history on it.

Suspect it might not be original with that mileage and little wear.
Just sayin'

Yes, That's my theory also, I'm guessing it got new transmission splines and clutch not too many miles back. Everything just looks way to good! It did have a notchie drive shaft front u-joint too. I got a good, low mileage used one from Beemer Boneyard to replace it. I had to get a leaking pinion seal on the final drive fixed too.

FYI, my spare Trans was original replaced by PO at 80k, splines perfect disk at 5.8mm.
Current Trans with 96k (2 yrs ago) splines perfect, not sure about the disk, it's still going. It now has at least 114k on it.
I'm rebuilding the spare and will install with new disk. Coming soon!

Well, that is certainly interesting. So now I'm not sure about mine, maybe it is original? The one thing I do know now is it's current condition. So I guess I will just put it back together and go riding knowing that my drive train is in very good shape. I will monitor and check it again in a few years.

Thanks
