Zero Motorcycles continues to upgrade its model line-up, with the 2013 Zero Motorcycles bikes getting a motor and battery upgrade. Offering bikes now in 8.5 & 11.4 kWh packages, Zero claims city mileage ranges to be 103 & 137 miles, respectively. The motors on the Zero S, Zero DS, and Zero MX have been bumped up to 54hp spec, the Zero XU retains its 27/28hp configuration, and the new Zero FX gets a 44hp lump.

The big addition to the family is the 2013 Zero FX (pictured above), which follows the lines of the Zero DS dual-sport, but uses the same chassis as found on the MX. The Zero FX appears to be the more off-road capable version of the Zero DS. While the DS will have 8.5 & 11.4 kWh options for its battery packs, the Zero FX will come with only 2.8 & 5.7 kWh unit options — the same as the Zero XU and Zero MX. Pricing on the Zero FX starts at $9,495.

The added battery and power boosts should help keep Zero Motorcycles in check with Brammo, which is set to finally bring its Brammo Empulse R street bike to market later this year. With 2013 rumored to have a “Brammo Killer” in the line-up, we’re not quite sure if the Zero S design lives up to the hype, even with its upgraded power train, but considering the sales figures between the two companies, we might be wrong on that assessment. Photos after the jump.

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.

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).

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.

While still maintaining the product line’s general aesthetic from its previous generations, Zero Motorcycles has refined and polished its electric motorcycles for 2012. This is primarily due to the Zero’s limited amount of time to further develop its 2011 models for the 2012 model year (roughly nine months says the Californian company), but still Zero has been able to revise most of the Zero S’s components to warrant this year’s models to be visually and functionally set apart from its predecessors.

This bodes well for Zero Motorcycles, because bluntly, the startup has had extremely unrefined and unpolished motorcycles from its inception to the 2011 model year (if you heard otherwise from somewhere else, they were trying to sell you something). Walking up to the 2012 Zero S, it is immediately clear that the electric motorcycle has been touched by people who understand motorcycles. Gone are the on/off switches marked in Sharpie (I wish I was making this up), though you’d be hard-pressed to find top-shelf components on the Zero line. This makes for a mixed response regarding the bike, from a visual perspective.

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

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.

As we get ready for TTXGP’s first race in the United States this weekend (and apparently the AMA is racing with them too, who knew?), more details are emerging about what we can expect from Sunday’s race. Our operatives caught Team ZeroAgni and K² out at Thunderhill last week, and saw a modified Zero S (K²’s entry), and a GSX-R piloted by Shawn Higbee taking laps around the track. With the GSX-R clearly not TTXGP legal, we were left to speculate what AMA privateer Higbee would be riding at Infineon, and now we know: it’s the inaugural TTXGP winning bike from Agni Motors (you can see the bike re-painted above, with it’s noticeable “tank-plank” protruding).

UPDATE: It looks like Zero is using Team Agni’s GSX-R based electric motorcycle, which won the inaugural TTXGP last year at the Isle of Man. Picture in the comments posted by our very own John Adamo (skadamo).

They were all at Thunderhill Park Raceway yesterday testing for Team ZeroAgni, that’s what. With a Suzuki GSX-R (600 we’re assuming, but impossible to tell) and a modified Zero S that was sporting the K² logo, the team from Santa Cruz was out getting their lean on with some special help from Shawn Higbee, of AMA privateer fame. The assumption from these findings is that Zero Motorcycles was out pacing the K² Zero S, against the sportbike to see how the two compare. We can only assume that the added presence of Buell-tour-de-force Higbee means the AMA rider has been tapped to pilot ZeroAgni’s race bike at Infineon on May 16th.

UPDATE: Neal Saiki comments about using the Mavizen chassis.

Zero Motorcycles has announced their entry into the 2010 TTXGP series, where they will race against Team Agni, and competitors using the CRP Racing and Mavizen platforms. Early reports peg Zero as also using a Mavizen TTX02 platform, essentially a KTM RC8 chassis gutted of its ICE components. Despite using the Mavizen/KTM chassis, the race bike will be powered by Zero’s Z-Force battery packs and motors.
