IN THE FRAME
Monster power is not always
essential in an off-road machine,
depending on what your intentions
for the vehicle are. This ATV is in
the recreational/utility category, and
the powerplant is ideal in that arena.
The Sportsman 570 has a smooth
44-horsepower engine that is elec-
KEEP IT SUSPENDED
tronically fuel injected with dual
overhead cams and four valves per
cylinder. The 567cc, four-stroke mill
is liquid-cooled and paired to a con-
tinuously variable transmission that
has high, low, neutral, reverse and
park gears. The wheels are shaft-driv-
en through the 4x4 system operated
via a thumb-selector switch on the
with the ADC mode activated. If you
are carrying a load, you would likely
be grateful for the slowing power, but
with just a rider, it is a lot.
You will enjoy a smooth ride at
quick trail speeds on this machine.
The front suspension on the 570 has
been upgraded from Polaris’ tradi-
tional MacPherson strut design to
dual A-arms like those used on the
sportiest Polaris quads. A-arms allow
for more durability and have a much
greater range of damper unit options
both for production supply and for
aftermarket installation. The front
suspension provides 8. 2 inches of
travel out of preload-adjustable coil-
machine’s thumb-throttle housing.
The 570 SP comes with 4x4, 2x4 and
4x4 with Active Descent Control.
The ATV already comes with an
engine braking system that helps
slow the machine down when you
aren’t utilizing the throttle. We like this
feature, but even the previous years
of the system has shown us that it is
almost too powerful. The rear wheels
tend to slide and lock up on downhills or when you chop the throttle.
However, Polaris went a step ahead
with their ADC mode. This makes
all four wheels slow the quad down
heavily when you are in high or low
gear. You can virtually descend moderate hills without touching the brakes
The rear 2-gallon storage bin sits under the rear cargo rack.
The rack can hold up to 180 pounds.
The rear suspension is an independent dual-A-arm type with
9. 5 inches of wheel travel on each side. This system helps
smooth out the ride.
ProStar engine has
enough get-up-and-go for most riders.
We had no problem
getting some air
time on it.
