traction. Polaris beefed up the drivetrain
for the extra 13 horsepower over the
Jagged X XP 900 LE, but the CVT belt
proves to be a weak link in the dunes.
Deep sand creates such a drag on the
CVT (with the XP 1000 producing more
fighting force) that heat buildup cooks
the CVT belt and it fails. Camp RZR
saw multiple blown XP 4 1000 CVT
belts, so you can be sure Polaris is on
top of it.
HOW AGILE IS THE HANDLING?
Not so agile. Not only is the wheelbase 117 inches and the weight 1596
pounds, the extra travel of the XP 4
1000 creates a lot of body roll, much
more than the XP 4 900. The Maverick
Max 1000 has a 113.8-inch wheelbase
and 14 inches of travel for less body
roll, while the Wildcat 4 is longer at 124
inches and has more travel. We expect
the XP 4 1000 will fall in between the
Can-Am Max and Wildcat 4 in turn-
ing prowess, although the XP 4 1000
doesn’t have stadium seating like the
Max and Cat, so it has a lower center
of gravity when fully loaded. The XP
4 1000 does carve well in the dunes,
and the on-demand AWD system helps
it dive into turns without pushing on
HOW ABOUT THE HIGH-END
It’s well-tuned for general trail rid-
ing. Conventional A-arms and Walker
Evans Racing 2.0 piggyback shocks
with anti-bottoming needles provide 16
inches of front travel, and longer trailing
arms provide 18 inches of rear travel
with remote-reservoir WER 2. 5 needle
shocks. Ours came with the compres-
sion adjuster at 10 clicks out on the
front shocks and 12 out on the rear.
We bottomed the front several times
on steep slip faces in the dunes, so we
went in three clicks. On harder surfac-
es, we backed off of rear compression
to 10 out.
HOW STRONG ARE THE BRAKES?
Terminator strong! When you’re
doing 70 mph, you need great brakes,
and the XP 4 1000 has twin-piston
hydraulic calipers squeezing 248mm
rotors on all four corners. The Maverick
Max has 220mm front and 214mm rear
rotors, and only the front calipers have
twin pucks, while the Wildcat 4 has
smaller non-perforated rotors.
WHAT ABOUT TRAIL COMFORT?
It’s great! The seats are comfortable
and the fronts are adjustable. The doors
are works of art that provide protection
The speedometer is easy to read, and the
engine-coolant temperature display is handy.
The center storage bin holds an iPhone or
GPS in a padded compartment, plus spare
gloves and goggles.
Front seats are adjustable (sand can foul the mechanism) and removable, and the nice secure
doors curve outward for more cabin room.
Two 93mm pistons ride on 73.5mm stroke for a true 999cc, the largest in class. Claimed output is 107 horsepower. Polaris upgraded the
whole drivetrain for the extra stress, but be sure to break in the belt
before hot-rodding the XP 4 1000.
Air enters from the grill on the right side of the bed into a large, still
airbox with an RZR 800-type filter, and then clean air travels to the
large plenum chamber and two 48mm EFI throttle bodies.
