Both of these machines offer a fantastic gateway into the world of off-roading, but they deliver very different experiences.
You’ve probably heard the 800 has more power, but the 570 is newer and more nimble. How do you cut through the noise and figure out which one is the right fit for your garage, your budget, and your kind of trail riding?
We promise this definitive guide will break it all down for you. We’ll dive deep into engine performance, real-world handling, common problems you need to watch for, and the true cost of ownership. By the end, you’ll know exactly which RZR is calling your name.
Engine Deep Dive: ProStar 570 vs. Liberty 800
The heart of any machine is its engine, and this is where the 570 and 800 are fundamentally different. It’s not just about displacement; it’s about design philosophy, power delivery, and efficiency. This is a core part of our polaris rzr 570 vs 800 guide.
The Modern ProStar 570: Efficiency and Pep
The RZR 570 is powered by the ProStar engine, a more modern, single-cylinder, dual-overhead-cam (DOHC) design. It puts out around 45 horsepower, which might not sound like a lot, but how it delivers that power is key.
This engine is incredibly responsive and peppy at lower speeds. It’s designed for efficiency, both in fuel consumption and in how it transfers power to the wheels. Think of it as a high-revving, energetic motor that loves to be in the meat of its powerband on tight, twisty trails.
One of the biggest benefits of polaris rzr 570 vs 800 when considering the 570 is its fuel economy. You’ll spend more time on the trail and less time worrying about your next fuel stop, a major plus for long-haul adventures.
The Classic Liberty 800: Torque and Power
The RZR 800 uses the older, twin-cylinder Liberty engine. This is a pushrod engine, a simpler and more traditional design that produces around 55 horsepower. The real story here isn’t just the horsepower bump; it’s the torque.
The twin-cylinder layout provides more low-end grunt. This is noticeable when climbing steep hills, plowing through thick mud, or when you just want that satisfying feeling of acceleration on an open fire road. The power delivery is smoother and feels more substantial than the 570.
However, this power comes at the cost of efficiency. The Liberty 800 is thirstier, and its design places the engine further back, which can affect heat management in the cab—something we’ll touch on later.
Chassis and Handling: How They Feel on the Trail
Power is useless if you can’t put it to the ground. The chassis and suspension setup determine how a UTV feels, how it handles obstacles, and ultimately, how confident you feel behind the wheel. Both the 570 and 800 were built on a similar platform, but key differences make them feel like totally different animals.
Trail Agility: The 50-Inch Advantage
Most base model RZR 570s and 800s came in a 50-inch width. This is their superpower. This narrow stance allows them to legally access width-restricted trails that are off-limits to wider machines. If your local riding area is full of tight, tree-lined paths, this is a massive advantage for both models.
Where the 570 shines is its drivetrain layout. The ProStar engine is mounted longitudinally (front to back), which allows for a narrower powertrain. This results in more room for the rear suspension to travel and better weight distribution, giving it a more planted and predictable feel in corners.
The 800’s engine is mounted transversely (side to side), which can make it feel a bit more top-heavy in comparison. It’s still a capable machine, but the 570 often feels more nimble and confidence-inspiring for less experienced riders on technical terrain.
Suspension and Ride Comfort
Both machines typically feature a dual A-arm suspension front and rear. Early models offered around 9 inches of travel in the front and 9.5 inches in the rear. It’s a decent setup for general trail riding, capable of soaking up rocks, roots, and ruts at a reasonable pace.
Neither machine is going to ride like a modern, long-travel RZR XP 1000. The ride can be choppy in rough sections. Upgrading the stock shocks to something like a set of Walker Evans or Fox shocks is one of the most popular and effective mods for both the 570 and 800 to improve ride quality significantly.
The Ultimate Polaris RZR 570 vs 800 Reliability Showdown
When you’re buying a used machine, reliability is everything. You want to spend your weekends riding, not wrenching. Understanding the common problems with polaris rzr 570 vs 800 can save you a ton of headaches and money down the road.
Common Problems with the RZR 570
The ProStar 570 engine is generally considered reliable, but it’s not without its quirks. Here’s what to watch for:
- Noisy Top End: The DOHC design can sometimes develop a “ticking” sound. While often harmless, it’s worth having a good mechanic listen to it before you buy.
- Clutching: The stock clutch setup is decent, but it can wear prematurely if the machine is ridden hard or has larger tires without a clutch kit. Look for signs of a slipping belt (a burning rubber smell).
- Wheel Bearings: Like many UTVs, the 570 can go through wheel bearings. Check for excessive play by grabbing the top and bottom of each tire and trying to wiggle it.
Known Issues for the RZR 800
The Liberty 800 is a workhorse, but its older design has some well-documented weak points that every potential owner should know about.
- “Dusting” the Engine: This is the BIG ONE. The stock air intake system on many 800 models was poorly designed, allowing fine dust to bypass the filter and get sucked directly into the engine. This destroys piston rings and cylinder walls, leading to a costly top-end rebuild. ALWAYS inspect the airbox and intake tube for dust and consider upgrading to an aftermarket filtration system immediately.
- Heat in the Cab: The 800’s engine sits right behind the seats, and it can radiate a significant amount of heat into the cockpit, which can be uncomfortable on hot days.
- Differential Pinion Nuts: The front and rear differential pinion nuts have been known to back off, causing catastrophic failure. It’s a common preventative maintenance item to check and re-torque them with Loctite.
Maintenance and Upkeep: A DIY Mechanic’s Guide
For the FatBoysOffroad crew, ease of maintenance is a huge factor. A good polaris rzr 570 vs 800 care guide starts with knowing what you’re getting into. Both machines are relatively simple for a DIYer to work on.
Working on the 570: Simpler by Design?
The 570’s layout generally offers better access to key service points. The oil filter, drain plug, and spark plug are easy to get to. The longitudinal engine placement also makes tasks like changing the drive belt a bit more straightforward.
Parts are plentiful and often more affordable than those for the 800. The shared ProStar platform means many components are used across different Polaris models, keeping availability high.
The 800’s Service Points: What to Know
The 800 is still very DIY-friendly, but some tasks can be more cumbersome. The transverse engine can make accessing certain bolts and components a bit tighter. For example, getting to the starter can be a real knuckle-buster.
A critical maintenance tip for the 800 is to be religious about cleaning your air filter. We can’t stress this enough. After every single dusty ride, pull it, clean it (or replace it), and inspect the intake boot for any signs of dust intrusion.
Eco-Friendly Polaris RZR 570 vs 800 Best Practices
Being a responsible rider is part of the fun. When considering a sustainable polaris rzr 570 vs 800 approach, think about long-term care. The 570’s better fuel economy makes it the slightly more eco-friendly choice out of the box. For either machine, use a drain pan for all fluid changes and dispose of used oil, coolant, and gear lube at a proper recycling facility. A well-maintained engine that isn’t leaking fluids or burning oil is better for the trails we all love.
Cost of Ownership: Purchase Price, Fuel, and Parts
On the used market, a RZR 800 can often be found for a lower initial purchase price than a comparable-year RZR 570. The 800’s known issues, particularly the engine dusting problem, tend to drive its value down.
However, the purchase price is just the beginning. The 570 will almost always be cheaper to run. You’ll save money on fuel every single ride. Parts are also generally less expensive, and you’re less likely to face a catastrophic engine failure if the machine has been cared for.
A pre-purchase inspection by a qualified mechanic is highly recommended for either model, but it is absolutely essential for an 800. The cost of an inspection could save you from a $2,000+ engine rebuild.
