Technically there is a neutral between each gear and if ou are lazy at shifting, it's possible to get into neutral between each gear. at some bikes it's easier, on some bikes its nearly impossible. but, it's the kind of working of a manual transmission in bikes.Gatdammit, do you still miss 5th to 6th from time to time? After all the mods I have done, mudder spring kit, stiffer springs, billet pressure plate, factory pro ceramic detent kit, hydraulic actuation conversion, various shift levers, quick shifter and ultimately dry slipper conversion I still miss 5th to 6th sometimes if I'm being lazy.
With our Hypers it's quite easy and I managed to find neutral in various gear changes on my bike, not only between 5. and 6.
This has nothing to do with clutch, you can change many things with clutch, but you cannot change the internals of the gearbox and how it works.
