The Polaris
RZR XP 900 engine is an all-new engine
designed specifically for the XP 900 &
it is not a Weber engine. The 875cc engine
produces an impressive 88HP with dual
46mm throttle bodies compared to the RZR
S, which just has one 39mm throttle body.
Also, the engine is installed inline with
the rear end direct drive rear axles unlike
the original RZR, which reduces power
loss to the wheels for improved performance

because it is one of the Yokley Racing
Units)
