Finally got everything together and rode my new DS to work. My commute is about 25 miles each way on the 405 freeway from Long Beach to West Los Angeles with a couple miles on city streets at each end.
I have the 9.4 battery pack.
On my commute to work I rode between 25 -55MPH with a stretch of about 2 miles at 75MPH.
The battery pack had 65% charge left on it at work when I plugged it in to charge.
On the way home there is no stretch of 75MPH and the average speed is a little less because traffic is usually worse on the way back (go figure).
The battery pack had 75% charge left when I got home.
As far as the ride. It was AWESOME! the delivery of power is so smooth and effortless. When I need to accelerate from 30-55MPH it feels like it happens almost instantly. I have never ridden an ICE motorcycle with gears but used to make this commute on a Vespa GTS250 which is twist and go. Although that was a pretty smooth ride, the power delivery is nowhere near the DS.
Other than an issue with the windscreen not staying in place, which is really a separate issue, the DS definitely lived up to my expectations.
