Not a silly question, bgd8rd. I asked the tech when the same thing when he gave me my operational walkthrough. He told me I could rinse the bike with a low pressure (shower or flood setting) garden hose, but don't spray it with full or high pressure. I've been doing so since with no ill effects. I do try to keep the controls and instruments dry, but if they do get wet, I just dry them with a soft towel. A splash of water won't hurt your bike (after all, it was designed to be able to operate in the rain), but the high pressure of a car was could get water in places it shouldn't be.
