Differnce in front hubs?

Are there diffences between the front hubs for the 1150GS with Brembo brakes and BMW (Servo assist) brakes?  I've got a "new" bike with the BMW brakes.  The ABS ring is different from the Brembo's set.  I've got an extra set of wheels that I used on the previous one, now I want to change the wheels, one for onroad and one for offroad.  When I fit the older wheel, it doesn't turn, its stiff.  It worked 100% on the previous bike.
