The statement does not necessarily include drag bikes. If a drag bike gets enough air via a wheelie and comes down HARD, you can probably crack a wheel - whether it is Carbon Fiber or alloy. In fact, the big problem that the aftermarket for ZX-14s addresses is the cracking of a ZX-14 oilpan when a lowered ZX-14 comes down hard from a dragstrip launch wheelie. That is why those low profile oilpans exist.
BST tries to head off that problem by offering the heavier and stronger series of CF wheels for dragstrip use, but may dragracers either don't bother to find that out, or won't pay the extra cost, or simply think they want the lightest possible wheels regardless of vulnerability under abusive conditions.
The only BST wheel roadrace failure I have heard of was one many years ago where the rear suspension of the racer's bike suffered a failure while racing and caused one or more of the failed parts to collapse onto the rear wheel. Of course the rider claimed it was the wheel's fault, but experts who analyzed the failure disagreed.
There are always "stories" about exotic parts that riders claim failed unreasonably under normal use conditions. My favorite one is the one about the very lightweight rear sprocket that was clearly specified as being suitable for up to 100 hp (because it was made for nimbleness and low moment of inertia), that failed on a 200 hp racebike, and the rider involved attacked the sprocket manufacturer across the entire Internet when the sprocket fractured under that abuse (he had never read the specs in the ads for the sprocket), and a bunch of riders who also never bothered to check the specs spread the "fake news" across The Internet for YEARS after. I myself ran that sprocket with zero issues on a bike withIN the specs.
I'm sure a lot of riders and car owners also don't realize that Magnesium BURNS when exposed to flre, and then get pissed when underhood fire burns up a wheel.
And finally, every well written tire guide tells you that the best traction is achieved with a tire that has NO tread, but of course a no-tread tire can't handle rain. Nevertheless, it never occurs to many street riders that the DEPTH and DENSITY of tread is of course going to be somewhat proportional to the streetability of a tire (along with other important factors of course). So they don't buy Tire "A" because it has less tread depth and density than Tire "B", even though what they say they want is a "street legal race tire"!
Not enough buyers do proper research on their purchases. And when they buy the "wrong" product for their needs or desires, they blame the manufacturer.
Rook, if you are planning to supercharge or turbo the Busa, why not ask BST if your future plans are compatible with their wheels?
