How do they get 25 HP out of the 250 cc RX3 and only 16 out of the 230 cc on the TT250?

Really curious about this!

Thanks
It's all in the head and cam. The 230 uses a single cam with a single lobe to operate both valves. The RX3 engine uses a double lobe cam with four valves. More air and fuel in more power out.
