The H2 needs to be as heavy as it is in order to be strong enough for its rated power output.
A ZX10R engine does not have enough strength margins to withstand being supercharged with adequate durability and longevity.
Everything in the load paths inside the H2 engine is stronger. Pistons, rods, crank, transmission, cases. There's more metal everywhere, because there HAS to be.
The airbox is metal instead of plastic. It's heavier - but it has to be that way, because it is now a pressure vessel.
It is a different bike from a ZX10R ... that's why I have one of each :badteeth:
I like this new sport-touring variant but I've already got too many bikes.
