The engine of the Honda CBR300R is not created / geared for a better top speed compared to the Honda CBR250R. What has changed is that the new Honda CS300RE engine takes less time to get to top speed, the 286cc (37cc bigger than the 249cc Honda CBR250R) engine gives that extra push over the Honda CBR250R (CS250RE) engine.
If somebody would change the final drive gear (transmission to rear wheel, by sprockets) they would probably get a higher top speed.
Sure, it's possible that the Honda CBR300R go's faster than 160km/h, people change the exhaust pipe or have less body weight… I'm sure that if a Thai with a weight of 45kg rides the CBR300R it will go faster compared to 100kg…
