Everything is sealed, waters not going to get into the bearings, engine, forks, etc. Unless a seal is bad, then any water (fresh or salt) is going to cause the same problem.
Now if you submerse the bike (meaning the whole bike goes under water), water can get into your engine thorough the exhaust, intake, crank case vents, etc and that will make a mess of the inside.
Just wash it off, and oil the chain. And don't high pressure spray it, that can cause damage even if you live in the desert. High pressure water can and will be forced past orings, seals, gaskets, etc.
