One of the stars of the show at the EICMA show in Milan this year is
the 2018 Kawasaki H2 SX, Kawasaki’s supercharged superbike now tamed for
sports-touring duties. More than just a model make-over, the H2 SX comes with a
revised frame, a new engine and a riding position halfway between the ZZR1400
and Z1000 SX.
There are two versions of the H2 SX, the base model
and the SE, which both carry the same four-cylinder, liquid-cooled, supercharged
power plant mated to a six-speed gearbox. However, the H2 SX comes with an
extensively redesigned engine, with enough changes made to call it entirely
new.
The supercharger impeller and intake system are
completely reworked, with new pistons, cylinder head, cylinder, crankshaft and
camshafts. Other all-new items include the throttle bodies and exhaust system,
now 3 kg lighter, and the gear ratios have been revised to suit sports-touring
use.
Power has dropped to 197 hp, but mid-range torque
has been punched up to suit the SX’s role as a highway mile-muncher. With the
redesigned intake and new throttle bodies, the H2 SX boasts of better fuel
mileage, which means the 19-litre fuel tank should give more distance compared
to the sports-oriented H2 and H2R.
Seating is now a two-seat affair, with the rear
passenger given a wider and comfortable seat, while the rider gets more padding
for extra comfort. There are two optional seats available – a comfort seat with
more padding that offers a relaxed knee bend, and a low seat that drops the
rider 15 mm closer to the ground.
Braking for the H2 SX is done by Brembo, using the
top-of-the-line M50 callipers as per the H2, while suspension is
fully-adjustable, front and rear. It would have been nice to have semi-active
suspension on a machine of this calibre, perhaps in a future model.
New to the H2 SX is of course the panniers, which
are sold as an optional accessory. Designed to complement the lines of the
bike, the mounting points for the panniers blend visually into the bodywork,
ensuring that the H2 SX still looks good with the panniers off.
While looking visually pleasing, it should be noted
the panniers do make the H2 SX rather wide in the beam, despite the fairing
having been slimmed down from the H2. We got on the H2 SX for size, and were
very aware that the panniers stuck out a fair way on either side.
Unique to the SE model are several items, amongst
which is launch control, a first for a Kawasaki sports-tourer. Also standard
equipment on the SE are LED cornering lights, a three-element unit mounted on
the left and right sides of the fairing that are activated when the bike is
leaned into a corner, with the number of lit elements determined by the lean
angle.
Inside the cockpit the H2 SX comes with an LCD screen,
while the SE version comes with a full-colour TFT-LCD unit that has two user
selectable modes – Touring or Sport – that displays different parameters for
the type of riding being done. Also fitted to the H2 SX SE is launch control
and a quickshifter.
Other differences between the SX and SX SE are steel
braided brake lines on the SE, a 12-volt DC socket, larger windscreen, centre
stand, heated grips and wheels and rear-hub with machined accents. Both SX
models come with Kawasaki’s standard suite of riding aids, including traction
control, cornering ABS, cornering management, electronic cruise control and
engine braking control.
It should be noted that some of the equipment fitted
to the SE version of the H2 SX cannot be retro-fitted to the base model, thus
the buyer of the SX has to make a decision at the point of purchase as to which
variant he or she wants. There are only two colour options available – Metallic
Carbon Gray/Metallic Matte Carbon Gray for the 2018 Kawasaki H2 SX, and Emerald
Blazed Green/Metallic Diablo Black for the H2 SX SE.
