I've had a couple V45 Magnas and a V65 Magna, all with shaft drive. The drives were smooth n quiet. I did shear the splines on one of the 45's, but that bike had a hard life. I used to drag it a lot and generally beat the piss outta it. I had to push that bike 6 miles home.
The rear tires break loose pretty easy because when you get on the gas, the rear end lifts. The pinion gear is trying to "climb" the ring gear, which lifts the bike. I used to joke that I could smack the throttle on the 1100 and lift both wheels off the ground. The bike did look like it could, but in reality it never got off the ground
