Blitz11 speaks of side loading and how street bikes don't have to deal with them. Make sense to me, if the GS and/or the Tenere are used in their designed manner, they will see plenty of side loading. If the single swing arm does not like that....it would explain the failures. I was always told that the paralever was to reduce shaft rise. I believed it because my RT1150P would squat under acceleration. The ST1300PA would exhibit a small amount of shaft rise occasionally. Neither bike changed the way that I drove. I did like the easier tire change. I did NOT like the shaft failures. I do not know if the single swing arm was the cause though. The Tenere does seem to be built heavier; the rear hub even has cooling fins!
