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

Zero Motorcycles has quietly announced some interesting news: that Mark Blackwell, V.P. of Motorcycles at Polaris Industries, will be joining the electric motorcycle company’s Board of Directors. With a plethora of reasons as to why an industry veteran like Blackwell would join Zero’s board, it’s been no secret that the Scotts Valley company has been collecting seasoned industry professionals like pokemon characters, seemingly building a brain trust of people who actually know how to run a motorcycle company.

Blackwell’s addition to Zero is interesting because it could signal a relationship with the Polaris V.P. that goes beyond merely an advisory/visionary position, which is the core responsibility of a companies board. The timing is interesting as well, as Polaris has been on a buying spree, first acquiring the original American motorcycle company brand: Indian Motorcycles, and a few days later electric car manufacturer GEM. With a Polaris executive sitting on Zero’s board almost immediately after these aquisitions, one has to wonder if this isn’t a precursor to some sort of larger arrangement between the two companies.

The news coming out of the Santa Cruz area today is that there’s been a management shake-up at Zero Motorcycles, as multiple people at the top of the company’s leadership have been given pink slips, including company Founder & CTO Neal Saiki. Recently talking to PlugBike.com‘s John Adamo, Zero Motorcycles CEO Gene Banman denied that Saiki had been let go from the company, saying that Saiki’s absence at the company was due to his child’s recent birth and Saiki’s desire to spend time with his newborn.

However multiple sources close to the company have confirmed to Asphalt & Rubber that Neal Saiki was a part of a larger management shake-up that was precipitated by the company’s lead investor. With many of the terminations expected to be finalized next month, and spanning more than one division at the California-based startup, there appears to be a considerable personnel and culture shift occurring at Zero at this point in time.

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.

Your favorite electric motorcycle company from the sunny beach town of Santa Cruz is about to get some more international appeal, as Zero Motorcycles has announced today that it will expand its dealer network south of the border and into Mexico. Signing local distributor Dofesa Aventura (the Mexican distributor for Polaris and its Victory motorcycle brand), Zero’s S and DS models are immediately available for demo rides, and the rest of Zero’s line-up is expected to be available in the coming weeks.

This move continues Zero’s agressive international presence, as the brand already entered the European market back in 2008, and completes Zero’s presence in North America as Zero Motorcycles are already available in the United States and Canada as well.

Zero Motorcycles may not be amassing as large of a war chest as Brammo, but the Santa Cruz company is getting a lot of free money and help from its local governments. Scoring a $177,906 grant (free, as in beer, money) from the Monterey Bay Unified Air Pollution Control District (MBUAPCD), Zero intends to use the money to continue its R&D efforts in developing its drivetrain components. This money will be added to the $900,000 grant that the California Energy Commission gave Zero last much, whose funds were then matched by the City of Santa Cruz and other investors.

Don’t call him a custom motorcycle builder, Shinya Kimura is really more of any artist whose medium is on two-wheels (among other formats). In an industry that centers around products that should resonate with their owners, Kimura finds a way to put more soul into metal than just about anyone else we know. Check out after the jump this unlisted YouTube video by Henrik Hanssen, which shows Kimura and his work from his shop Chabott Engineering.

Qualifying ended today at Infineon Raceway, with nearly all the riders improving on their times in the day’s later qualifying session. While all the entrants will get to compete in the race regardless of whether or not they qualify, the two outings for Saturday gave us a preview as to what we can expect on Sunday’s race. As we’ve mentioned before, the Zero/Agni motorcycle looked very strong with Shawn Higbee at the helm.

Also looking confident was the “flying banana” fielded by Lightning Motors. Piloted by Michael Barnes, Barney took the yellow lightning machine around the course at a pace that was just seconds off what Higbee & Co. were lapping. We know the yellow bike has a lot of power on-board, and could give Zero a run for their money if they’ve been sand-bagging it during the practice sessions. Finishing out the top three was Thad Wolff and his stunning Norton, which blended a little bit of old with new with his streamlined retro bike chassis.

TTXGP hit American soil here at Infineon Raceway today, with two zero-emission practice sessions under its belt for the day. Although dubbed an historic moment, today’s big winner probably wasn’t the sport of electric motorcycle racing, despite ZeroAgni put on a strong performance during the practice sessions. At the helm of the ZeroAgni bike was AMA privateer Shawn Higbee, who looked the part on the former Team Agni Isle of Man bike. Higbee was carrying tons of corner speed, and was the only electric sportbike rider to lap the course at near sportbike speed, and to really go the distance lap-wise.

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).
