No a PCV work. There is no way to safeguard your bike if you go in to deep of water. If you are looking to really put your bike through something like that you can only get a snorkel and exhaust extensions.
Most "sport" quads are not really subjected to the conditions to drown them so there is not much interest or market for snorkels. If they do make snorkel kits for any of them it would be no different than a 4x4 snorkel, Either some pcv or flex tubing.
