Wow. We seem to go through a sky falling stage.

Everyone needs to stop thinking and get back on their bikes.
You and science don't get along, do you? Keep thinking, it's what humans should be doing.

The engine is different how? Pull the parts list and look, just the starting mechanism changes to a larger one because a smaller one would overheat, and wear mechanically at a rate leading to premature failure. Changing that is a net sum gain.

In car engines they use advanced bearings, but I believe here they're the same as non-start-stop to keep the cost down. There will be greater wear even when advanced bearings are used, physics isn't circumvented.

There are benefits to stop-start technology, but also negatives. It's irrational to ignore the negatives because you don't like them. The question is, when do the benefits of stop-start technology outweigh the costs?

The answer is "rarely." We know this because if it was "usually" consumers would want it in order to save lots of money; instead it must be forced on people via regulations so special interests can profit at consumer expense. Although that's not always the case in every instance, in this case real-world testing proves the savings in scooters is negligible and far outweighed by the initial purchase cost. The cost in other areas is only later appearant.

The engine is different how?

The main difference is that when you start the scooter Honda with start/stop exhaust valve piston system open or partially open as you spin the flywheel, and does not, shock loads on crankshaft bearings and other engine parts. That is like when you run the engine without the spark plugs. Details about this system is available on the official website of Honda and even on this site http://www.hondapcx.org link to give now cannot.
Compare the starting motor with a compression of 11 atmospheres or close to zero, what is the rolling resistance or spinning parts of the engine?
Metal parts not in contact with such a "surge" of starting the engine. Honda engineers think easily calculated to durability.
