Recall: 2012 Zero Motorcycles S & DS

By 3 Comments

Zero Motorcycles has issued a recall for 2012 Zero S & 2012 Zero DS electric motorcycles. Affecting 315 units, the recall is for a motor encoder position signal, which may drift over the course of the motorcycle’s use. If the signal drifts outside of the given parameters, the motor controller may shut off, resulting in the Zero inadvertently losing power.

Obviously, if the motor cuts out power unexpectedly, it could result in a loss of control of the motorcycle, which could lead to a crash for the rider. Zero Motorcycles will notify affected owners, and Zero dealers will reprogram the motorcycle’s motor controller free of charge. The safety recall is expected to begin on September 24, 2012.

Concerned owners may contact Zero Motorcycles at 1-888-786-9376, As always the NHTSA is available at 1-888-327-4236 and safercar.gov.

Recall: Weatherproofing Lacking on 2012 Zero Motorcycles

By 4 Comments

Things aren’t going so well for Zero Motorcycles, as the electric motorcycle manufacturer has submitted a second recall to the NHTSA, this one for the 2012 model line-up. Recalling 254 units because of insufficient weatherproofing, the motorcycles may be subject to an electrical short inside the battery management system (BMS) during wet conditions. A short-circuit could cause the electric motorcycle to cut power, which could potentially cause an accident (the recall notice from the NHTSA says nothing about possibility of electrocution).

Recall: 2011 & 2012 Zero Motorcycles

By 1 Comment

Zero Motorcycles has submitted a recall with the NHTSA that includes units from its entire line-up, built for the 2011 & 2012 model years. The issue stems from a faulty brake light switch, which may not illuminate the rear brake light when the front brake lever is pressed without strong force.

The recall affects 450 units of Zero Motorcycles’ on-road units, which includes the following machines: 2011-2012 Zero DS, 2011 Zero MXD, 2011-2012 Zero S, 2012 Zero X, 2011 Zero XD, 2011-2012 Zero XU. Because the brake light may not illuminate while the motorcycles are under braking, Zero Motorcycles will recall the affected units starting around July 16th.

Recall: 2009-2010 Zero DS & Zero S

By 8 Comments

Zero Motorcycles is recalling 160 of its electric DS & S motorcycles for an issue with the front brake caliper. Because of the defect, owners may experience permanent deformation of their brake discs when subjected to high braking loads, which induce misalignment of the front brake pads with respect to the front brake rotor. Accordingly, misalignment of the brake pads in relation to the rotor may cause reduced front braking performance, which could lead to a possible crash and potential injury or death of the rider.

The pertinent models and build dates are as follows:

  • 2009 Zero S – September 2, 2009 through December 22, 2009
  • 2009 Zero DS – July 27, 2009 through December 28, 2009
  • 2010 Zero S – February 1, 2010 through March 31, 2011
  • 2010 Zero DS – January 20, 2010 through March 31, 2011

2011 Zero Motorcycles Get Quick-Charge Option and More

By 5 Comments

Fresh off its latest $2 million fundraiser, we get more news from Zero Motorcycles, as the Santa Cruz, CA company has released its 2011 line of electric motorcycles. Immediately noticeable is new livery and color schemes, but we think it’s the technical changes that will get people truly excited. Most prominant in the model year unveiling is the fact that every bike in Zero’s 2011 line-up can have a quick-charge option installed.

A major highlight, the quick-charge system will allow Zero Motorcycles with the add-on feature to be charged in nearly half the time of the standard version. Also a part of this technology’s allure is the ability for Zero Motorcycles to be charged off the J1772 public charging stations, which municipalities are starting to install in public parking spots.

Zero Expands Lineup With Zero DS Dual Sport

By 7 Comments

Zero Motorcycles recently introduced a 4th model to their electric motorcycle line up. The Zero DS is a dual-sport bike built on the Zero S supermoto platform. The front suspension of the DS gains 2″ of travel over the S for a total of 10”, while rear travel remains unchanged at 9”. A 50/50 street/dirt tire is fitted to the 17″ front rim and a 90/10 street/dirt tire is fitted to the 16″ rear. This is an unusual tire combination for a production dual sport but the semi-aggressive front is a welcomed change from the tires found on most dual-sports, which are more suited to street than dirt use.
