Specifically built for an extreme performance Side x Side. The Polaris ProStar™ 900 engine features 88 HP, Dual OverHead Cams (DOHC), 4 large valves for high RPM power and 180 degree crank shaft for balanced performance. This delivers fast throttle response, groundbreaking power and revolutionary acceleration. This revolutionary acceleration is made possible by the 88 HP lightweight engine and total vehicle weight combined with big-time power to the ground. The result is loads of torque to all four wheels and unsurpassed off-road acceleration.
Without a doubt, it’s the fastest accelerating 4-seat Side x Side available, and fast acceleration equals big smiles and a fun ride for 4. This revolutionary acceleration is made possible by the powerful 88 HP engine and low total vehicle weight -- creating an incredible power-to-weight ratio -- plus massive power to the ground.
The transmission is specifically designed to optimize power from the Polaris ProStar™900 engine. The innovative, lightweight design features a helical cut final drive with optimized gear geometry to maximize efficiency, even at high torque-loads. That means huge power that is efficiently delivered to the ground with minimal driveline noise.
The 3-Link Trailing Arm IRS creates the smoothest, most precise ride in the industry. It’s a proven, durable design, with no excess parts to add weight. It features two rear control arms and a far forward-connecting trailing arm, resulting in a strong yet lightweight system. The industry-first standard 2.5” body Premium Walker Evans™ rear shocks provide the extra volume needed to dissipate heat and provide an incredible 14” of suspension travel to soak up the bumps and whoops.
The long wheelbase of the 4-seat RZR® 4 900 is designed to accommodate the extra seats. It works to smooth out the bumps and whoops for the absolute best off-road ride for 4. And because it’s paired with the 3-link Trailing Arms IRS, you and your passengers get a fast, flat ride that lets you ride longer and maximize the fun.
The 3-Link Trailing Arm IRS and Premium Walker Evans™ shocks work together to create an astounding 12.5” of ground clearance. Whether you’re riding solo or in a group of 4, you ride with greater confidence, clearing rocks, bumps, ruts and obstacles that other off-road vehicles cannot.
Only RZR features the Polaris-exclusive Optimized Mass Design. The engine and other components are strategically placed to create the absolute lowest center of gravity, for the ultimate in razor-sharp performance.
True AWD gives you the ultimate grip to put that 88 HP to work in the corners, whoops and loose terrain. It’s the easiest to use and fastest responding on-demand system, automatically engaging all four wheels when you need more forward traction and reverting back to 2WD when you don’t. This means less wear and tear, easier steering, and maximizes power when you need it most.
To provide precise cornering, the suspension’s radius rods extend deep into the wheel hubs and feature an uneven link geometry that optimizes camber. This allows the tires to lean into the corner through the suspension travel, and plant more tire surface on the ground for maximum control.
Add versatile, high-performance auxiliary lighting to your RZR® XP 1000 by installing a llight bar. These new lighting options complement your vehicle’s headlights and distribute additional lighting across a broader area for outstanding visibility.
Crank up the volume with the new MTX® Premium Overhead Audio Pod, which installs easily and pumps out up to 100 watts of premium audio.
