Kawasaki Teryx4 EPS 4x4 UTV liquid-cooled
V-Twin engine |
Like the frame, the Teryx4’s 749cc V-twin
four-stroke engine is also new, offering approximately
15 percent more power than the already stout unit
in the two-seat Teryx, along with all the durability
to deal with the rigors of spirited fun in challenging
off-road environments. The V-twin design is revered
for its stump-pulling power and easy-to-harness
flexibility, which makes it the perfect powerplant
for a machine like the Teryx4, which thrives on
instantaneous and controllable low- and mid-range
response partnered with eye-opening hauling ability.
In fact, engineers purposely gave the big Vee
a bit of a dual personality: there’s exciting,
arm-straightening yank when driven solo or with
a single passenger, but plenty of torque and grunt
for carrying more people or heavier loads –
much of it due to revised camshaft profiles and
equal-length exhaust headers.
Liquid cooling – assisted by a large-volume
radiator and large-diameter fan – keeps
temperatures down and reliability up with help
from an array of superb engineering: optimized
piston-wall thickness; special surface treatments
to piston pins, small and big end bearing surfaces;
idealized crank journal bearing sizes; robust
transmission design; and much more.
Electronic fuel injection – featuring
new fine-atomizing 12-hole injectors –
offers easy starts and perfect throttle response
at sea level and at the higher elevations you’ll
want to discover again and again. The FI system
offers automatic mixture compensation, automatic
idle adjustment and easy, choke-free starting
via a sophisticated array of sensors for inlet
air pressure, throttle position, crankshaft
position, rpm and coolant temperature.

| To
put the V-twin engine power to the ground
Kawasaki used a CVT transmission with
a centrifugal clutch assembly |
Routing all that impressive and usable power
to the LE’s lightweight aluminum wheels
is the latest in modern drivetrain technology:
a continuously variable transmission (CVT),
a category-first centrifugal clutch assembly
and an electrically selectable 4WD system featuring
instant-switch access to 2WD, 4WD and 4WD+Front
Differential Lock system. The CVT is well known
for its quick response and direct engine “feel”
in sportier riding situations, where engine
power is used to control the chassis while turning
and in rough conditions. The key to the Teryx4’s
dual-mode personality is its category-first
centrifugal clutch, which offers an extra degree
of precision slow-speed power manipulation and
smoothness, which is ideal for tricky terrain
(rock crawls, etc.) or slow-speed work where
precise throttle manipulation is key. The oil-bathed
clutch design also contributes to improved CVT
belt life by lessening shock and belt deflection.
