Power Commander is one brand. Personally I dont know if just quick upshift is worth spending the money as its easy to quick shift up without using clutch and done smoothly if you have a go.
My K12S likes 5000 -5500 RPM upshift no clutch and only move throttle a few degrees for fraction of a second.
I have Power Commander V with autotune AT200 (advertised for K13S) that allows quickshift unit fitting but still pondering what benefit I would get while my bike does quick upshift smoothly already.
Down with auto blip + slipper clutch would be another matter..........
