Fuel-Injected ATVs: Are They Superior? Top 4 Picks!

Manufacturers like Yamaha, Honda, and Can-Am are always looking for new ways to innovate their engines to improve performance. The latest stride they made in terms of boosting engine efficiency was introducing fuel injection systems. Thanks to this, most four-wheelers use EFI (electrical fuel injection) systems. The trick is to know how to pick the right ones.

Fuel injected ATVs are so much better than carburetor ATVs that EFI (electronic fuel injection) systems are considered standard on modern ATVs. Fuel injected ATVs improve the performance of the engine while also lowering the chances of running too rich or lean, therefore taking the mileage of EFI quads to the next level. Furthermore, the best fuel injected ATV is the Polaris 450 Sportsman that uses a 500cc liquid-cooled four-stroke engine.

Whether you want to find out the benefits of running a fuel injected or carburetor ATV, I have the answers you are looking for. I’ll go over the pros and cons, but that’s not all. I will also give an in-depth preview of the best fuel injected ATVs on the market.

How Do Fuel Injected ATVs Work?

Fuel injection in ATVs has redefined performance and efficiency by providing a more precise way to deliver fuel to the engine. Instead of relying on the vacuum created by the engine, as carburetors do, fuel injection uses pressurized injectors. Here is a quick breakdown that explains how the entire process works:

  • Sensors & ECU: Various sensors around the ATV monitor parameters like air temperature, throttle position, and engine load. This data is sent to the Electronic Control Unit (ECU), which calculates the optimal amount of fuel the engine needs.
  • Fuel Delivery: Based on the ECU’s calculations:
    • The fuel pump pressurizes the fuel.
    • Fuel injectors then spray the determined amount directly into the combustion chamber.
  • Feedback & Adjustment: A crucial component is the oxygen sensor in the exhaust. It provides feedback to the ECU about the air-to-fuel mixture. If it was too rich or too lean during combustion, the ECU adjusts in real-time, ensuring optimal efficiency.

This streamlined process ensures that the ATV’s engine receives the precise amount of fuel it needs for varying conditions, enhancing performance and fuel efficiency.

ATV Fuel Injection vs Carburetor: Which One is Better?

Truth be told, fuel injection and carburetor ATVs have their fair share of pros and cons. This is why I am going to present a full pros and cons comparison so that you can make the right decision when buying your next ATV.

Fuel Injected ATVs


  • Precision: Electronically controlled, ensuring the right amount of fuel for optimal performance.
  • Adaptable: Adjusts to different conditions such as altitude and temperature automatically.
  • Fuel Efficiency: Generally offers better mileage and less wasted fuel.
  • Emissions: Tends to produce cleaner emissions, adhering to tighter environmental standards.
  • Cold Starts: Starts up more easily in cold conditions.


  • Cost: Typically more expensive initially and can be pricier to repair.
  • Complexity: More electronic components which may need specialized knowledge to repair.

Carbureted ATVs


  • Simplicity: Easier to understand, adjust, and repair, often without specialized tools.
  • Cost: Generally less expensive initially and cheaper parts available.
  • Tried and True: Has been around for decades and many mechanics are familiar with them.


  • Adjustments: Requires manual adjustment for different conditions (e.g., altitude).
  • Fuel Efficiency: Not as efficient, may waste more fuel.
  • Cold Starts: Might face challenges starting in cold weather.

As we can see, the pros of fuel injected ATVs highly outweigh the cons. Fuel injection offers a more modern, efficient, and adaptable system, especially for diverse and challenging conditions. The improved performance is just too good to overlook.

Top 4 Best Fuel Injected ATVs

As I was writing this article and doing my research into fuel injected ATVs, I couldn’t help but notice that there is a handful of models that stand out among the rest. With that said, I have prepared the top 4 best fuel injected ATVs on the market. I will give you a full preview of their top features and what makes them stand out. That’s not all. I will also present their cons. Without any further ado, let’s jump right into it.

#1 Polaris Sportsman 450

Polaris 450 Sportsman

The Polaris Sportsman 450 is such a great four-wheeler that it’s featured on almost all “top x ATV” lists. I am not kidding. The ATV is even featured in two of my articles. The top 3 cheapest four-wheelers and the top 3 best 450 sport ATVs. If you take a look at the specs and features that the Polaris Sportsman 450 offers, you will quickly see why it holds the title of being one of the best four-wheelers on the market.

The ATV is available at an entry-level price that starts at $6,249 and it comes with a slew of features such as an electric fuel injection system, a 500cc engine that puts out 33HP, 25” 6-ply tires, 1,350 lb. towing capacity, and automatic transmission. Another important feature that makes the Polaris Sportsman 450 a great choice is the sealed dual A-arm rear suspension that makes riding the four-wheeler a smooth experience.

#2 Yamaha Raptor 700R

Yamaha Raptor 700R

If the Sportsman 450 doesn’t impress you, then the Yamaha Raptor 700R will get it done! This is another famous ATV that you can always find on mountain trails and muddy roads. The reason behind this is that the Yamaha Raptor 700R is super versatile and that its 686cc four-stroke engine delivers more than enough power to deal with rugged terrains. Whether you are riding in the forest or on the country roads, you will feel safe and in control of the Yamaha Raptor 700R.

The powerful engine delivers 40HP (which is a lot for a quad!) and it reaches a top speed of around 85mph. Since the topic is ATVs that use fuel injected systems, no one should be shocked that the Yamaha Raptor 700R uses a specialized EFI that provides the engine with the perfect amount of fuel it needs to run at peak levels. Although, I do need to mention that there is a downside to Yamaha Raptor 700R’s design. The ATV comes with a small fuel tank size of 2.9 gallons. If you go for long rides, you might bring along an extra can of fuel.
