I just got back from the Zero dealer meeting that was held in Monterey California and had the chance to try the new 2013 models. All I can say is WOW what a difference. Now you sit into the bike instead of sitting on top of the bike and the power is great. The frame on the S and DS has been redone which greatly helps with comfort while on the bike. On the FX, MX and XU they now have modular power packs for quick and easy battery changes plus of coarse all that extra power is alot of fun. Really they went over everything on all the models and I am glad to say this platform is here to stay for the next few years. I can't wait for my own 2013 Zero S to be delivered in the spring.
