This past July, Polaris took the covers off its revamped RZR lineup, including the new 2015 RZR 900 and RZR S 900. Polaris redefined the first two RZR products ever built by providing the vehicles with a huge bump in power and improved suspension performance. Polaris just added to the RZR 900 family with the release of the new 2015 RZR 4 900 EPS.

The RZR 4 900 EPS shares many of the same attributes as the RZR S 900; 75 horsepower, ProStar 900 EFI engine, dual A-arm front and rear suspension, high-performance all wheel drive (AWD), 60 in. width, and accessory integration. A 106.5 in. wheelbase accommodates two more passengers.

At the heart of the RZR 4 900 EPS is a 75 horsepower ProStar 900 engine, which offers 40% more power than the RZR 4 800 model it replaces. To get more of that power to the ground, the vehicle features the RZR XP transmission, which is specifically geared to optimize the power of the engine for a what Polaris calls a “huge improvement in acceleration over the RZR 4 800.” As well, Polaris says the new, high-flow clutch intake system provides more airflow and decreases belt temperature to improve the durability of the clutch system.

As for suspension, the RZR 4 900 EPS features 12.25 in. of front suspension travel and 13.2 in. in the rear to go along with FOX Performance Series 2.0 Podium X Shocks. According to Polaris, the suspension can be tuned for exactly the way you ride. The unit’s tubular chassis is paired with a completely new suspension geometry, which is designed to result in less vibration inside the vehicle and more responsive suspension feedback. Connecting the RZR 4 900 EPS to the ground are new 27 in. GBC Dirt Commander tires. Polaris says these tires offer better side bite, stiffer sidewalls, better tracking through corners and increased durability.

To help improve agility, Polaris added 1.3 in. of rear track width while maintaining the overall vehicle width of 60 in. While all RZR vehicles are equipped with On-Demand True AWD, the RZR 4 900 EPS utilizes Polaris’ High-Performance AWD, which is designed to keep the front wheels pulling stronger and longer, maximizing power delivery to the ground in every condition for a more responsive ride. Polaris boasts this system provides increased traction without sacrificing steering.

Another new feature is 20% faster steering response with an improved two-turn lock to lock steering ratio. Coupled with the electronic power steering with variable assist, the steering system is designed to help the operator feel less fatigued.

Both driver and passenger seats are equipped with seat sliders for easy adjustability, and all four seats offer improved bolstering and more hip cushioning. A thin-film technology under the cover of the seats offers a drier ride in wet conditions. Rear passengers benefit from more foot and leg room, and an angled floor. The vehicle also features four, factory-installed quarter doors to make getting in and out easier.

First found on the RZR XP 1000, the cockpit of the RZR 4 900 EPS features front LED floor lighting and a blue back-lighted instrument cluster, readable both in direct sunlight and at night. A large center storage area, bigger glove box and deeper rear box provide more storage space.

The RZR 4 900 EPS is easier to service due to the ease of access of the major components. The air filter, spark plugs and oil fill are located under the removable box panel in the cargo box of the vehicle while a panel between the seats houses the dipstick and oil filter, and is accessible without removing the seats. The vehicle features an integrated transmission with only one check/fill point and grease zerks for both the inboard and outboard bushings of the A-arms. To improve durability, Polaris added new stronger ball joints, half shafts and hubs with improved bearing fit. To allow for easy electrical accessory installation, the RZR 4 900 EPS features a terminal block for wiring under the hood and a bigger battery with 44 amp-hours of capacity and 575 cold-cranking amps.
