Zero Motorcycles is recalling 254 of its 2012 all-electric motorcycles due to "insufficient weatherproofing" of the battery-powered bikes, according to a recall posted by the U.S. National Highway Traffic Safety Administration.

If recalled models of Zero S, Zero DS, Zero X, Zero XU, and Zero XU-LSM electric motorcycles from Zero are subjected to "wet conditions," the battery management system circuit board may short, leaving riders unexpectedly powerless and possibly in danger of a collision. (Update 7/16/12: Zero has informed us that it is not a problem with the batteries, but rather the circuit board.)

Zero also issued a recall on 2011 and 2012 models to address an issue with the front brake light switch. The brake light may not activate with a light or moderate brake application, and therefore not alert traffic to the slowing motorcycle.

Zero is expected to alert owners of the flawed motorcycles this month, instructing them to bring the motorcycles to authorized dealers where repairs will be made free of charge.
