I don't see where this will be much different than the "new" F6B Goldwing. Looks to be the same engine, a good one, but not nearly as fast as an R3R.
The Wing does have great handling, likely better than the Rocket; however, its ergonomics are quirky with feet tucked way back on account of the engine desiogn. Shifting can be quirky as well dur to this location. 17 inch rear wheel with a 19 inch front wheel, wow that's getting moto-cross size! ABS optional? BS on that.
Likely shall be a very nice motor; but, performance wise definitely way behind the Rocket.
Just my first blush thoughts,
