Phoenix, AZ - Polaris has consistently
pushed the envelope in performance with their
Ranger RZR line of SXS vehicles. In 2008, Polaris
announced the original RZR 800, which was the
first high performance trail capable side by side
with a width of only 50 inches. The following
year, Polaris released the RZR S with its wider
width targeted for wide open spaces. Once again,
in 2010, Polaris surprised everyone with the creation
of a new market segment with the release of the
RZR 4, which was the first ever four passenger
performance side by side. Now for the fourth straight
year, Polaris has expanded their Ranger RZR lineup
with the all-new high performance 2011 Polaris
RZR XP 900.
The new Polaris RZR XP 900 was announced to
the public on 1/1/11, and Polaris has been quick
to point out that the RZR XP is not just a reworked
RZR of past years. The XP has an all new Pro
Star 900 engine that produces 88 HP at the crank
and is coupled to a new purpose built highly
efficient transmission/rear gear case combination.

46mm Mikuni throttle bodies power the
875cc Pro Star Engine |
This new engine combination is mounted in a
front to rear configuration instead of side
to side as with previous RZR models. The Pro
Star 900 engine is fed by dual 46mm Mikuni throttle
bodies that are mounted extremely close to the
engine for the best possible throttle response.
This engine and transmission arrangement transfers
65 percent more power to the ground than RZR
800. The XP 900 accelerates 29 percent quicker
than the nearest competitor thanks to its superior
HP to weight ratio.
As the performance of an engine increases so
do the demands on the cooling system. Polaris
has redesigned the front grill to maximize inlet
air to the all new larger radiator. Front air
dams have been placed on both sides of the front
facial these dams direct air out and around
the chassis creating a low pressure zone behind
the radiator and helping to keep hot air from
building up behind the fenders.
