From Superbike Magazine:
"Having dominated not only 2005 with the K5 GSXR-1000, but laughed in the face of its rivals' revisions in 2006, you could argue that Suzuki could have rested on plump laurels in 2007. But GSXR project leader Hirosio Lio and his swarm of worker bees have been busy redefining the leading edge in the class. In each of its three previous incarnations the GSXR-1000 has simply kicked ass, and the K7 version looks in prime position to do just that again. Already possessing a svelte body and killer motor, Suzuki has thrown a hell of a lot technology at the GSXR rather than upset the current applecart.
Different engine maps are common on race machinery and can enable a rider to adapt to different conditions, such as wet or cooked tires, but this tecnology has yet to filter down to road machinery. Until now. Position one on the switch gets you pure, unadulterated, firebreathing 184 bhp (up 6bhp from the K6 bike). Position two softens the power to around 150bhp, call it an autumn setting, while position three cuts the bike to around 120bhp for a proper 'wet' setting. Engine mapping and fuel injection changes will control the power differentials ratrher than any clever variable valve timing or the like.
The wet setting remains constant, while setting two jumps to full power on the application of full power. Funnily enough, these settings makes the GSXR1000 not only a litre bike sportsbike, but also a GSXR750 and 600 in one stunning package."
Neat. Three bikes for the price of one... hadn't thought about that before.

I'm more interested in getting a 05/06 1000 again, though. That bike and I just "clicked." The 750 just laughs at me and tries to suck me into corners faster and faster... then laughs some more.
