Most modern shaft drive bikes don't suffer from the shaft jacking issues that used to be a common trait. Several brands use an anti-torque linkage (BMW, Guzzi, Concours), while some rely on the longest possible shaft (FJR, most shaft drive cruisers). From watching the videos and reading their claims, it appears the new VFR has it's own (new?) solution to prevent jacking by offsetting the shaft from the swingarm pivot.
