Does the ZX12 Race have a carb with restrictors?

On a Austrian site I saw a ZX12 Sport (#201000) and a ZX12 Race(#201001).... the only difference is the carb according to the specs: the Race has a carb with Wechseleinsatz...the exchangable restrictor.

On the top of this site you can see a pic with all kind of parts: also a carb with restrictors.

On myTSN there is no product#201000.
The ZX12 on myTSN has a carb with no restrictor....
Confusing!

I found the Mega tuned pipe for a ZX12 in a shop here ( The Border Online), but nothing on MyTSN....no part #203004.....
