Factory Pro shift kit

Has anyone installed one on any bike, it replaces the shift star and dent behind the clutch reduces the space between 1st and 2nd gear and makes gear changes alot quicker and smoother, any advise would be good.

easy to fit, just need a rattle gun to get clutch basket out

Can someone please elaborate on what this device is?

Click on shift stars on the menu on the left hand side.

Would like to do it one day but dont have any real problems shifting since i got a quickshifter.

There velocity stacks rule though, awesome airbox sound on my racebike.
