BMW R1200R R1150R/T F800 K1200R R1100R/T R1250R RnineT Message Board

Is there a different head design between the R1150RT and R1200RT? Specifically, does the 1200 head still use a single rocker arm for both intake and exhause valves, vice a normal design of two rocker arms? This seems to make the valve adjustment rather tedious (say either expensive if done correctly...

First, I'm a lurker, thinking about a Boxer someday. Have a cruiser (NO, not a HD).
Am I understanding correctly, that ONE rocker arm activates both intake and exhaust valves?
I have not seen such an arrangement before.
