This is true. Usually when someone needs a stronger clutch, it's because they've increased their engine's performance far beyond it's stock counterpart. At such a point, the engine will overpower the stock clutch, naturally. So you've got a couple options... 1) Run a larger diameter clutch, 2) Use a Multidisk clutch pack, or 3) use a compound that has a higher coefficient of friction.
#1 Would be a great choice, but then we would need to change the transmission in order to place the starter out farther, and that would be a huge job requiring many custom parts.
#2 Is a great choice since you can maintain a smaller rotational mass while centering the weight at a smaller diameter. You could use 3 or 4 disks that have a smaller OD and less contact surface per disk, but multiplied would give more frictional surface total. But this requires either a new custom flywheel, or modifications to a stock flywheel, and would be at least $800 to get done.
#3 This is the only reasonable choice for the big power builder who can not afford the thousand dollars or so for the other options, since this way is just $275 or so.
Well, with that said, I am sure this is common sense and I dont mean to be a jackass with this, but my point is that the majority of the customers who are buying this clutch do not have 200+ horsepower engines, they just simply want a clutch that grabs much better than their stock clutch.
So, with a stock engine, I would imagine that it would take some time destroy a flywheel with this higher frictional ceramic clutch disk. Sure, with an engine with 200+ HP, yes, it's going to tear up the flywheel, but for the average 22R or 22R-E, this is an excellent clutch for someone who wants the highest level or clutch performance without having to pay $800 something for the alternatives. I am sure that the average engine with this clutch and stock flywheel combo will last for many many miles to come-
