The failing weather reminds us we're fast approaching the end of another year, but Zero Motorcycles wants to brighten our day with the announcement of its 2013 all-electric line-up. Immediately noticeable are the harder lines and healthy dose of matt black on the frames of the Zero S, DS, XU and MX refreshes. New to the team is the FX "Stealth Fighter" (pictured above), touting the fastest acceleration of any Zero moto to date and taking design cues from the late Zero X, which has been removed from the roster. As well as aesthetic improvements to the bikes, each Z-Force motor should produce up to 125% more power than previous iterations, and an optional CHAdeMO charging accessory will juice you up in around an hour. Companion iPhone and Android apps will also be available, allowing you to customize your ride's performance and review other info. The class of 2013 will be hitting retailers throughout January and February, with MSRPs of the basic spec models running from $7,995 to $13,995, depending on your wants and needs.
