kjazz, I don't know of anyone making these for speedy, but I have ridden a 06 ZX6r with a slipper clutch and reverse shift pattern. It was on the street, and plus with the reverse shift pattern(I wasn't used to this at all! :hammer: ), I wasn't exactly bang'n downshifts, or would that be upshifts? :hammer: :-D Anyways, just more useless text from the cheapster, I have ridden with one, but didn't really git to try it out.
