Polaris has a new trail-capable, 50" wide side-by-side and I'm impressed!
The RZR XP900 is a hard act to follow. With its superb suspension and surprising power, the XP900 is a lot of fun in the dunes, rocks, or dirt. Because of its width, the 900 can't play in the land of ATV trails, though.
Enter the RZR 570. It's narrow enough to legally fit on ATV trails and shares many attributes with its big brother. Its single cylinder Polaris ProStar 570 engine features 4 valves, dual overhead cams and nearly 650 watts of stator output, 40% more than RZR 800. Born from the ProStar 900 that's in the XP900, it features a wet sump for easy serviceability.
The new, lightweight transmission enhances the power of the 570 engine. Its high-torque capacity means more power to the ground, less driveline noise, and lighter weight. The innovative lightweight design features a helical cut final drive with optimized gear geometry to maximize efficiency. Remember the coasting squeek the RZR 800s exhibited? There's none of that here.
With 9" of travel in the front and 9.5" in the rear, the RZR 570's independent suspension works on the trail. The ZF Sachs coilovers are preload adjustable and work surprisingly well, allowing the lightweight RZR 570 to pound over whoops and speed down the trail. The RZR 570 crawls well, too, and does fine when traveling tough trails at slow speed.
Polaris has continued the XP900's body design in the 570. The air filter and spark plug are easily accessed through a panel in the rear storage compartment. The only glaring omission we can find in the 570 is its lack of glovebox.
Look for more on the RZR 570 in 4 Wheel Drive Magazine. I like it!
