You seem to want to argue. Whereas I'm just giving an opinion to a guy I've 'known' online for 15 or so years.
I've ridden all of the tires I've mentioned, under the same conditions, so I can contrast and compare them on the same bike in question in this thread. I have no allegiance to any particular brand, no particular manufacturer is sponsoring me for tires on my streetbikes.
If you like the Shinko that fits your 25 rwhp scooter, then congratulations, you have found your tire.
However, on a 160 rwhp (in stock configuration) Sportbike, all of the Shinko offerings that will fit the bike, are just mediocre in all aspects, compared to their direct competitors. Except for the Drag Radial that does offer good grip for that specific use.
