Definitely an unusual design. Maybe they're targeting april of 2012.
As a point of comparison, S1000RR costs £12000 in the UK, $14750 in the US. I would expect the £9,975 and £13,975 prices to be closer to $12-13k and $17-18k in the US, not the $16k and $22k a direct currency conversion indicates.
675 bhp per ton compares favorably to the lightest of the Empulses, the Empulse 6.0, which is 330 bhp per metric ton. That's somewhat optimistic; the battery packs are likely 5-6 kwh and 10-12 kwh, which means the quoted power (if Saietta S) is a 12-16C discharge or more. Perhaps the quoted power is only for the Saietta R.
They're at the London Motorcycle Show now, so hopefully we'll get some more information soon.
