Re: I kind of like these aftermarket fairings...
I'm not sure how relevant this is, but after replacing the fairings on my old CBR400RR with a chinese aftermarket set, the only serious issue I've had (apart from them not lining up very well, or fading in sunlight), was that the front fender soon (as in, after a year or so) broke in half. The part was much more thin and flexible than the OEM part, which had suvived for nearly 20 years intact by that time, and which provided at least a couple of years of further service, after I put it back on. I suspect the flexibility allowed it to flap significantly against the wind current, until it cracked due to fatigue.
