I'll forewarn you ahead of time . . . If you ride a 2017 DSR or SR, you'll be ruined for life, there is no turning back - the power and torque compared to a 2016 is like another bike all together.
I bought my 17 DSR only because it was electric and really not for the speed - however I wanted the latest refinements, i.e. Battery - New Motor - Big Ass Controller, etc. Rule of thumb on any electrics be it cars or bikes, you always want to get the latest technology!
The speed on my DSR is unbelievable, my friend has a Augusta Dragster RR and my Zero takes him out. While my racing days are pretty much over - lately I found a new enjoyment with this bike since it will out-run possibly 90% of the hot ICE rocket street bikes. I live 20 minutes from Suches, Ga, so this is bike country around here. When you pull up alone side them, most of the time they start snickering and smiling like most Harley guys do to other bikes. One smart ass even asked me where were my mufflers? What's funny is when the light turns green, or in the twisties here in Georgia, they never see it coming . . . while their grabbing gears, clutching and shifting and looking for me in their mirrors, my DSR rips right by them. LOL
Here's a few images of my "Sleeper" Good luck on your new venture!
