I'm not so sure that you can shift quicker without the clutch than with. You have to back off the throttle, and move the shift lever to make a clutch-less shift don't you?
From an article I just read on shifting: https://www.revzilla.com/common-tread/ho...motorcycle
"Clutchless shifting
You know how we said the clutch acts to disengage the crankshaft from the transmission to unload the gears and allow them to shift positions? Well that same unloading effect can be achieved by quickly and briefly rolling the gas off and then back on again. In that instant right after you air the throttle, the transmission is unloaded. If you time your upshift to coincide with that momentary unloading of the transmission, the bike can be shifted up up into the next gear. No clutch required. "
In that same time it takes to roll the throttle off and back on you could fan the clutch blade and make the shift without even rolling off the throttle if desired.
Now the new speed shifters you shift without backing off the throttle so they are quicker than an old time clutch-less shift I would think, with less risk of damage to the trans
That said, I just don't see the point of either method for riding on the street. Maybe on a race track where tenths of a second matter.
Oh and the DCT trans is even quicker at shifting yet, all controlled by computer, quickly and seamlessly with no possible damage to any transmission parts
