Damn. I had a vague awareness of the debris strike but knew nothing about the materials involved or the actual location of the hit. Not sure what I thought the debris was but I thought it had hit the ceramic tiles. Thanks for the link. PS: Hope you don't get a vacation for a non-motorcycle vid...too late to fix it now.
I raced a Triumph 675R with BST wheels for several years, no issues whatsoever. Do they change/improve the way the bike acts, absolutely. Acceleration, deceleration, handling, everything. They are the one modification you can make that improves every aspect of riding the bike. Is it necessary? No. Will it make you faster? Unlikely. If they were on a bike I was already buying, I would run the hell out of them...after having them inspected.
If you want to get down to actual facts regarding concerns over CF wheels being 'fragile' or 'brittle' you'd need a good finite element analysis model of the CF wheel and the OEM wheel to compare them. Without that, you're just guessing. That being said, CF by nature is much stronger for a given weight when manufactured properly. I wouldn't be concerned at all about running modern CF wheels from a big name manufacturer like BST, Dymag etc. That being said, for us small timers the more 'dangerous' thing about CF wheels is the difficulty in having them properly fracture tested after something like a hard impact or crash. If you cartwheel a stock bike and the wheels somehow come out unscathed, you probably just check them on the balancer and if they're round you keep using them. You'd check for fractures rather easily with just your eyes and maybe a flash-light or some UV dye. CF wheels are much more difficult to properly inspect for damage. So if you were going to be SUPER conservative after a big crash - you'd just replace the wheels if there was any signs of impacts at all. These are the types of things I would consider if I was using CF wheels on a motorcycle.
That's exactly it. It makes a noticeable difference in the way the bike acts; that doesn't necessarily mean the rider can/will take full advantage of it. If the rider still brakes and accelerates at the same points, or possibly even sooner due to a little extra speed at the braking marker, the lap times will not improve.
The GT500 (and I think the 350 optionally) come with CF wheels as well. When you see one in person its almost obligatory to give them a finger flick.
