That figure of 1000 2012 Zeros sold seems kind of high to me, unless most of the sales are to various government agencies that would not be posting about their experiences on message boards. I always felt that police, military, ranger and other patrol services seemed like the perfect market for selling lots of electric motorcycles. Fleet sales are a lot easier and more profitable than selling to one customer at a time.
If most 2012 Zero owners visit this board and are reporting running problems, than I would say that is a very small percentage of owners having issues and Zero motorcycles are very reliable - much more reliable than BMW motorcycles, as an example. (Consumer Reports surveyed thousands of motorcycle owners and recently reported that about 75% of BMW motorcycle owners reported that they had mechanical, electrical and other problems with their bikes.)
On the other hand, if only 25 or so 2012 owners post on this forum - where are the rest hiding out?
You would think that anyone buying a new electric motorcycle would want to learn as much as possible about their new vehicle and would want to connect with others who are similarly affected with the early-adopter disease.
That neat Zero owner spreadsheet created by benswing isn't quite up to 1000 owners yet.
BTW, I see that Terry (offthegrid) now has 25,000 miles on his much-modified 2012 Zero S. If he has had any "glitches" during his travels, I haven't heard about it. The only thing I have heard is that he blew up his motor when a bearing destructed. I think he is still using the same batteries that his bike came with, along with the new ones that he installed. Perhaps the failures and glitches that we have been hearing about are less of a design problem and more of a assembly or component issue?
