I came off a 12 Ultra Limited to a 16 RGU and will not go back. I now have a 19 RGU. It takes some time getting used to the frame mounted fairing and the distance between you and the inner fairing. I have absolutely no regrets and again, no plans to back to a batwing fairing.
The question is, "is the 114 that much better than the 103" ...I own a 15 LTD with a 103 which I love, and have ridden my fair share of 114-powered LTD's, SG's and RG's and can say there is no comparison between the 2 motors...the 114 is so much better than the 103 (stock to stock) all the way from low RPM to redline!
Much better, easier to use, user interface (GUI) coupled with a much faster processor...
go tap on the screen in the dealer, and you can tell the GUI has much less latency, it's awesome, just moving between screens is much quicker, and doing stuff.
