The first Polaris XP 900 was impressive. Gobs of power and suspension travel made the two-seat UTV the best we'd tested. When Polaris introduced the XP 900 4, we didn't give it much thought. The larger RZR would have a harder time on tight trails. Wrong. For us, the four-seat RZR XP 900 4 LE works better, especially at higher speeds and steep climbs.
The RZR XP 900 4 LE features seating for four and its Electronic Power Steering (EPS) makes steering easy in all conditions. The big UTV doesn't need to be manhandled through the rocks, nor does the steering wheel jerk out of your hands when hitting off-camber after a jump. The EPS is one of the ingredients that makes the XP 900 4 fun to drive.
Another ingredient is the fuel-injected 875cc DOHC twin-cylinder four-stroke ProStar 900 mill. With 88 horsepower, it has no problem powering the XP 900 4 LE to the governed 75 mph top speed. Our earlier XP 900 hit the governor at 80. Why is the more stable four-seater limited to 75? As few will see these speeds in actual use, maybe that question is irrelevant. Anyway, the powerful, reliable engine coupled with the PVT (Polaris Variable Transmission) allows the XP 900 4 LE to work at any speed, in the rocks or wide-open sand. As the rear has a spool and the front features a Polaris automatic locking differential, the RZR powers on, even with three wheels in the air.
The double A-arm front and trailing-arm rear suspension with Walker Evans coilovers provides 13.5 inches and 14 inches of travel, respectively. The four-seat UTV has no problem traveling over big whoops with ease—much more ease than the two-seater. Even when we get rambunctious with the throttle and hit giant whoops a bit too fast, the XP 900 4 LE's rear doesn't unweight and try to swap ends as some UTVs want to do.
The Polaris RZR XP 900 4 LE is more of everything. It has more steering response, more stability at higher speeds or on steep climbs, more seating room, and—for what we do in the dirt—is more fun!
