We’ll cover everything from essential pre-ride checks and routine maintenance you can do yourself, to identifying common problems and implementing best practices for years of trail-shredding enjoyment.

What Makes the 2021 Can-Am Outlander 850 a Modern Legend?

Before we get our hands dirty, let’s appreciate what we’re working with. The 2021 model year solidified the Outlander 850’s place as a top contender in the big-bore ATV world. It’s not just about raw power; it’s about how that power is delivered.

The heart of this machine is the 78-hp Rotax 854cc V-twin engine. It provides a mountain of torque right off the line, making it perfect for rock crawling, mudding, and towing. Can-Am paired this with their signature rider-focused design.

Key Features and Benefits

  • Intelligent Throttle Control (iTC™): This ride-by-wire system gives you three distinct modes (Work, Standard, and Sport), allowing you to tailor the throttle response to the terrain or task at hand. It’s a game-changer for technical riding.
  • Dynamic Power Steering (DPS™): The Tri-Mode DPS offers varying levels of steering assistance. It reduces rider fatigue on long days and prevents handlebar kickback when you hit an unexpected rock or root.
  • Superior Suspension: With arched A-arms and a Torsional Trailing arm Independent (TTI) rear suspension, the Outlander provides a plush ride and impressive ground clearance, keeping the frame rails clear of obstacles.
  • Visco-Lok QE Front Differential: This system automatically locks the front differential quickly when it senses wheel slip, giving you true four-wheel-drive traction exactly when you need it.

Your Pre-Ride T-CLOCS Inspection: The 5-Minute Safety Habit

Every great ride starts with a quick but thorough inspection. Don’t skip this! Catching a small issue in the garage can prevent a major failure on the trail. We use the T-CLOCS checklist, a system familiar to motorcyclists and just as crucial for ATVs.

T — Tires & Wheels

Check your tire pressure. The recommended PSI is printed on the tire sidewall and in your owner’s manual. Look for any cuts, punctures, or embedded objects. Grab each wheel and check for any side-to-side wobble, which could indicate a bad wheel bearing or loose lug nuts.

C — Controls & Cables

Test your throttle; it should snap back cleanly when released. Squeeze your brake levers; they should feel firm, not spongy. Check your gear shifter and 4WD selector to ensure they move smoothly through their positions.

L — Lights & Electrics

Turn the key and test your headlights (high and low beams), taillights, and brake lights. Check the dash display for any warning lights. A quick check now prevents you from getting caught on the trail after dark with no lights.

O — Oil & Fluids

This is critical. Check your engine oil level using the dipstick. Inspect the coolant level in the overflow reservoir and check the brake fluid reservoir on the handlebars. Look for any drips or leaks under the machine.

C — Chassis & Suspension

Visually inspect the frame for any cracks or damage, especially after a rough ride. Look at your CV boots (the rubber accordion-like boots on your axles) for any tears. A torn boot lets dirt in and grease out, quickly destroying a CV joint.

S — Stands (or in our case, Stance)

Take a final walk around the machine. Is everything secure? Are your rack accessories tightened down? Does anything look out of place? This final once-over is your last chance to spot something amiss.

A DIYer’s 2021 Can-Am Outlander 850 Care Guide

Proper maintenance is the single most important factor in your ATV’s longevity. Following this 2021 can am outlander 850 care guide will save you a fortune in shop bills and prevent breakdowns. Always consult your owner’s manual for specific service intervals.

Changing the Engine Oil and Filter

This is the most common maintenance task and one of the most important. The Rotax V-twin works hard, and clean oil is its lifeblood.

  1. Warm up the engine for a few minutes to get the oil flowing.
  2. Place a drain pan under the engine and remove the drain plug. Let the old oil drain completely.
  3. Remove the old oil filter. A cap-style filter wrench makes this easy.
  4. Wipe the filter mating surface clean and apply a thin layer of new oil to the gasket of the new filter.
  5. Install the new filter and tighten it hand-tight plus another quarter turn. Do not overtighten!
  6. Reinstall the drain plug with a new sealing washer and torque it to the factory spec.
  7. Refill with the recommended oil (like XPS 5W-40 Synthetic Blend) to the level indicated on the dipstick.

Air Filter Service

Your ATV breathes through its air filter. A dirty filter chokes the engine, robbing it of power and efficiency. The Outlander’s airbox is conveniently located under the seat.

Simply remove the cover, take out the foam filter, and wash it in warm, soapy water. Rinse it thoroughly and let it dry completely. Once dry, apply a quality foam air filter oil, working it in until the foam is evenly coated. Reinstall, and you’re done.

CVT Belt and Housing Check

The Continuously Variable Transmission (CVT) uses a drive belt to transfer power. Inspecting it periodically is one of the most crucial 2021 can am outlander 850 tips we can offer.

Remove the plastic CVT cover. Blow out any dust and debris with compressed air. Inspect the belt for any glazing, cracking, or missing cogs. If you see any signs of significant wear, it’s time for a replacement before it fails on the trail.

Common Problems with the 2021 Can-Am Outlander 850 (And Their Solutions)

No machine is perfect. While the Outlander 850 is incredibly reliable, there are a few common issues to be aware of. Knowing what to look for can turn a potential trip-ending problem into a simple fix.

Overheating

Symptom: The temperature light comes on, or you see steam coming from the engine bay.

Cause: The most common cause is a mud-caked radiator. The radiator needs clean airflow to cool the engine. A failing fan or low coolant can also be the culprit.

Solution: First, let the machine cool down completely. Then, thoroughly clean the radiator fins with a garden hose (not a high-pressure washer, which can bend the delicate fins). Check your coolant level and ensure the cooling fan kicks on when the engine gets hot.

Starting Issues

Symptom: You turn the key and get a click, a slow crank, or nothing at all.

Cause: This is often a weak or dead battery. Corroded battery terminals or a faulty starter solenoid can also be to blame.

Solution: Start with the basics. Ensure your battery terminals are clean and tight. Use a multimeter to check the battery voltage; a healthy battery should read around 12.6 volts. If the battery is good, you may need to investigate the starter solenoid and connections.

Spongy Brakes

Symptom: The brake levers feel soft and travel almost to the handlebars before engaging.

Cause: This is almost always caused by air in the brake lines.

Solution: You need to bleed the brakes. This process pushes fresh brake fluid through the lines, forcing any air bubbles out. You’ll need a friend to help pump the brakes while you open and close the bleeder valve on the brake caliper. It’s a simple but vital safety procedure.

Sustainable Off-Roading: Eco-Friendly Best Practices

Being a true off-roader means being a steward of the trails we love. A sustainable 2021 can am outlander 850 experience is about responsible ownership. It’s not just about being green; it’s about preserving access for future generations.

Adopting eco-friendly 2021 can am outlander 850 habits is easy. It starts with proper maintenance. A well-tuned engine burns cleaner and is less likely to leak fluids on the trail. When you change your oil or other fluids, always dispose of them properly at an auto parts store or local recycling center.

Frequently Asked Questions About the 2021 Can-Am Outlander 850

What is the top speed of a 2021 Can-Am Outlander 850?

While Can-Am doesn’t officially publish a top speed, most stock Outlander 850s can reach speeds of 70-75 mph in ideal conditions. However, these machines are designed for trail performance and torque, not top-end speed runs.

What kind of fuel should I use in my Outlander 850?

The 2021 Outlander 850 is designed to run on regular unleaded gasoline with an octane rating of 87 or higher. Using higher octane fuel will not harm the engine but typically provides no performance benefit in a stock machine.

How often should I service the differential and transmission fluids?

According to the manufacturer’s service schedule, you should inspect the fluid levels at every service interval. It’s recommended to change the front differential, rear differential, and gearbox oil after the initial break-in period and then approximately every 200 hours or 3,000 miles, whichever comes first.

Can I install a winch on my Outlander 850 XT?

Absolutely. The XT, XT-P, and other premium trims often come with a winch pre-installed. If yours didn’t, Can-Am and many aftermarket companies offer model-specific winch mounting plates that make installation a straightforward, bolt-on job. A winch is one of the most valuable upgrades you can make.

Your 2021 Can-Am Outlander 850 is an incredibly capable and rewarding machine. By understanding its systems, performing regular maintenance, and practicing responsible riding, you’ll ensure it’s ready for any adventure you can dream up. Now, get in the garage, get your hands a little dirty, and get ready for your next ride.

Stay safe, and happy trails!
