I have Honda Dio 2015 Model. Yesterday, I kept the Choke ON while riding. I wanted to know what are the damages it probably causes to the engine? Does it have any after effects on the engine?

It will not damage the engine at all. All that will happen is that it will run richer, thus using more fuel.

If you did it for thousands of miles you'd probably end up with more deposits in the engine/exhaust, but even that is easy to sort.

The 'worst case scenario' that I can think of is this. Your spark plugs become fouled because the motor ran too rich and the bike doesn't start. You would need to remove the spark plugs and clean them with a carb or brake cleaner and re-install them. Don't worry about your vehicle. It's fine.

If it is a mixture richening device (rather than just a fast idle circuit used on most modern fuel injected vehicles), then fouled plugs, carbon build up (including on the lambda probe and cat), etc, would follow.

But a possibly bigger problem is washing the oil from the bores, greatly increasing engine cylinder wear, and some fuel getting past the rings to dilute the oil.

Of these the only one I would really worry about from a short 1 off ride would be the spark plugs and a quick thrash ("Italian Tune Up") will probably clean those out.
