I own a 2011 Zero S which I love, but the stock mirrors do not extend out far enough. All I could see in the mirrors was my shoulders. Luckily, there was a good replacement that the dealer put on for me. The other thing on the 2011, and it appears to be true of the 2012 as well, is that if you need the lower seat, you may have a problem getting on and off...especially off cause the rear end sticks up considerably higher than the seat. I have a standard seat which is fine for me at 5'8", but I do have to do some considerable flexing to bring my leg over that raised back end. Then I look underneath it and see all that empty space and have to ask why they would design it that way? I do wish they would drop it an inch or two and still maintain the look. Some of us aren't getting any younger....I suspect a lot of us. Young kids won't be able to afford Zeros. They buy the Ninja.
Do the short-guy-shuffle:
Sidestand down, stand on left and right peg, swing right leg over bike, unclimb via left peg. Opposite for climbing about. After watching some of my dualsport buddies that were height challenged do this, it makes sense, especially off road or off camber situations.
