Norwegian article: http://www.mc24.no/article.php?articleID=1931&categoryID=241 And a translation
It was shown at the EVS24 meeting currently happening in Stavanger Norway (hence the Norwegian article). The article says this new bike will be 74 volts rather than 48 volts, a 55 HP drive train,
Cost: 20-25,000 Euro (US$34,000 or so)
The article makes a comparison to the Zero SS due this fall as well. It's discussed in an article on HellForLeather: http://hellforleathermagazine.com/2009/05/zero-ss-electric-sportsbike-ar.html
Not much detail but sounds like more fairing and a higher top end speed.
