Well, I just can't resist "chiming in" ... and have to side with granpaul on this. Of the 8 Nortons I've owned since 1981 (3 850's and 5 750's) ... I would have to go with the MK III; never owned one of those yet. However, I don't plan on selling my 1973 750 (great runner) or my 1974 850 (currently being built). However, as L.A.B. states, it would be nice to to test ride both ... and see which one YOU prefer. ( But if ya got the money buy em' both ???) Cheers.
