The H2SX’s broader spread of
power will tear your head off at
4000rpm, and really, really tear
your head off at 6000rpm.
But in a nice, linear fashion
The impeller blades on the superchoofer (which
still spins at 9.2 times the rpm of the crank) have
also been reworked. The shape and angles have
been changed so you have better pressure at
lower rpm. And to better fill those cylinders with
explosions, the cams have a lesser duration and
overlap.
The result?
Well, instead of tearing your head off when the
tacho hits 7500rpm (as on the H2), the H2SX’s
broader spread of power will tear your head
off at 4000rpm, and really, really tear your head
off at 6000rpm. But in a nice, linear fashion.
So getting on the gas and firing it hard out of a
corner does not require huge amounts of right-
hand finesse.
And it just seems to accelerate faster and
102 KIWI RIDER
harder as the tacho climbs up towards the soft-
limiter at 12,000rpm.
It really is breathtaking the way it does this, and
you really do have to remember to breathe.
Acceleration redefined…hell, reinvented
actually, I swear, your honour. It was a science
experiment.
Electronics have also been enhanced on the SX.
So enhanced…
The Bosch IMU works in five axes, while there is
a sixth yaw axis (rotation around a vertical axis),
which Kawa’s own software deals with.
Cornering ABS assistance now happens via
Kawasaki’s Intelligent Braking System (KIBS),
which is informed by a new ride-by-wire throttle
set-up.
