The Polaris 900 Side by Side: Why It’s a Trail Legend
Before we dive into the nuts and bolts, let’s appreciate what makes the polaris 900 side by side platform so special. Whether you’re in a sporty RZR 900, a workhorse Ranger 900, or a versatile General, the heart of your machine is likely the ProStar 900 engine.
This 875cc, twin-cylinder engine is renowned for its snappy throttle response and reliable power delivery. It’s a power plant that’s proven itself over years of hard use, from dusty deserts to muddy forests. This reliability is one of the key benefits of polaris 900 side by side ownership.
These machines offer a fantastic balance. They have enough power to be thrilling but are nimble enough to navigate tight, technical trails where bigger 1000cc+ machines might struggle. This versatility makes them a top choice for a huge range of riders.
Your Essential Polaris 900 Side by Side Care Guide
Proper maintenance is the single most important factor in your machine’s longevity and reliability. Following these polaris 900 side by side best practices will save you headaches and money down the road. Think of it as an investment in future fun.
Pre-Ride Inspection: The 5-Minute Lifesaver
Never, ever skip your pre-ride check. This simple routine can catch a small issue before it becomes a major, trip-ending failure. We call it the T-CLOCS method, adapted for UTVs.
- T – Tires & Wheels: Check tire pressure. Look for any cuts, punctures, or damage. Grab each wheel and check for any play or looseness in the wheel bearings.
- C – Controls & Cables: Test your throttle and brake pedals for smooth operation. Check your steering for any binding or excessive play.
- L – Lights & Electrics: Turn the key on. Test your headlights (high and low beams), brake lights, and any accessory lights.
- O – Oil & Fluids: This is critical. Check your engine oil level. Take a quick look at the coolant overflow bottle and the brake fluid reservoir. Spot any drips or leaks underneath the machine.
- C – Chassis & Suspension: Visually inspect your A-arms, trailing arms, and radius rods for any cracks or bends. Look at your shocks for any signs of leaking oil.
- S – Spares & Supplies: Make sure your toolkit, tire plug kit, and spare belt are secured and ready to go.
Engine Oil & Filter: The Heartbeat of Your Machine
Clean oil is cheap insurance. The ProStar engine works hard, and its oil does, too. Don’t cheap out here. Use a quality full-synthetic oil designed for powersports engines, like Polaris PS-4 Full Synthetic Oil.
Change your oil and filter according to the schedule in your owner’s manual—or more frequently if you ride in extremely dusty, wet, or high-load conditions. A good rule of thumb for the average trail rider is every 50 hours or 6 months.
Air Filter Maintenance: Breathe Clean, Run Strong
Your air filter is the only thing protecting your engine’s internals from dust and dirt. A clogged filter robs power and efficiency, while a damaged one can lead to catastrophic engine failure. This is one of the most crucial polaris 900 side by side tips we can offer.
After every dusty ride, pull the filter out and inspect it. Tap out the loose dirt. Use compressed air from the inside out to blow out finer particles. Never use high pressure, as it can tear the filter media. Replace it when it’s visibly stained, damaged, or after a few cleanings.
Diagnosing Common Problems with Polaris 900 Side by Side
Even with perfect maintenance, things can sometimes go wrong on the trail. Knowing how to diagnose the basics can be the difference between a quick fix and a long walk home. Here are some of the most common problems with polaris 900 side by side models and how to approach them.
Starting Issues: Clicks, Cranks, and No-Starts
You turn the key and… nothing. Or maybe just a click. First, ensure your machine is in Park or Neutral. Next, check your battery connections. A loose or corroded terminal is a very common culprit. Use a 10mm wrench to tighten them.
If the battery is good and you hear a click from the solenoid but the engine doesn’t turn over, you might have a bad starter or solenoid. If it cranks but won’t fire up, your issue is likely related to fuel or spark. Check your fuses first, especially the fuel pump fuse.
Overheating Woes: Keeping Your Cool on the Trail
If your temperature light comes on, stop immediately in a safe place and shut the engine off. Let it cool down. The most common cause is a radiator packed with mud or debris. Never spray a hot radiator with cold water, as it can cause damage.
Once cool, check your coolant level in the overflow bottle. If it’s low, you may have a leak. Also, check that your radiator fan is kicking on. If the fan isn’t running when the engine gets hot, you could have a bad fan motor, relay, or sensor.
Belt Problems: Squeals, Slips, and Smells
The CVT drive belt is a wear item. A glazed, worn, or burnt belt will cause poor performance, slipping, and eventually break. You’ll often smell a distinct burning rubber odor right before it fails.
Always carry a spare belt and the simple tools needed to change it. Learning this process in your garage is far better than figuring it out on a dark trail. Proper break-in of a new belt is also critical for its lifespan. Follow the manufacturer’s procedure precisely.
Smart Upgrades: How to Polaris 900 Side by Side for Peak Performance
Modifying your machine is half the fun of ownership. The key is to spend your money on upgrades that actually improve your experience. Here’s how to polaris 900 side by side for better capability and durability.
Tires & Wheels: The Foundation of Your Ride
The single best upgrade you can make is a good set of tires. The stock tires are often a compromise. Choosing a tire that matches your typical terrain—whether it’s rocks, mud, or hardpack—will transform your machine’s handling and traction.
Consider an 8-ply or higher rated tire for better puncture resistance. Paired with a set of quality aftermarket wheels, you can improve stability with a slightly wider offset and add some personal style.
Suspension Upgrades: Smoothing Out the Bumps
If you find yourself bottoming out frequently or feel the ride is too harsh, it might be time for a suspension upgrade. You don’t have to break the bank on full race-spec shocks.
A simple and effective upgrade is a set of heavy-duty tender springs for your stock shocks. This can dramatically improve the ride quality and give you back some lost ride height. For more serious riders, a full shock replacement from brands like Walker Evans or FOX is a game-changer.
Lighting and Accessories: See and Be Seen
Good lighting is a safety essential, especially if you ride at dusk or at night. An LED light bar is a popular and effective addition. Also, consider adding a whip light or chase lights to improve your visibility to other riders in dusty conditions.
Other must-have accessories include a winch, which is invaluable for recovery, and a set of full skid plates to protect the underside of your UTV from rocks and stumps.
Riding with Responsibility: Sustainable Polaris 900 Side by Side Practices
Being a good steward of the trails is everyone’s responsibility. Adopting a few sustainable polaris 900 side by side habits ensures our riding areas stay open and beautiful for years to come.
Follow the principles of Tread Lightly! Stay on designated trails, never blaze your own path. Cross streams only at designated crossings to protect fragile ecosystems. An eco-friendly polaris 900 side by side is one that’s well-maintained to prevent fluid leaks on the trail.
Pack out everything you pack in. Leaving trash behind ruins the experience for everyone. By being a responsible rider, you become an ambassador for the entire off-road community.
Frequently Asked Questions About the Polaris 900 Side by Side
How often should I change the oil in my Polaris 900?
The manufacturer’s recommendation is a good starting point, typically around 100 hours. However, for most riders, we at FatBoysOffroad recommend changing the engine oil and filter every 50 hours or every six months, whichever comes first, especially if you ride in harsh conditions.
What’s the most common failure point on a Polaris 900?
Aside from wear items like belts and brake pads, one of the more common issues can be wheel bearings, especially if you ride in a lot of mud and water. Other areas to watch are suspension bushings and ball joints, which wear over time and can cause sloppy steering and handling.
Can I make my Polaris 900 street legal?
This depends entirely on your state and local laws. Many states have provisions for making a UTV street legal, but it typically requires adding specific equipment like a horn, turn signals, mirrors, a lighted license plate bracket, and a windshield. Always check with your local DMV for specific requirements.
What are the benefits of a clutch kit for my Polaris 900?
A clutch kit is one of the best performance mods you can make. It doesn’t add horsepower, but it changes how your machine delivers power to the ground. A good kit can improve acceleration, provide better back-shifting when climbing hills, and help compensate for power loss from adding larger tires, all while improving belt life.
Your Polaris 900 is more than just a machine; it’s a ticket to adventure. By understanding its needs and learning how to care for it, you’re not just a rider—you’re a true enthusiast. Take your time, use the right tools, and never be afraid to ask for help.
