It could produce more power if that's what they were chasing, like Kawasaki, but its not ;
"Honda, however, is using a different type of supercharger entirely. It’s a twin-screw design, which is a type of positive-displacement supercharger. Unlike a centrifugal blower, a positive-displacement supercharger moves a fixed amount of air with each rotation, and since it’s geared from the crankshaft, that means you basically get the same amount of boost pressure delivered to the cylinders all the way from idle to the redline.It’s the sort of supercharger that drag racers use, as it provides close to maximum boost all the way through the rev range. A centrifugal blower might make a bit more peak boost overall as you get near the rev limiter – hence Kawasaki’s choice when looking to make a supercharged superbike – but for an adventure bike like the Africa Twin, a flat, fat torque curve is what’s needed, making the twin-screw supercharger a better option."
it seemed likely that we might see more smaller / mid displacement supercharged engines so its an odd bike for Honda to start with for sure.
