What Makes the 2017 Can-Am Outlander 450 a Modern Classic?

Before we dive into the nuts and bolts, let’s appreciate what we’re working with. The 2017 model year was a sweet spot for the Outlander 450. It sits on the G2 chassis, a significant upgrade that offers superior handling and a more comfortable ride than older models.

The heart of this beast is the Rotax 427cc single-cylinder engine. It’s liquid-cooled and fuel-injected, delivering a punchy 38 horsepower. This isn’t a fire-breathing race quad; it’s a torque-focused engine designed for reliability and utility.

Key Benefits of the 2017 Can Am Outlander 450

Understanding the strengths of your machine helps you use and maintain it better. Here are some of the key benefits you get with this model:

Reliable Power: The Rotax engine is known for its durability. With proper care, it will fire up every time, whether it’s freezing cold or blazing hot.
Comfortable Ride: The Torsional Trailing arm Independent (TTI) rear suspension soaks up bumps like a champ, reducing rider fatigue on long days.
User-Friendly Design: Can-Am put thought into the layout. Accessing the oil filter, airbox, and battery is straightforward, making DIY maintenance much less of a headache.
Versatility: It’s a true do-it-all machine. It’s nimble enough for tight wooded trails but has the grunt and rack capacity for serious work.

The Pre-Ride Ritual: Your Essential Checklist

The single most important habit you can develop is a thorough pre-ride inspection. This five-minute check can prevent a catastrophic failure on the trail and save you from a long walk home. This is one of the most crucial 2017 can am outlander 450 best practices.

We call it the T-CLOCS checklist, a term borrowed from our two-wheeled friends at the Motorcycle Safety Foundation.

T – Tires & Wheels: Check tire pressure (refer to the sticker on your ATV or your owner’s manual). Look for any cuts or embedded objects. Grab each wheel and check for side-to-side play, which could indicate a bad wheel bearing.
C – Controls & Cables: Squeeze the brake levers—they should feel firm, not spongy. Test the throttle; it must snap back smoothly on its own. Check that all cables are routed correctly and not kinked or frayed.
L – Lights & Electrics: Turn the key on. Test your headlights (high and low beams), taillights, and brake lights. Check the 4WD switch and make sure the indicator on the dash works.
O – Oil & Fluids: This is critical. Check your engine oil level on a level surface. Glance at the brake fluid reservoir—the level should be between the min and max lines. Check your coolant level in the overflow bottle.
C – Chassis & Suspension: Look over the frame for any cracks, especially around welds. Check all major nuts and bolts, like your lug nuts and suspension A-arm bolts, to ensure they’re tight. Push down on the racks to check suspension action.
S – Stands (or in our case, Stuff): Make sure your rack-mounted gear is secure. Check that your winch (if equipped) is properly spooled and the hook is secure.

DIY Maintenance Guide for the 2017 Can-Am Outlander 450

Regular maintenance is the key to a long and happy life for your ATV. Here’s how to tackle the most important jobs yourself. Always consult your owner’s manual for specific fluid types and capacities. This is your go-to 2017 can am outlander 450 guide for basic service.

Changing the Engine Oil and Filter

This is the lifeblood of your machine. Plan to do this every 50 hours or at least once a season.

Tools Needed: Ratchet, 17mm socket (for drain plug), oil filter wrench, funnel, drain pan, new oil filter (e.g., K&N KN-152), and 2.1 quarts of 5W-40 synthetic ATV oil.
Step 1: Warm the engine for a few minutes to get the oil flowing.
Step 2: Place the drain pan under the engine and remove the 17mm drain plug. Be careful, the oil will be hot.
Step 3: While it drains, remove the oil filter cover (three 8mm bolts) on the right side of the engine. Use your filter wrench to remove the old filter.
Step 4: Apply a thin film of new oil to the O-ring on the new filter and install it. Reinstall the drain plug (with a new crush washer if possible). Do not overtighten!
Step 5: Add the correct amount of new oil through the fill cap/dipstick hole. Start the engine, let it run for 30 seconds, shut it off, wait a minute, and then re-check the level. Top off as needed.

Cleaning the Air Filter

A clean air filter means a happy engine. Check it after every dusty ride.

How To: The airbox is located under the seat. Simply unclip the lid, pull out the foam filter, and inspect it.
Cleaning: If it’s dirty, wash it with foam air filter cleaner and warm, soapy water. Never use gasoline! Squeeze it dry (don’t wring it out, as this can tear the foam).
Oiling: Once completely dry, apply foam air filter oil evenly. It should be tacky but not dripping. Reinstall, ensuring a good seal around the edges.

Checking Brakes and Drivetrain

Your ability to stop is just as important as your ability to go.

Brake Pads: Visually inspect the brake pads. You should see at least 1/8th inch of pad material. If they’re getting thin, it’s time to replace them.
Brake Fluid: Brake fluid is hygroscopic, meaning it absorbs water over time. Plan to flush and replace your brake fluid (with DOT 4) every two years. If the fluid in the reservoir looks dark or murky, do it sooner.
CV Boots: Check the rubber CV boots on all four axles. Look for tears or cracks. A torn boot lets dirt in and grease out, quickly destroying the expensive CV joint inside.

Troubleshooting Common Problems with the 2017 Can Am Outlander 450

Even the most reliable machines have their quirks. Here are some of the most common problems with 2017 can am outlander 450 models and how to approach them.

Issue 1: Hard Starting or Stalling

If your Outlander is cranking but won’t start, or if it stalls frequently, start with the basics.

Fuel: Is the fuel fresh? Gas can go bad in as little as a month. If it’s old, drain it and add fresh fuel. Check the fuel pump—when you turn the key, you should hear it prime for a couple of seconds.
Spark: A fouled spark plug is a common culprit. Pull the plug (you’ll need a spark plug socket). If it’s black and sooty or wet, replace it with a new one (NGK CR8EB is the stock plug).
Air: We already covered it, but a severely clogged air filter can choke the engine and prevent it from starting.

Issue 2: 4WD Not Engaging

You hit the 4WD button, but only the rear wheels are spinning. This is often an electrical issue.

Check the Fuse: The 4WD actuator has a fuse. Check your fuse box (located under the front storage compartment) for any blown fuses.
Check the Connection: The 4WD actuator is on the front differential. Check the electrical connector going to it. Make sure it’s clean, dry, and securely plugged in. A dab of dielectric grease can help prevent future issues.
The Actuator: If the fuse and connection are good, the actuator itself may have failed. This is a job that may require a professional, but it is a known failure point.

Sustainable Riding: Eco-Friendly 2017 Can Am Outlander 450 Best Practices

Part of being a responsible rider is protecting the trails we love. A few simple habits can make a huge difference, ensuring our riding areas stay open for generations to come. These are key sustainable 2017 can am outlander 450 tips.

First, practice the principles of Tread Lightly! Stay on designated trails, cross streams only at designated crossings, and avoid creating new, erosive paths.

When performing maintenance, think about your environmental impact. Collect all used fluids like oil and coolant in a sealed container. Most auto parts stores will accept used oil for recycling free of charge. Never dump fluids on the ground or down a drain.

A well-maintained machine is also an eco-friendly 2017 can am outlander 450. A clean air filter and proper tire pressure ensure your engine is running as efficiently as possible, burning less fuel and producing fewer emissions.

Frequently Asked Questions About the 2017 Can Am Outlander 450

What is the top speed of a 2017 Can Am Outlander 450?

Stock, a 2017 Outlander 450 can reach speeds of around 50-55 mph. Top speed can be affected by rider weight, tire size, and terrain. It’s designed more for low-end torque and utility than for high-speed runs.

What kind of gas should I use in my Outlander 450?

The Rotax 450 engine is designed to run on regular unleaded gasoline with an octane rating of 87 or higher. Using premium fuel won’t hurt, but it doesn’t provide any significant performance benefit for this stock engine.

How often should I check the valve clearance?

Can-Am recommends an initial valve inspection at the 10-hour break-in service, and then every 100 hours or 1,200 miles thereafter. This is a more advanced job, and if you’re not comfortable with it, it’s best left to a qualified technician.

Can I put larger tires on my stock Outlander 450?

Yes, but with limitations. You can typically go up one or two sizes (e.g., from 25″ to 26″ or 27″ tires) without needing a lift kit or clutch modifications. Going larger will rob power, add stress to drivetrain components, and may require a clutch kit to compensate.

Your 2017 Can Am Outlander 450 is an incredibly capable and rewarding machine to own. By investing a little time in understanding how it works and performing regular maintenance, you’re not just fixing a machine—you’re ensuring countless future adventures. So grab your tools, follow these tips, and ride with confidence. Stay safe out there!
