While downshifting a motorcycle, why does the bike automatically slow down even though you need to blip the throttle and increase the rev before shifting?

Question

Seems counterintuitive

Unless i’m reading something wrong, you’re probably thinking about the engine brake. Some bikes have some pretty crazy compression, and if you downshift you’re going to be high in revs, but that’s just because you’re going fast in a lower gear and the speed itself is turning the engine, and with high compression you’ll slow down a good bit. I would just time my downshifts and not even have to use my brakes often.
