One of the Zero engineers posted this youtube video from the recent TTXGP race at Infineon Raceway. He wrote the following comment on the posting, and refers to the troubles faced by Lightning and Brammo that I documented earlier.
This is video from the 2012 Sears Point Infinion raceway TTXGP. The onboard footage is from Martin Szwarc, who won 1st place in the eSuperStock class, as well as 1st place overall. (Other teams struggled with reliability issues and couldn't finish 2 races without a DNF)
The whole event went amazingly smooth, no issues at all with the 4 Zero ZF-9 bikes entered. It's amazing that the bikes handle well enough to perform like this right off the showroom floor, just add race tires. We used Pirelli Supercorsa tires, which are both DOT legal and stick very well on the track.
