No Question was the smoothest shifting I ever owned or test rode either one. My 2012 Cross Country gave me 80,000 Trouble Free Miles 50K of it Full Stage 2 but the Tranny Clunked like Hell from Day 1 and Never got better ..
The worst trans I ever experienced was a 2000 Harley Softail Standard that I rented for a week in San Diego. Every shift sounded like someone smacked the engine case with a 4 pound hammer. It was a brand new bike with 300 miles on it too. I wasn't sure it would last the week...
My friend, Turtle Joe, had a 2007 KP and that bike shifted like buttered glass.
His is the graphite/pearl white bike in the right lane here:
