I believe its 16 valves engine making it 4 valves per cylinder... The old i4 zx25 during the 90s is also 4 valves per cylinder, with the puny valve size they have notorious reputation of valve head snapped if not maintain properly. Your observation about tiered licensing is correct. It's also super popular in my country where our license are classed based on CC, Below 250cc, 250cc - 500cc, and above 500cc. But most of the young boys here wouldn't be able to afford the new ZX25R.
Its interesting with only 250cc the bike is making as much as my 2 cylinder 650cc ninja. My country kawasaki dealers had been bombarded with request to bring the i4 250cc in. But how many people will actually really buy it once its in is another story....

Should be really popular in places with tiered licensing. When I lived in Japan, there were a lot of 18 year old boys riding 100cc machines styled like WorldSBK.
