The debate around quads vs. dirt bikes is an age-old one. People usually side with one or the other because a lot of things are subjective when it comes to these two offroad rides. However, there’s a clear answer if we wish to compare their speed.
Dirt bikes are faster than quads because they are lighter and can take sharp turns more quickly. Even if a dirt bike and a quad have the same engine, the bike has a better power to weight ratio, which makes it accelerate much faster than an ATV with the same motor.
ATVs don’t always perform slower than dirt bikes, though. Read on to learn more about their speed, whether faster speed means less safety with dirt bikes, and how you can choose which one is best for you.
Why Are Dirt Bikes Faster Than ATVs?
The most significant factor that makes dirt bikes go faster than quads is weight. A sport ATV can weigh twice as much as a dirt bike. An average dirt bike weighs around 215 lbs (98 kg), while you can expect an average ATV to weigh 590 lbs (268 kg). That’s only an estimated average; the actual weight will depend on the size of your engine (cc). But overall, two-wheelers are much lighter than four-wheelers.
This lighter weight allows dirt bikes to move more quickly and effectively in narrower spaces than quads. Also, you’ll be able to climb hills faster on dirt bikes.
As we’ve discussed, ATVs and dirt bikes have the same engine—weight is what makes all the difference. Imagine two vehicles: a quad weighing 400 lbs (181 kg) and a dirt bike weighing 230 lbs (104 kg). If they have the same engine, which one will go faster? Of course, the dirt bike as it can accelerate more quickly than four-wheelers, thanks to its greater power to weight ratio.
With that said, ATVs don’t lose all the time when it comes to speed. Dirt bikes have two wheels, and quads have four, which means they have more traction. Because of this, they can perform better on muddy, slick tracks and flat tracks.
Theoretically, quads would have more acceleration than a dirt bike if the power to weight ratios were equal. I’m saying this because they have more contact patch (the amount of tire touching the ground). Their extra weight also helps traction to some extent.
However, in real life, they have (compared to their heaviness) less power and more weight. So a dirt bike is faster, more maneuverable, and accelerates quicker than a four-wheeler. Of course, a lot of it also depends on the rider.
Advantages of Higher Speed
Since dirt bikes are so fast and convenient, they’re often used in racing and sport. On the other hand, ATVs are heavier and not suitable for high-speed racing. Riders can also perform more stunts and tricks on dirt bikes. In contrast, it can be dangerous to do the same on ATVs, especially for inexpert drivers.
This brings me to another point: dirt bikes give you more adrenaline rush than ATVs. Their higher speed and better flexibility offer a more thrilling adventure. I’m not saying ATVs aren’t fun, they are, but you would have to be an excellent rider to drive them at high speeds. Whereas dirt bikes naturally offer the thrill of jumping off hills and going super-fast.
Does This Mean Dirt Bikes Are Less Safe?
We’ve talked about high speeds, stunts, and hill-climbing. While that’s cool and all, there’s another critical matter to discuss: the level of safety.
This may seem obvious at first. Dirt bikes go faster, and people perform more stunts on them, so they’re more prone to accidents, right?
Well, yeah, quads are involved in fewer accidents, but there’s more to it. And if you believe ATVs are safer than dirt bikes, you’re in for a surprise.
A John Hopkins study shows that dirt bikes are safer than ATVs. Riding ATVs causes a lot more deaths than riding two-wheelers. To give you the stats, quad-crash victims are 50% more likely to die. They’re also 55% more likely to be admitted to the intensive care unit (ICU) and 42% more likely to be placed on a ventilator.
But ATVs are more stable and comfortable to ride for beginners. Why these surprising results? Quads are undoubtedly steadier than dirt bikes. The stability of ATV gives people a false sense of security. As a result, they try to corner too fast or ride on uneven tracks.
However, the center of gravity of ATVs is too high, so they’re likely to flip over. Remember that there’s no crash protection for the rider, so an ATV rolling over you can be extremely dangerous.
If you were in a bike accident, you could get away with strains and sprains, and you’ll probably be thrown off the bike. You may still break a bone, but it’s nothing compared to an ATV accident.
If you were riding a quad and got into an accident, its massive weight could break your neck or back, resulting in death. Even if you’re lucky, the chances of you getting injured severely are very high.
The bottom line? Dirt bike accidents happen more often than ATV accidents. Still, the latter can be much more fatal, which means dirt bikes are overall safer.
Choosing Between ATVs and Dirt Bikes
If you’re looking to get a new off-road companion for yourself, speed and safety aren’t the only factors to consider. There are many things you need to look for when comparing a dirt bike with an ATV. Here are some important ones:
- Learning: If you’re a beginner, a dirt bike can seem more intimidating, and there’s also a learning curve involved. ATVs are more beginner-friendly and are forgiving for kids.
- Comfort: Quads have a larger seat than dirt bikes. Sitting down on a quad is more comfortable than sitting on a dirt bike, which is designed for you to stand up more than sit down. Overall, the ATVs are more comfortable.
- Utility: With ATVs, you can pull and drag heavy machines or a utility trailer. They can also carry passengers, so they’re more functional. Dirt bikes, on the other hand, are usually not used for work.
- Maintenance: An ATV, of the same rider class as a dirt bike, is more expensive. Not only that, but the maintenance costs of ATVs are also higher. So if the price is a concern, a dirt bike is the way to go.
- Convenience: ATVs are restricted to two-track trails only, while you can ride a dirt bike on many tracks. Dirt bikes take up less space, and you can even carry them by yourself if you ever encounter a malfunction. The same cannot be said for ATVs.
To summarize, if you want more out of your vehicle than just thrilling rides, go for an ATV. It can be useful in handling heavy machines and other stuff. But if you’re only looking for breath-taking adventures and unforgettable memories, a dirt bike should be your pick.
When it comes to speed, dirt bikes are faster because they weigh less but have the same power as ATVs. The only exception would be a flat or a muddy track where ATVs could have an advantage because of their increased traction.
Surprisingly, even with higher speeds, dirt bikes have been reported to be safer than ATVs. However, both these vehicles are fun to ride, and you’ll need to choose based on what you want from your ride.
