Not sure, but for me the original Kat was the beast in the then Suzuki stable, the 'new' Kat is just a rebadged/refaired GSX-S from my understanding - sits far below the GSX-R and Hayabusa, so not really sure how it is actually a Kat.
That said, I think its a pretty cool looking bike - have only seen one in flesh once and kinda liked it.
