The external ones are, the pic above is of the engine covers behind the fairings. All race bikes have them like this 
External one on the alternator. Not cheap, but exceptionally high quality, and replacement skid plates:
Plates also good for if the bike falls over, as mine has rather embarassingly!
err no they don’t :ermm:
In all the bsb garages I’ve been in for snapping for our galleries, they have. Perhaps not at the amateur level of racing where every penny counts.
I’ve had both carbon covers and NRC ones, crashing with both, and I can say that the carbon covers just don’t cut it, they wear out in one go, destroying the engine cover as well most times (but not holing it, importantly), whereas the NRC ones can take a lot of abuse. You can get two carbon covers for the price of one NRC cover though, so I see why they’re so popular.
The metal NRC covers are tough as lordy!. There’s one on my 750 and it’s taken some abuse but still good to go.
