This thread made me think, maybe since I have a R60 and a R100RS, I should take off the right cover off both and swap them.....a peanut cover on the right side of the R100RS, standard on left, oppisite of same on R60!

An easy way to tell if they are factory or not, the repros do not have the small roundel cast into the inside like the factory ones do.
As far as the interchangeability is concerned, think of it this way, they all share the same gasket. That is a give away right there. I've even put a pair of the 70-76 covers on a /2 (used a longer center stud) and it looked like a R50S!
Actually that is where they took the design from. The R50S had one of a kind valve covers. They were a little shallower with one less cooling fin, but looked liked the later /5 /6 covers.
Late 1976 (77 model year) introduced the squarish valve covers in plain and then Black. They are actually different from left to right which is why they are marked links und rechts accordingly.
The angle of the fins are off kilter to match the offset of the fins on the heads. They will work on either side but look a little odd when put on wrong.
Yes they are thicker and stronger and also quieter.

I've had good luck with the repros (peanut)I've gotten from Siebenrock. They are actually very nicely made. I'll have to ask Siebenrock if they are made in China. Considering they are very nearly 1/2 the price of the BMW ones I think they are a outstanding value, ($60 versus $112 @ price). I also hate to contradict Robert , but you so seldom get a chance. Where are they less robust? I haven't found that to be true and I weighed Original BMW covers and the Siebenrock repro and the repros were just short of 3 oz. heavier. Definitely more metal in them.

Not only peanuts, but using an "old style" air cleaner cover with the round air cleaner inside. I DO like the retro look....

Bingo. I believe that the 1995 GS Classic also came with the peanut covers. And possibly the early 90s R100R?

Yes, they are interchangeable.

As for durability, I can't say anything about the Chinese covers but I've seen both the peanut and /7 covers wear through in a slide on pavement. If gthe Chinese covers are less durable then it's just a matter of sliding distance before they wear through relative to the others. Either way, you've got to turn them upside down.

JT, I love ya man, but let me explain a few things to the listenning audience.
Way back in my days with Bobs BMW, I was the guy that did all the importing from Siebenrock, Jeckel, Ulis, to name JUST the German compamies.
Once upon a shipment of the valve covers, They all arrived in boxes with Chinese writing under the flaps.
I asked the Siebenrock contact about this and If I remember correctly, was given the the typical haughty German silent treatment then complete denial. As if i had insulted him! ( I'm German and Dutch, I can say this shit) ( Plus I'm retired now and don't give a rats ass anymore) OY such a book i could write!
ANYWAY,
Back in those days, 1998ish, we were the only game in town for alot of this shit, and Bob Henig led the way for most of the current importers.
As far as the cheap valve covers were concerned, in those days they were lighter and they were supplied with "6" mm studs that were no way near 6mm.
we had to exchange all the supplied studs with BMW factory studs when I discovered this after a customer complained when he stripped out the threads in the covers. Typical Chinese fasteners, undersized.
Just sayin' things morph and change because of companies like Bobs BMW and his staffers (like me) who beat these guys up to offer a better product.
Why do you think I started WireWerkes?
Because the harnesses we were importing through Ulis and Theofried Jaeckel etc were absolute CRAP.
I found this out after attempting to install one on my 64 R60/2

tata for now

I have a set of repros on my GS and they broke falling off the sidestand.

There is more to strength than just thickeness, but they are thin where it counts.

Alloy type and temper counts for a lot too. The repros dont polish up like OEM and discolour easily, so they are likley a different alloy.

Mine are the type with through bolts in place of studs, cant remember where I bought them, might have been Boxxerparts.

Like you, I like the older style covers also and put them on my '78 R100/7. As you now know, the fit fine and IMHO do look better than the square ones. I have seen them recently on craigslist also.
