Torque Problem

I just bought some new technics 1210 m5g turntables .i have 2 1200 mk2s but they were getting pretty old so i bought the m5gs The problem i notice is the torque on these m5gs they dont seem to be as strong as my old mk2s the platter is alot eazyer to stop on the m5gs and not much hand pressure to stop the platter even with a slipmat i thought the motor might be defective somehow but both of them have this problem someone told me that they need to be broken in is this true? could it be this new digital pitch ?can anybody give me some ideas.. One more thing my old mk2s work better with serato than my new ones
