We need BMW/Rotax to face and fix this problem for us.
As I said my knowledge concerning motorcycle electrics is very limited, but yes it seems very logical. BMW could sure fix that but I am not convinced that they will do anything.
Although I am not convinced maybe a heatshield as JRWooden suggested is worth a try, it does not cost a lot and if it only keeps a few degrees of heat off the darn rotor it may extend lifetime.
