You’ve probably asked yourself: Is the extra power of the 570 worth the extra cash? Can the 450 really handle the tough stuff? It’s a choice that impacts your wallet, your weekend fun, and your workload around the property.
We promise to cut through the marketing hype and give you the real-world, in-the-dirt breakdown you need. This comprehensive polaris 450 ho vs 570 guide will walk you through the critical differences in engine performance, handling, long-term ownership costs, and exactly who each machine is built for. By the end, you’ll know with confidence which Sportsman belongs in your garage.
At the Heart of the Matter: Engine & Performance Showdown
The biggest difference between these two quads is right there in the name: the engine. While they share the same chassis, the powerplant dictates the entire character of the machine. Let’s pop the plastic and see what’s what.
The Proven Workhorse: Polaris Sportsman 450 H.O. Engine
The Sportsman 450 H.O. is powered by a 500cc single-cylinder ProStar engine. Don’t let the “450” name fool you; it’s a capable motor that Polaris tunes to produce a very respectable 33 horsepower.
This engine is all about smooth, predictable, and reliable power. It’s not going to rip your arms off, which makes it fantastic for new riders or for long days doing chores where you need control, not outright speed. The power delivery is linear and easy to manage on tight, technical trails.
The Power Upgrade: Polaris Sportsman 570 ProStar Engine
Step up to the Sportsman 570, and you get the legendary 567cc single-cylinder ProStar engine, a true icon in the ATV world. This liquid-cooled beast churns out an impressive 44 horsepower. That’s a 33% jump in power over the 450.
You feel that extra 11 horsepower everywhere. It accelerates harder, climbs hills with less effort, and has more grunt for spinning bigger, more aggressive mud tires. If you ride with a passenger (on 2-Up models), tackle steep terrain, or just love the feeling of strong acceleration, the 570 delivers.
Real-World Feel: What the Power Difference Means on the Trail
On a flat, easy trail, you might not notice a huge difference. But the moment the terrain gets challenging, the engines show their true colors.
- Climbing Hills: The 570 will chug up steep, loose inclines with more authority, often without needing a running start. The 450 will make it up most of the same hills, but it will be working harder.
- Hauling & Towing: While their tow ratings are often identical, the 570’s engine will be less strained when pulling a heavy trailer full of firewood or dragging a food plot implement.
- Mudding: The 570 has the extra grunt needed to turn and clear mud from aggressive tires, making it the superior choice for deep bogging.
- Rider Fatigue: Interestingly, the smoother 450 can sometimes lead to less rider fatigue on long, slow-going days. The snappy throttle of the 570 is fun but requires a bit more finesse.
Polaris 450 HO vs 570: Suspension, Handling, and Ride Quality
Power is nothing without control. Fortunately, both the 450 and 570 are built on the same excellent Sportsman platform, known for its comfortable ride. However, there are subtle differences, especially as you move up in trim levels.
Shared DNA: The Sportsman Chassis and Suspension Basics
Both models feature a MacPherson strut front suspension and a dual A-arm Independent Rear Suspension (IRS). This setup is famous for soaking up rocks and ruts, providing a plush ride that keeps you comfortable all day long.
This shared foundation is one of the key benefits of polaris 450 ho vs 570 models; you get a premium ride quality no matter which engine you choose. The basic geometry is identical, so the core handling characteristics are very similar.
Does the 570 Handle Better? Ground Clearance and Tire Differences
This is where trim levels matter most. Base models of both the 450 and 570 often come with the same steel wheels and basic 25-inch tires. They offer similar ground clearance, typically around 11.5 inches.
However, when you step up to a 570 Trail, Premium, or other special edition package, you often get upgraded, more aggressive tires and cast aluminum wheels. Better tires are the single biggest handling upgrade you can make, providing more grip, better puncture resistance, and a more confident feel in corners.
Steering and Control: The EPS (Electronic Power Steering) Factor
Both the 450 and 570 are available with and without Electronic Power Steering (EPS). Our advice? Get the EPS.
EPS drastically reduces steering effort, especially in 4WD when navigating rock gardens or tight trees. It also dampens kickback through the handlebars, saving your wrists and shoulders. If you plan on long trail days or using your ATV for snowplowing, EPS goes from a “nice-to-have” to a “must-have.”
Utility and Features: What Do You Get for Your Money?
An ATV is a tool as much as it is a toy. Both these machines are built to work, but the features can vary significantly based on the trim package you select.
Racking and Towing Capacity
Here, the two machines are nearly identical. Both typically boast a front rack capacity of 90 lbs and a rear rack capacity of 180 lbs. The standard 1.25″ receiver hitch on both is usually rated for an impressive 1,350 lbs of towing.
For most farm chores, hunting tasks, or yard work, either machine has the backbone to get the job done. The key difference, as mentioned earlier, is how hard the engine has to work to handle those loads.
Trim Level Breakdown
This is where the choice gets complex. Polaris offers a wide array of trims:
- Base Model: Your no-frills workhorse. Steel wheels, no EPS, basic headlights.
- EPS Models: Adds the crucial power steering feature.
- Premium/Trail Models: Often include upgraded wheels and tires, premium paint, LED lights, and sometimes front bumpers or winches.
Often, a fully-loaded 450 H.O. Premium can cost as much as a base model 570. This is a critical decision point: do you want a more powerful engine or more features like EPS, better tires, and lights?
A Polaris 450 HO vs 570 Care Guide for Long-Term Ownership
Owning an ATV means maintaining it. A solid understanding of this is one of the most important polaris 450 ho vs 570 tips we can offer. Fortunately, both machines are very DIY-friendly and share many of the same service points.
Common Problems with Polaris 450 HO vs 570 Models
No machine is perfect. Based on what we see in the shop, here are a few things to watch for:
- Bushings: The A-arm bushings are a common wear item. You’ll know they’re going bad when you feel slop in the suspension or hear clunking. Upgrading to aftermarket bushings from brands like SuperATV or All Balls Racing is a great long-term fix.
- CV Boots: A torn CV boot is the fastest way to ruin a CV axle. Always inspect them for tears after a ride, especially if you’ve been in sharp rocks or sticks.
- Battery Terminals: Polaris battery terminals can sometimes work loose. A quick check with a wrench every few months can prevent a no-start situation on the trail.
Maintenance Schedules and DIY-Friendly Tasks
Your owner’s manual is your best friend. Both the 450 and 570 require regular oil changes, air filter cleanings, and chassis lubrication. These are simple jobs you can do with basic hand tools.
- Engine Oil: Use the correct Polaris PS-4 oil. It’s formulated for these specific engines. Changing it is as easy as on a lawnmower.
- Air Filter: Pop the seat, open the airbox, and check your filter. In dusty conditions, check it after every ride. A clean filter is cheap horsepower.
- Grease Zerks: Get a good grease gun and hit all the suspension zerk fittings regularly to keep things moving smoothly.

- Fuel Efficiency: The 450 H.O. is slightly more fuel-efficient than the 570. Regardless of model, a smooth throttle hand and a clean air filter will maximize your miles per gallon.

Making the Case: Who Should Upgrade to the 570?
The Sportsman 570 is the best-selling automatic 4×4 ATV for a reason. You should spend the extra money on the 570 if:
- You Crave Power: If you’re an experienced rider who loves strong acceleration and a “giggle factor,” the 570 is the clear winner.
- You Ride at High Elevation: The extra power helps compensate for the power loss that occurs in thin mountain air.
- You Ride in Thick Mud or Snow: The 570 has the necessary grunt to spin the tires and keep you moving in heavy, power-robbing conditions.
- You Plan on Adding a Plow or Larger Tires: These accessories demand more power, and the 570’s engine handles the extra strain with ease.
