it is a dry sump engine, which when shut off about a quart plus of oil drains back into the engine crankcase from the oil tank.
If you washed the bike, it probably had enough time to drain out of the tank into the crankcase.
If you have no oil puddles on the floor, today, the oil is still in the engine/oil tank.
The oil level check requires you to run the engine about a minute to pump the oil back into the tank before you check it. (check owners manual)
Go ahead and start it up, you may get some blue smoke out the exhaust in that first minute, than shut it down and check oil level.
