The manual only says "Z" chain. I would check with dealer. It might be longer than the "R" chain as suspension is different.does anyone know the size/number of links of the stock chain? i suppose that it might be the same like the r...
thank you in advance
I thought I read the GS was a "Z" ring and the R was an "O" ring?:surprise:There seems to be some controversy over exactly how many links are in the chain but I want to say that the R and the GS do indeed use the same final drive chain, part # 33 83 8 566 489 which retails from BMW for about $117 US .
Here is a very good parts information resource for BMW motorcycles. It takes a little bit of practice to navigate and I suspect it works better with a PC than a smart phone or tablet but it works very well if you need to get a part number.
