Yeah, they don't remember the last setting you had, you just press it once and it goes on full power, and you press it more to lower it, though I've rarely put them on when I didn't need full power. They're a godsend in the rain too; my hands never stay wet because the grips dry my gloves as soon as the rain hits them :thumbup
Mine are mounted on the left mirror stalk, but you should get them mounted to the tank's fastening bolts just behind the headstock on the CB1000R (no space there, or bolts on my Hornet)
