I've got them on some other bikes but I don't think they'd offer any huge advantage on a VMAX. If and when I do the BST wheels I'll probably go the ceramic bearing route because, well, what's another few hundred dollars when you're buying carbon fiber wheels.
Lots of drag and top speed guys run them, including in the engine, but unless you've got a compelling need to replace bad wheel bearings and need to have the coolest bearings possible, I don't think I'd be in a hurry to go that route.
