I don't see any mechanism to disengage the clutch when you step on the shift lever. That would be essential unless you want to come nearly to a stop every time you shift.

well once you shift i would imagine that the rpm will drop, which will disengage the clutch. im trying to figure this out.

Triumph used to offer (in the 1960's) Slick Shift, which dis-engaged the clutch just before the shift took place using only the shift lever. I didn't notice shifter movement being any greater than the normal transmission...ARH

shifting a MX or Enduro bike with out the clutch works fine the gear box still lasts as long as the motor.. just the action of cutting the throttle is enough to unload the gears enough to let it change.. ..

Honda had a centrifugal clutch in the early '80's ATC's. It extended the crankshaft on the right side, so the cover was deeper. The centrifugal clutch would subsequently activate the regular clutch, which was nearly identical to the clutch we have in our Honda clone China bikes. The gearbox can be whatever setup after that. Much like Pete indicated, all you did was back off the throttle to shift gears. When you came to a stop and let off the throttle, it would idle down and disengage so you didn't stall. Neat setup.

Every bike I have ever owned could be shifted without using the clutch. The only time the clutch was necessary was coming to a stop and starting from a stop. It's as simple as preloading the shifter, chopping the throttle, shift, and get back on the throttle. If done right, it's just as smooth or smoother than using the clutch. No, I don't do clutchless shifting all the time. Only when I am running hard in the mountains.

All the Honda Cub type bikes use the auto clutch setup. One of Mr Honda's criteria in designing the cub was the rider must be able to ride with one hand while holding onto something with the other. I believe some Honda quads use that type of clutch in an upright 200 or larger engines.
