Got my SR/F Premium on Monday, Traded my 2016 DSR for it. Some initial observations/comparisons. First my power use on two commutes is about the same as my DSR (13K vs 14.4K battery). Handling is way better on the SR/F, I am way more confident in turns. Highway is also night and day better on the SR/F, extra weight, size and more rubber, way less buffeting, even without a windscreen (my DSR had a Mad Stad Shield). I like the SR/F seat better than the Corbin or Stock seats on the DSR on the commute. I think acceleration feels similar between the two. I never really found the DSR lacking there, and the additional weight on the SR/F seems to somewhat minimize the feel of the extra torque (but there is more than enough!). I did not realize I needed cruise control, but I do, I used it a bunch on my first two commutes (100mi round trip). So far, very, very happy with the trade offs, I never rode in the dirt anyway with the DSR, and with traction control, gravel should not be a problem on the SR/F and that's about as far as I go.
Oh, and I was surprised that the riding position on the SR/F has not bothered me at all, I was concerned that the forward lean and extra leg tuck would bother me, but nope, at least not yet. I tend to have problems with my hands going to sleep on the DSR, I've not noticed that problem yet with the SR/F. I like the lower seating position as well on the SR/F, my feet are really solid on the ground on both sides flat footed, it feels good. I am 6'1" and on the DSR I always had a little bend on the angles when having both feet down at a stop.
I love this bike.
