Mixing brands is not a problem, its mixing radials with bias ply tires that could land you in hot water.
There is no need to adjust the ABS, either, as the 0.47 inch taller Bridgestone actually corrects the approximately 7% speedo deviation built in at the factory to near 0%, at least it does so on pre '09 models. The taller tire also imprves turn-in, tracking and overall handling, IMO.
In fact, if you drop your front tire size down to a 140 it won't compromise your ABS and your machine will feel and handle as though it's 200 pounds lighter enabling handling (flickability) that is mond-boggling!
