Chances are your warranty will run out before the stator fails. Joel Wisman reports seeing dead stators in the shop he worked at as early as 20K to as high as 50K but he's never seen any F800xx bike go more than 50K miles on the original stator. Obviously BMW figured out that the lack of oil cooling is prematurely killing stators, hence the redesign of the rotor with more openings to permit oil to cool the stator. Since there is no recall, owners are left to foot the bill when the stator fails beyond the warranty.
