You get 70 miles of range and that is without a powertank?
My personal record is
169.1mi and 2% SoC remaining. For reference that was 40mph or 45mph average speed and a drop in elevation of about 5800ft, and I'm about 180lbs plus I was carrying 30lbs or so of cargo. Yeah, ideal conditions for range but no powertank there.
More usual is like when I
rode 85.8mi and 19% SoC remaining, at 55mph carrying 35lbs of groceries. This tends to drop to 1mi range per percent SoC the faster I go towards 70mph. Faster than 70mph up to 100mph you could theorize that range drops to 1mi per two percent SoC but there's nowhere to legally go that fast around here.
I bought mine at a dealer in Reno after taxes for the same as MSRP, and that was with the dealer selling essentially at their cost.
If you're 220lbs rider no question go for the 2017 SR or DSR. I think the 2016 has just enough torque until I'm carrying 40lbs of groceries in the top case, and then it's a little noticeable!
When deciding SR or DSR it depends how long you are, all other things are close to equal. I cannot flat foot the DSR in flat shoes but I got some boots with higher arch support and it's close enough for me. The SR is very natural to ride hands-off compared to the DSR which of course has a higher center of mass. I wouldn't dare take my hands off the bars on a DSR in a corner. Comparing the clearances of the SR and DSR where I ride in the mountains and off-road trails, I am glad I went with the DSR for doing things like riding up or down a set of stairs. You can do these things on an SR but I would worry about the clearances. I rode a loaner 2016 S model for awhile and that's how I know the differences.
