The FXDR
used to be what they were pushing as the "performance" Harley except everyone hated it and the sales were garbage
The FXDR was there and
nobody touched it, and I don't blame them because it the was the worst bike I have ever ridden.
But anyway, back on topic. The new Low Rider S is a course correction away from the FXDR. So its now their performance Harley. And Even though I personally didn't like it, I can definitely see it doing well sales wise. Its definitely a step in the right direction. And honestly, I didn't really like the Dyna low rider S either, so it just is what it is.
And the Fat Boy
GOD, do I love that bike. I love it so much, that I almost got it instead of the low rider. Its the bike that inspired me to ride in the first place after watching Terminator 2 back in the day.
I can't speak for pre-2018 Fat boys since I haven't ridden them, but these new ones handle like a dream. No issues at all turning it and it feels like a beast as you are riding it. Strong and very satisfying power and its so comfortable to ride. I love that bike and I would love to own one at some point in my life.
