When you invest in an ATV, one of the most important considerations is speed. There’s a big difference between an ATV that tops out at 20mph and one that can push 70mph. ATV speed not only informs the type of terrain your ATV can clear but also determines the level of safety an operator can expect.
If you’re in the market for an ATV or simply asking yourself, “How fast does an ATV go,” we have you covered.
Unlocking ATV Speed Potential: Understanding Limits and Possibilities
The engine is pivotal in determining an ATV’s speed. A larger engine equates to more power, which in turn translates to higher speeds. In essence, the engine size of an ATV determines its top speed, with bigger engines offering more torque, especially at higher elevations.
| Engine Size Range (cc) | Typical User | Top Speed (mph) | Horsepower (hp) |
| 50cc to 200cc | Beginners, Young Riders | 15 to 38 | 3 – 25 |
| 400cc to 650cc | Intermediate Riders | Up to 65 (400cc), Up to 71 (650cc) | 25 – 50 (for 400cc to 500cc), 50 – 75 (for 500cc to 700cc) |
| 700cc to 1000cc | Experienced Riders | 75 – 82+ | 75 – 90+ |
Small Engines, Modest Speeds: 50cc to 200cc ATVs
Max speed: 15 to 38 mph
Beginners or younger riders often start with ATVs that house smaller engines (in the 50cc to 200cc range). They typically clock at a maximum speed of 15 to 38 mph.
While these speeds might seem modest, this will feel fast if you are new to ATV riding.
Factors beyond engine size also influence the ATV’s top speed. Tire size, intake, fuel systems, air filters, and brakes can impact how fast a small engine ATV can go.
The X-Pro 110 ATV is a small engine model, meaning it won’t have the fastest ATV top speed–but is still an exhilarating option for beginners and youth.

Mid-Range 400cc to 650cc Engine Power
Max speed: Up to 71 mph
The 400cc to 650cc ATVs fall within the mid-range power band. These machines are built for riders who crave a little more get-up-and-go from their ATVs.
A 400cc ATV can reach top speeds of around 65 mph, while the 650cc can hit top speeds of a whopping 71 mph.
It’s not just about speed, though.
The mid-range ATVs also pack in more horsepower. You’ll get more initial acceleration and better speed on turns. An example of a mid-range ATV is the Suzuki King Quad 400. This model is a good mix of speed, stability, and fuel economy.

700cc to 1000cc High-Performance ATVs
Max speed: 75- 82+mph
High-performance ATVs in the 700cc to 1000cc are built for speed and performance, making them the top choice for experienced riders.
It’s all about the engine.
The bigger the engine, the more air it can push into the cylinders, which makes the combustion process more powerful, delivering more power and top speeds. So, whether navigating steep hills or racing your friends, these high-performance ATVs will ensure you’re leading the pack.

The Influence of Design and Accessories on ATV Speed
Several factors, including engine size, aerodynamic factors, and aftermarket enhancements, determine an ATV’s top speed. Note that speed is tied in closely with performance; an incredibly fast ATV may also have more power for towing and steep climbs, so it’s important to understand the correlation.
Aerodynamic Factors and Speed
As the ATV slices through the wind, its design can impact the amount of resistance it faces. This resistance, known as drag, increases as the ATV’s speed rises, affecting its top speed and fuel efficiency.
A well-designed ATV, with its streamlined shape, can reduce air resistance, thereby boosting its speed. This is particularly useful when riding on open terrains like a salt flat where you can put the pedal to the metal.
Aftermarket Enhancements: Boosting Performance
Aftermarket enhancements can elevate your ATV’s performance to the next tier.
Larger tires can change how quickly the ATV accelerates and its top speed. Meanwhile, an upgraded exhaust system can improve the vehicle’s overall speed by enhancing the airflow, leading to more horsepower and torque.
High-performance air filters also allow more air into the engine, improving the fuel mix for burning. Upgraded air filters also keep the engine safe from debris.
| Enhancement | Description | Cost Range |
| Exhaust System Upgrade | Improves exhaust flow for better performance and sound. | $200 – $600 |
| Suspension Kit | Enhances the ATV’s handling and stability. | $500 – $1,500 |
| Air Filter Upgrade | Increases airflow to the engine for better combustion. | $50 – $150 |
| Tire Upgrade | Improves traction and handling on various terrains. | $200 – $800 per set |
Handling and Safety at High Speeds
Riding the fastest ATV at high speeds is an experience like no other. However, while speed is thrilling, maintaining control and stability at high speeds is crucial for safety.
This is where the importance of good handling comes into play.
ATV tires with stiffer sidewalls usually make it easier to handle (and stay steady at high speeds), allowing you to steer better around corners.
Usually, high-speed ATVs come equipped with anti-sway bars and independent suspension systems, improving stability and adaptability. A definite balance between speed and control needs to be met.
How to Maximize Your ATV’s Speed Safely
Although the thrill of speed is exhilarating, safety should remain paramount. Understanding how to maximize your ATV’s speed safely guarantees an exciting yet secure ride.
Upgrades That Preserve Safety
Upgrading your ATV isn’t the only option for reaching record-high speeds. You can increase the speed of your existing ATV through performance enhancements–without compromising safety.
Brake upgrades, for instance, provide more stopping power, which is crucial when riding at high speeds.
Shock absorbers are another crucial upgrade (For information on the best ATV shocks for trail riding, check out this article). These ATV shocks minimize bouncing and pitching over rough terrain, protecting the vehicle frame from damage and ensuring a smoother ride.
In a similar way, high-quality tires can enhance your ATV’s handling and stability at high speeds, offering better control. Check out ATV.com’s list of top-rated all-terrain ATV tires.
Knowing Your Limits: Speed and Control
Maintaining control while riding an ATV at high speeds is crucial for a safe and enjoyable experience. One way to ensure this is by using speed limiters, which can help keep your speed in check. Note: These speed limiters are recommended for children and pre-teen riders who may struggle to gauge their limits.
Knowing your limits ensures you stay in control, preventing you from pushing too hard. It’s also important to consider factors like:
- stopping distances
- sight distance
- reaction time
- current conditions
- posted speed limits
When deciding how fast to ride, consider lower speeds for safety and control rather than aiming for max speed.
Mastering the balance between speed and control is exactly what to look for in the best ATVs on the market.
Summary
There are no secrets. The fastest ATVs on the market are the Can-Am Renegade X XC and the Polaris Sportsman XP 1000 S.
If you have a desire for speed in your off-road vehicle, you’ll want also to make sure you are storing it properly. With the size of most ATVs, an enclosed 5′ x 20′ storage unit should work to protect the four-wheeler from UV rays, rain, and dust, which can cause damage. Neighbor, a self-storage marketplace, provides safe, nearby, and budget-friendly storage units to keep your new four-wheeler safe.
