WHAT’S NEW FOR 2015?
The 2014 XP 1000 was a complete
and total success. Polaris took a class-/
industry-leading machine, the XP 900,
and gave it a stronger chassis, longer
wheelbase, more suspension travel and
a huge power boost. Well-thought-out
accessory integration was another huge
improvement over any previous UTV,
from Polaris or otherwise. The key-powered accessory buss bar alone has
saved us hours upon hours of garage
time over the past year. Instead of
reinventing the nearly perfect “wheel,”
Polaris refined the original.
The XP 1000 had very few
weaknesses its first year. The breakage-prone CV axles and ball joints from the
900 were upgraded with beefier parts,
and they proved a whole lot more
durable. The skimpy, ATV-sized, 10mm
wheel studs were upgraded to a much
more UTV-appropriate 12mm size.
The one area that didn’t really see any
improvement was the clutch belt. The
2014 XP 1000 used the exact same belt
and clutch components as the lighter-weight, lower-horsepower XP 900, the
only difference being clutch tuning with
weights, springs, etc. Many XP 1000
owners experienced belt failures, and
while it is considered a consumable
part, nobody enjoys lying under a hot
machine changing a clutch belt in the
desert or dunes.
It has been determined that the
number-one enemy of clutch-belt life
is excessive heat. Many racers and
aftermarket builders were successfully
adding electric blower systems and
ductwork to keep the XP 1000 clutches
cool. Polaris wasn’t happy about its
flagship machine needing help from the
aftermarket to keep its core customers
happy, so Polaris engineers designed a
new CVT cover with ducting that draws in
additional air to cool the clutch system. This
new cover and ducting comes stock on the
2015 model in conjunction with a new and
improved clutch belt and secondary helix.
This new clutch cover drastically reduces
clutch temperatures and is an easy upgrade
for the 2014 model.
The other area of improvement is power.
While the XP1K was already clearly the
fastest production UTV around, who doesn’t
want more power and torque? Polaris
bumped up the compression ratio, tweaked
the cams, and installed bigger valve springs
to create an additional 3 horsepower
over the 107-horsepower 2014 model. In
order to keep up with changing emissions
regulations, the EFI system has been
Polaris made a great machine even better for 2015, as
the RZR XP 1000 gets more horsepower, a cooler-running
CVT belt, re-tuned suspension, and a bunch of little tweaks
for 2015. It works so well on the trail that it’s easy to
overcook a turn and get up on the mongo bicycle.
A new O2 sensor and catalytic converter on the two-into-one exhaust
help fuel metering to extend fuel range and lower emissions, which
keeps the EPA happy. Three more horsepower come from the same
upgrades the ’ 13 Jagged X XP 900 got: higher compression pistons,
new cam timing and new valve springs.
A new outer CVT cover incorporates a third air duct for cooling airflow,
and Polaris claims the belts run 30 degrees cooler. If you do have to
change a CVT belt on the trail, the new cover complicates removal, as you
have to undo the duct-mount bolt and the hose clamp. Check out the cool
brake-line routing on the trailing arm and roost shield for the shock shaft.
