I have owned many shaft drive motorcycles over the years and none of them have been maintenance FREE. Low maintenance yes, maintenance free no. The shaft itself may be good, but gearboxes and possibly U-joints need attention at some point. At 30,000 miles most riders won't touch it for many years anyway. BMW tried the sealed never needs maintenance rear drive once and it didn't work out well. If it moves sooner or later it is going to need attention of some type.
