The Pre-Ride Inspection: Your 10-Minute Safety Checklist

The most important maintenance you’ll ever do is the one you perform before every single ride. This simple routine can save you from a catastrophic failure miles from the truck. These are the 2021 Can-Am Maverick X3 Max DS Turbo best practices that every owner should live by.

Check Your Fluids: Start with the engine cold. Pull the dipstick to check the engine oil level. Then, check the coolant in the overflow reservoir. Make sure both are between the “min” and “max” lines.
Inspect Tires and Wheels: Look for any cuts or punctures in the tires. Check your tire pressure and adjust it for the terrain you’ll be riding. Grab each wheel at the top and bottom and try to wiggle it—any play could mean a bad wheel bearing or ball joint.
Look for Leaks: Scan the ground under your machine. Look for any drips of oil, coolant, or gear fluid, especially around the engine, transmission, and differentials.
Test Your Brakes: Before you even start the engine, press the brake pedal. It should feel firm, not spongy. Once running, roll forward a few feet and test them again.
Examine Your CVT Belt and Housing: Take a quick look at your CVT exhaust vent. Is it clear of mud and debris? While you don’t need to pull the cover every time, being mindful of your belt is crucial.
Check Your Air Filter: If you ride in dusty conditions, your air filter is your engine’s only defense. Unlatch the airbox cover and take a peek. If it’s caked in dirt, clean or replace it. A clogged filter kills performance and your engine.

Common Problems with the 2021 Can-Am Maverick X3 Max DS Turbo (And How to Fix Them)

No machine is perfect. After spending countless hours in the shop and on the trail, we’ve seen a few recurring issues with these rigs. Knowing what to look for can save you a massive headache down the road.

The Infamous CVT Belt

The number one failure point on any high-power UTV is the CVT drive belt. The 120 HP X3 is easier on belts than its more powerful siblings, but heat and improper use are still the enemy.

The Problem: Glazing, shredding, or outright breaking a belt, leaving you stranded.
The Solution: Always use low gear when driving under 20 mph, especially when rock crawling or loading onto a trailer. This keeps belt temps down. Carry a spare belt (we recommend a quality aftermarket one like a Gates G-Force) and the tools to change it. A pro tip is to periodically remove your CVT cover and blow out all the belt dust with compressed air.

Suspension and Steering Wear

With 20 inches of travel, the suspension components take a beating. Tie rods, ball joints, and A-arm bushings are common wear items.

The Problem: Sloppy steering, clunking noises over bumps, or uneven tire wear.
The Solution: During your pre-ride check, specifically look for play in these components. A good set of aftermarket, high-clearance A-arms and beefier tie rods are excellent upgrades for aggressive drivers. Regular greasing of all zerk fittings is a must.

Heat Management

The turbocharged Rotax engine generates a lot of heat, especially in the cab area. While the 120 HP model runs cooler than the 172/195 HP versions, it’s still something to be aware of.

The Problem: Uncomfortable cab temperatures, especially on slow, hot rides.
The Solution: Ensure your radiator is clean and free of mud. An aftermarket fan override switch can be a useful tool for pre-cooling the engine before a hard climb. Some owners also add heat shielding to the panels between the engine and the cab.

DIY Maintenance: A Practical 2021 Can-Am Maverick X3 Max DS Turbo Care Guide

Ready to get your hands dirty? This is how to 2021 Can-Am Maverick X3 Max DS Turbo maintenance is done right in your own garage. Following the service intervals in your owner’s manual is key, but these are the big three you’ll be doing most often.

Engine Oil and Filter Change

This is the lifeblood of your engine. Regular oil changes are cheap insurance against engine wear.

Gather Your Tools: You’ll need a drain pan, a funnel, a ratchet with an 8mm and 17mm socket, a torque wrench, a new oil filter (like the XPS 709000841), and about 2.2 quarts of 5W-40 synthetic oil meeting API SN standards.
Warm It Up: Run the engine for 2-3 minutes to warm the oil, which helps it drain completely.
Drain the Old Oil: Place the drain pan underneath. Remove the 17mm drain plug from the bottom of the engine and let the oil drain fully.
Replace the Filter: Use your 8mm socket to remove the three bolts on the oil filter housing. Swap the old filter for the new one, making sure to replace the O-ring.
Refill and Check: Reinstall the drain plug and torque it to spec (18 ft-lbs). Add the new oil through the fill port. Start the engine, let it run for 30 seconds, shut it off, and then check the level on the dipstick, adding more if needed.

Air Filter Service

In the off-road world, clean air is just as important as clean oil.

Access: The airbox is easily accessible in the bed of the machine. Unclip the cover.
Inspect: Carefully remove the air filter. If it’s just dusty, you can tap it out on a hard surface (tap the clean side, so dust falls out, not in). If it’s oily or caked with fine silt, it’s time for a replacement.
Clean the Box: Before installing the new or cleaned filter, wipe out the inside of the airbox with a clean, damp rag to remove any settled dust. This is a critical step many people miss!

Smart Upgrades: Enhancing Your Ride

The stock 2021 Can-Am Maverick X3 Max DS Turbo is a fantastic machine, but a few key mods can make it safer, more durable, and even more fun. Here are our top picks.

Safety First: Harnesses and Roof

The factory seatbelts are adequate, but 4 or 5-point harnesses will keep you and your passengers much more secure in rough terrain. An aluminum or plastic roof is another must-have for protection from the sun and elements.

Durability Mods: Skid Plates and Guards

The factory underbelly protection is minimal. A full set of UHMW (Ultra-High Molecular Weight) plastic skid plates will protect your frame, engine, and drivetrain from rock damage. A-arm guards are another smart investment.

Sustainable 2021 Can-Am Maverick X3 Max DS Turbo Choices

Thinking about a more eco-friendly 2021 Can-Am Maverick X3 Max DS Turbo setup? It’s less about emissions and more about longevity and reducing waste. Investing in high-quality, reusable air filters (like those from S&B or K&N) can reduce waste over the life of the machine. Similarly, choosing durable, well-made parts that won’t need frequent replacement is a sustainable practice that also saves you money in the long run.

Frequently Asked Questions About the 2021 Can-Am Maverick X3 Max DS Turbo

What is the real-world top speed of the X3 Max DS Turbo?

From the factory, the 120 HP 2021 Can-Am Maverick X3 Max DS Turbo is electronically limited. Most owners report a top speed right around 65-70 mph on a flat surface. An ECU tune can easily remove this limiter, but that may impact your warranty.

How often should I change the CVT belt?

There’s no hard-and-fast rule, as it depends heavily on your riding style. As a preventative measure, many aggressive riders change their belt every 800-1000 miles. For casual trail riding, you can go much longer. The best practice is to carry a spare and know how to change it on the trail.

What is the best fuel to use?

The Rotax 900cc turbo engine requires premium unleaded gasoline with a minimum octane rating of 91. Using a lower octane fuel can lead to engine knocking, reduced performance, and potential long-term damage. Always use premium fuel.

Your 2021 Can-Am Maverick X3 Max DS Turbo is an incredible piece of engineering built for making memories. By taking the time to understand it, perform regular checks, and tackle basic maintenance, you’re not just protecting your investment—you’re ensuring every ride is as safe and thrilling as the last.

So grab your tools, follow these 2021 Can-Am Maverick X3 Max DS Turbo tips, and get ready for your next adventure. The trail is waiting. Stay safe and ride on!
