Zero DS review by Motorcycle.com
Motorcycle.com has published a test ride review of the 2012 ZF9 Zero DS model, including a video, a reasonably long article and a dyno chart. This review is a lot more balanced than the one done by another organization recently. Note that along the left-hand side of the page is an index, which provides a link to all of the other electric motorcycle reviews that they have performed in the past.
