We promise this isn’t just another boring list of numbers. This is your complete, no-nonsense breakdown of the 2013 polaris rzr 900 xp specs. We’re going to dive deep into what these specs actually mean for you, the rider.
In this guide, we’ll cover the powerhouse engine, the trail-taming suspension, the common problems you need to watch for, and the essential maintenance best practices that will keep your RZR running like a champ. Let’s get to it.
At the Heart of the Beast: Engine and Drivetrain Specs
The soul of any machine is its engine, and the 900 XP came with a screamer. Understanding these core numbers helps you appreciate the raw power at your command and how to best use it on the trail.
The ProStar 900 Engine
Polaris didn’t mess around here. They equipped this RZR with their purpose-built ProStar 900 engine, and it set a new benchmark for the industry at the time.
- Engine Type: 4-Stroke DOHC (Dual Overhead Cam) Twin Cylinder
- Displacement: 875cc
- Horsepower: 88 HP
- Fuel System: Electronic Fuel Injection (EFI)
- Cooling: Liquid
What does this mean for you? That 88 horsepower was a massive number back in 2013, and it’s still incredibly potent today. The DOHC design allows the engine to breathe efficiently and rev quickly, giving you that thrilling acceleration when you mash the pedal. The EFI ensures crisp throttle response and easy starting, whether it’s a cold morning or you’re at high altitude.
Transmission and Drive System
Getting that power to the ground effectively is just as important as making it. The RZR 900 XP’s drivetrain is simple, effective, and built for the demands of off-roading.
- Transmission: Automatic PVT (Polaris Variable Transmission) with P/R/N/L/H gears
- Drive System: On-Demand True AWD/2WD
The PVT is a belt-driven CVT system. It’s smooth and ensures the engine is always in its powerband. The On-Demand AWD is a classic Polaris feature. It runs in 2WD until the rear wheels slip, then it instantly engages the front wheels to pull you through the tough stuff. This is one of the key benefits of 2013 polaris rzr 900 xp specs; it’s intuitive and provides traction exactly when you need it.
The Ride Is Everything: Suspension, Wheels, and Brakes
Power is useless if you can’t control it. The 900 XP’s chassis and suspension were designed to handle aggressive driving over rough terrain. This is where you’ll find some of the most important numbers for off-road performance.
Trail-Taming Suspension
The suspension is arguably what made the XP model so special. It featured premium components and impressive travel numbers that could soak up massive bumps.
- Front Suspension: Dual A-Arm with Fox Podium X 2.0 Shocks, providing 13.5 inches (34.3 cm) of travel.
- Rear Suspension: Trailing Arm with Fox Podium X 2.0 Shocks, providing an impressive 14 inches (35.6 cm) of travel.
These aren’t just basic shocks. The Fox Podium X 2.0 shocks are high-quality, rebuildable shocks with adjustable preload. A great 2013 polaris rzr 900 xp specs tips is to learn how to adjust your spring preload. Add preload (compress the spring) for carrying heavier loads or to increase ride height; reduce it for a plusher ride over small chatter bumps.
Wheels, Tires, and Brakes
The rolling stock and stopping power are your direct connection to the trail. Knowing these specs is vital for maintenance and potential upgrades.
- Front Tires: 27 x 9-12; ITP 900 XCT
- Rear Tires: 27 x 11-12; ITP 900 XCT
- Wheels: Cast Aluminum
- Brakes: 4-Wheel Hydraulic Disc with Dual-Bore Front Calipers
The 27-inch tires were tall for their day, helping the machine roll over obstacles easily. The hydraulic disc brakes provide strong, confident stopping power, which is crucial when you’re descending steep hills or need to stop in a hurry.
Dimensions and Capacities: Know Your Rig’s Limits
This is the practical part of our 2013 polaris rzr 900 xp specs guide. These numbers dictate what trails you can fit on, how much gear you can carry, and how far you can go on a tank of gas.
- Wheelbase: 81.4 in (206.8 cm)
- Dry Weight: 1,190 lbs (539.8 kg)
- Overall Vehicle Size (LxWxH): 108.4 x 64 x 73 in (275.3 x 162.6 x 185.4 cm)
- Ground Clearance: 13 in (33 cm)
- Fuel Capacity: 7.25 gal (27.4 L)
- Bed Box Capacity: 300 lbs (136.1 kg)
- Payload Capacity: 740 lbs (335.6 kg)
The 64-inch width is a key spec. It makes the 900 XP incredibly stable at speed but also means it’s too wide for 50-inch restricted trails. The 13 inches of ground clearance is excellent, allowing you to clear rocks and ruts that would stop lesser machines. Always respect the payload capacity to avoid over-stressing the chassis and suspension.
Common Problems with 2013 Polaris RZR 900 XP Specs and How to Fix Them
No machine is perfect, and the 2013 RZR 900 XP has a few known quirks. Being aware of these common issues ahead of time can save you a lot of headaches and money down the road.
Clutch and Belt Issues
The PVT clutch system works hard. The drive belt is a wearable item and can fail, especially with aggressive driving or oversized tires. Listen for squealing or slipping. Pro Tip: Always carry a spare belt and the tools to change it on the trail. A clutch kit from a reputable brand like EPI or Dalton is a fantastic upgrade for better belt life and performance.
Engine Intake and Dust
The stock air intake location on these models is right behind the cab, where it can suck in a lot of dust kicked up by the rear tires. Dust is the enemy of an engine. Check your air filter before every single ride. Consider a pre-filter or a snorkel kit if you ride in very dusty conditions. This is a critical step in your maintenance routine.
Voltage Regulator Failures
A known weak point on many Polaris models of this era is the voltage regulator. It can overheat and fail, leaving you with a dead battery. Symptoms include dimming lights, an engine that sputters, or the battery not charging. Many owners relocate it to a spot with better airflow or upgrade to a more robust aftermarket unit.

Pre-Ride Checklist (The “T-CLOCS” Method)
Before every ride, do a quick walk-around. It only takes five minutes.
- T – Tires & Wheels: Check air pressure and look for damage.
- C – Controls & Cables: Check throttle and brake operation.
- L – Lights & Electrics: Test headlights, taillights, and AWD switch.
- O – Oil & Fluids: Check engine oil and coolant levels. Look for any leaks.
- C – Chassis & Suspension: Look for loose bolts, and check your axles and CV boots for tears.
- S – Stands (or Brakes): Make sure your brakes feel firm.
Fluid and Filter Service
Stick to your owner’s manual for service intervals, but a good rule of thumb is to change your engine oil and filter every 25-50 hours of use, depending on how hard you ride. Use the correct Polaris PS-4 oil or a compatible high-quality synthetic. When you do your fluid changes, practice sustainable 2013 polaris rzr 900 xp specs by taking your used oil and coolant to an auto parts store or local recycling center for proper disposal. This is an easy, eco-friendly step every DIYer should take.
