Do not start moving or race the engine immediately after starting it, even if the
engine is already warm. Run the engine for two or three minutes at idle speed to
give the oil a chance to work up into all the engine parts.
Just to be clear, I stated "as long as you're not going to drag race it right away". I do start the bike and let it run while I put on my gloves, sunglasses, turn on radar detector, etc. But if you've had your bike for any length of time, the internal parts are already coated with oil. The oil pump returns oil to every area almost immediately. As long as there's oil, no problem. If you ride off at a moderate pace nothing bad will ever happen to your bike. If you red line it on the way out of the parking lot, all bets are off. The internal fits on engines these days are very precise. There is a certain amount of warm up when everything cozies up to each other the way it's supposed to do, but at moderate loads and speeds, no problem.
I never start the bike without being on it, unless it's after an oil change or something when the bike is on the center stand.
