It is perfectly acceptable to turn off the choke and start the bike. The engine will not be put under any additional stress. However, revving the engine after the bike has warmed up can put additional stress on it, since the oil is still cold and the lubrication isn’t as good.

Over-doing the choke can cause engine wear and fuel waste. This can also be harmful to the environment. On a cold day, an engine may need more fuel to start - this can cause the mixture to be 'richer'. This is what the choke does.
