What Makes the Can-Am Outlander 850 XMR a Mud-Slinging Legend?
Before we get our hands dirty, let’s break down what sets this machine apart. The “XMR” designation isn’t just a sticker; it’s a factory-engineered package designed for one thing: extreme mud riding. Understanding these components is key to both riding and maintaining it properly.
The Heart of the Beast: The Rotax 850 V-Twin
At its core is the potent, 78-horsepower Rotax 850 V-twin engine. This powerplant is legendary for its torque-rich delivery, giving you the low-end grunt needed to turn massive mud tires and pull yourself out of the stickiest situations. It’s a reliable engine, but it demands clean oil and a clean air filter to perform its best.
Factory-Built for the Deep: Snorkels, Radiator, and Tires
This is where the XMR truly shines. Can-Am didn’t just slap on some big tires and call it a day. They engineered a complete system.
- Relocated Radiator: The radiator is moved to the front rack, high above the mud and debris. This is a critical feature that prevents it from getting caked in mud and overheating—a common failure point on standard ATVs.
- Snorkeled V-Twin & CVT Inlets/Outlets: The engine and CVT air intakes, along with the CVT exhaust, are routed up to the highest point of the machine. This allows you to go deep without worrying about sucking water into your engine or drowning your drive belt.
- Aggressive Mud-Ready Tires: From the factory, the XMR comes equipped with ITP Cryptid tires specifically designed for mud. They feature aggressive, self-cleaning lugs that bite hard and paddle through the slop.
Visco-4Lok Front Differential
The Visco-4Lok front differential is a game-changer. With the push of a button, you can engage a true, fully-locked 4-wheel drive system. This means all four wheels turn at the same speed, providing maximum possible traction when you’re axle-deep and fighting for every inch of forward progress.
Your Essential Can-Am Outlander 850 XMR Care Guide
A machine that plays this hard requires diligent care. Following these Can-Am Outlander 850 XMR best practices will dramatically extend its life and prevent costly repairs. This is the most important part of ownership.
Pre-Ride Checks: The 5-Minute Lifesaver
Before every single ride, take five minutes to perform a quick walk-around. It’s the cheapest insurance you can buy.
- Check Fluids: Verify your engine oil and coolant levels. A low coolant level is a major red flag for overheating.
- Inspect Tires: Look for any punctures and check the air pressure. Proper pressure ensures optimal traction and prevents bead breaks.
- Test Brakes: Squeeze the brake levers to ensure you have firm pressure. Check your brake fluid reservoir level.
- Wiggle Everything: Gently wiggle your handlebars, wheels, and A-arms. You’re feeling for any loose bolts or worn-out bushings that could cause problems on the trail.
- Look for Leaks: Do a quick scan underneath for any dripping fluids.
Post-Mud Bath: The Crucial Cleanup Routine
What you do after the ride is just as important. Letting mud dry and cake onto your machine is a recipe for disaster. It traps moisture, accelerates corrosion, and hides potential problems.
Use a pressure washer, but be smart about it. Avoid spraying directly into electrical connections, bearings, or radiator fins. A good foam cannon and a soft brush can help loosen caked-on grime. Pay special attention to cleaning the radiator, suspension components, and the undercarriage.
Fluid Finesse: Oil, Coolant, and Differential Fluids
Your owner’s manual is your best friend here, but for extreme use, consider shorter service intervals. Use a high-quality oil like XPS 5W-40 Synthetic Blend.
After a ride with deep water crossings, it’s wise to check your front and rear differential fluids for a milky appearance. This indicates water contamination, and the fluid must be changed immediately to prevent catastrophic gear failure.
Common Problems with Can-Am Outlander 850 XMR (and How to Fix Them)
No machine is perfect. Being aware of the common problems with Can-Am Outlander 850 XMR models allows you to be proactive and catch issues before they leave you stranded. Honesty about these issues is key to trustworthy ownership.
Overheating Woes: Keeping Your Radiator Happy
Even with its relocated radiator, the XMR can overheat if the rad gets clogged. Fine mud and grass can get past the screen. After every muddy ride, gently rinse the radiator fins from the back side to push debris out the way it came in. Never use high pressure directly on the fins, as you can easily bend them.
Belt Blues: Recognizing and Preventing CVT Belt Failure
The CVT (Continuously Variable Transmission) belt is a wearable item. Signs of a failing belt include a burning smell, loss of power, or jerky engagement. The number one killer of belts is heat. Avoid prolonged high-RPM, low-speed situations. When tackling technical terrain or deep mud, always use Low range to keep the belt cool and provide maximum torque.
Electrical Gremlins: Fuses, Connections, and Battery Care
Mud and water are enemies of electricity. A common issue is corrosion in electrical connectors. Periodically unplug key connections, clean them with an electrical contact cleaner, and apply a dab of dielectric grease before reconnecting. This simple step can prevent a world of frustration.
Performance Mods: Benefits of a Can-Am Outlander 850 XMR Upgrade
The stock XMR is incredible, but there are always ways to make it better. The primary benefits of a Can-Am Outlander 850 XMR upgrade are tailoring the machine to your specific riding style and enhancing its durability and capability.
Tires and Wheels: The Foundation of Your Ride
While the stock tires are great, you might want something more aggressive or a different size. Be cautious when going much larger, as it puts extra strain on your axles, drivetrain, and belt. If you upgrade tires, a clutch kit is highly recommended.
Clutch Kits: Fine-Tuning Your Power Delivery
A clutch kit is one of the best “bang-for-your-buck” mods. It involves changing the springs and weights inside your CVT clutches. A good kit, like those from EPI or Dalton, will re-engage your belt at a higher RPM, preventing belt slippage and giving you snappier throttle response, especially with larger tires.
Lighting and Winches: Enhancing Capability and Safety
Good lighting is a safety essential. Upgrading to an LED light bar makes night riding infinitely safer and more enjoyable. A quality winch (like a Warn VRX 35) is non-negotiable for a mud machine. It’s not a matter of if you’ll get stuck, but when.
How to Can-Am Outlander 850 XMR: Riding Tips for Trail & Mud
Knowing how to Can-Am Outlander 850 XMR properly will make you a better, safer rider. This machine has immense power that demands respect.
Mastering the Mud: Techniques for Deep Holes
Momentum is your friend. Approach a mud hole with steady, consistent speed. When you’re in it, stay on the throttle. If you feel the tires start to spin without moving forward, gently rock the handlebars side-to-side to help the lugs find new grip. If you get stuck, don’t keep spinning—that just digs you in deeper and overheats your belt. It’s time for the winch.
Trail Etiquette and Safety Best Practices
Always wear a helmet and appropriate safety gear. Ride with a buddy, stay on designated trails, and be courteous to other riders. Pack a basic tool kit, a tire plug kit, and a first-aid kit. Your XMR is capable, but preparation is what will get you home safely.
Sustainable & Eco-Friendly Can-Am Outlander 850 XMR Riding
Being a powerful off-roader comes with responsibility. Practicing sustainable Can-Am Outlander 850 XMR riding ensures our trails stay open for generations to come. It’s about being a good steward of the sport.
Treading Lightly: Minimizing Your Impact
The core principle of eco-friendly Can-Am Outlander 850 XMR riding is to stay on the trail. Avoid creating new bypasses around obstacles or mud holes, as this causes erosion and trail widening. Cross streams only at designated crossings to protect fragile ecosystems.
Proper Fluid Disposal and Maintenance
When you perform your own maintenance, collect all used fluids (oil, coolant, gear lube) in sealed containers. Take them to your local auto parts store or municipal recycling center for proper disposal. Never, ever dump fluids on the ground or down a drain.
Frequently Asked Questions About the Can-Am Outlander 850 XMR
What kind of fuel should I use in my 850 XMR?
The Can-Am Outlander 850 XMR is designed to run on premium unleaded gasoline with an octane rating of 91 or higher. Using a lower octane fuel can lead to engine knocking and reduced performance.
How often should I change the CVT belt?
There is no set mileage. Belt life depends entirely on riding style. A good practice is to inspect your belt every 50 hours of use. If you ride hard in the mud, you may want to carry a spare belt and the tools to change it on the trail.
Is the 850 XMR good for anything besides mud?
Absolutely! While it’s a mud specialist, the Outlander chassis, powerful engine, and comfortable ride make it a fantastic all-around trail machine. It excels at rock crawling, hill climbs, and general trail riding, though the aggressive mud tires may offer a rougher ride on hardpack trails.
