A screamer engine uses an even firing order as oposed to the 'big bang' engines the other manufacturers use, which have an uneven firing order.
The theory is that the big bang configuration is easier on the tyres and easier to ride due to the power dilivery characteristics. However kawasaki now think that modern electronics systems, i.e. traction control, open the door for a return to the screamer format.
Theres an interesting wee article here on the top gear site of all places:

It's still in testing at this stage. Not race ready.

Bloody cool sound though.

Just to add my $0.10... Ordinary road bikes are screamers, as are all World SBK bikes. The World SBK organisers banned the big-bang configuration when the manufacturers started to experiment with it.

The Ducati 800 is a screamer, I believe.

By the end of the 990 MotoGP era, all the bikes were big-bang. When I went to Philip Island MotoGP in 2005, the only screamer was the Harris V4 used by the WCM team (which folded shortly after). The difference was obvious from the exhaust sound: the WCM sounded like an ordinary multi-cylinder motorbike; the others sounded like something between a Harley and a very loud, high-revving 4-stroke lawnmower.

True, Hoppers' got heavily manicured eyebrows (alarming!) - but seems to have got the hang of that whole `cranking the turns properly' thing.
See you at the salon.
