The bars on the RS can be changed if you want to. It looks like the triple tree on the RS is the same as the R. The brake and clutch hoses are the same. I checked when I was looking at bar backs for my R bike. I do not know what BMW wants for the tubular bars, but they are not cheep.The bars on the right are higher than the standard RS bars.
The bars on the left are lower than the standard R bars.
To me they look the same but it's hard to tell because of the different angles.
