Um... NO. When executed correctly you don't need to use the clutch to upshift, on my track R1 and R6 I didn't even use the clutch to downshift, the clutch was never touched from the time I rolled off in 1st until I came to a full stop in 1st gear; it's all about learning the proper techniques and understanding how a motorcycle actually works. On my HD's I do use the clutch to up/downshift, but barely, I just break the lever with 2 fingers, but I'm preloading on both upshifts and rev-matched downshifts.
Pre-loading doesn't take much pressure at all, just enough to take up any slop and it certainly doesn't mean you're putting such a load on it that you'll damage anything
Give it a try, you'll be surprised how smooth it is...
This is from Lee Park's Total Control: " Press your foot up with just slightly less force than that needed to engage the next gear. Next, quickly roll off the throttle approximately 25 percent of its twisting range. When this happens, the torque force on the transmission will temporarily unload, and the preloaded shift lever will now snick into the next gear. For regular shifts at less than full throttle, a simultaneous, light stab of the clutch will help ease this process. For full-throttle 'speed shifting,' no clutch is necessary. In fact, it's actually harder on the transmission to use the clutch in this type of situation than to just let the loading forces do the job."

Tried it a few times, but electric or air shifters are the ticket for me, which actually cut the ignition (adjustable in milliseconds) to really take the load off the trans.
Despite what pre loaders would tell you, no one pre loading can keep up with me gear to gear, with my full electric shifter going thru the gears at 6-7 grand rpm load shifts on the trans. Happens too fast, especially the money gears-1st thru 3rd.
Take a walk along the pits of an Harley drag race gas class-all electric/air shifters.
Ask someone why they just don't speed shift (another word for pre load shifting), and prepare for some lol...

Different animal,, but on my 86 Gold Wing,, which are notorious for grinding into 2nd gear,, was told to pre load the shifter,, after I started doing that, no more grinding into second... Don't do it on my Harley, it shifts fine.

It's usually the same bikes that have the corners of the dog teeth rounded off.
