Most dirt bikes with a 70cc engine are capable of speeds of up to 40 mph. On the other hand, your bike’s top speed will be affected by several variables, such as the surface you’re riding on, the rider’s weight, and the strength of the engine. Some 70 cc dirt bikes may reach speeds of up to 50 mph.

If you’re just getting started on dirt bikes, a 70cc model is perfect. Those who have never ridden a bike before may appreciate these models’ manageability and small weight. Perhaps you’re curious, though: “How quick is a 70cc dirt bike?”

To find out how fast a 70cc dirt bike can go, keep reading!

How Fast is a 70cc Dirt Bike?

A 70cc dirt bike may go at speeds between 30 and 50 miles per hour, depending on several conditions. You should expect your bike’s top speed to be influenced not just by your own physical attributes but also by the terrain you’re traveling over and the strength of its motor.

Different 70cc dirt bikes have different top speeds; some can go as fast as 50 mph thanks to their lightweight and high horsepower, while others may only be able to go as fast as 30 or 40 mph.

Factors that Determine the Speed of a 70cc Dirt Bike

Several factors can affect the speed of your 70cc dirt bike. These include:

The type of terrain you’re riding on

Your bike’s speed will be reduced from what it would be on flat ground if you’re riding over bumps or hills. The 70cc bike I rode on both types of terrain convinced me there was a distinction.

The weight of the rider

To put it simply, a heavier rider will slow the bike down compared to a lighter one. The reason is a heavier rider will put extra strain on the bike’s engine, making it work harder and reducing its speed.

The power of the engine

When comparing two motorcycles, the one with the stronger engine will be the faster of the two. It’s because of this some 70cc dirt bikes can hit speeds of 50 mph while others might only be able to reach 30 or 40 mph.

Rider experience

The rider’s level of expertise might also have a role in the motorcycle’s top speed. An expert rider can keep the bike under tighter control, resulting in higher speeds, while a less skilled rider may slow it down.


The tires on your bike can affect its speed, which is something you might not think about right away. A vehicle with wider tires can travel faster on sandy or muddy surfaces.

Narrower tires will aid speed, though, if you’re riding on compacted soil or paved surfaces.

Weather conditions

How fast your bike can go depends on a number of factors, including the weather. Your bike’s speed will be reduced in wet or snowy circumstances compared to when the road is dry.

Is it Safe to Ride a 70cc Dirt Bike at Top Speed?

Riding a 70cc dirt bike at peak speed is risky, just like riding any other motor vehicle. Losing control of the bike, colliding with an obstacle, and getting hurt are all possibilities when traveling at high speeds.

You should never ride above your skill level or your physical capacity. If you’re just learning to ride, take it easy at first and build up your pace as your confidence grows.

Ride safely and responsibly at all times, regardless of how fast your bike is.

What is the Safe Speed for a 70cc Dirt Bike?

No matter how large or powerful a motorcycle is, there is always a maximum safe speed. Numerous variables, such as the rider’s skill level, the terrain, and the weather, will determine the maximum safe speed.

When traversing tough terrain, a speed of 30 miles per hour or less is recommended as a general rule. If you’re just starting out as a motorcyclist, it’s smart to keep your speed around 20 miles per hour.

In any situation, it’s better to be safe than sorry, so remember to take things slowly rather than risk going too fast. Maintaining a safe riding speed will keep you out of harm’s way and add to the overall pleasure of your ride.

How Does a 70cc Dirt Bike Compare to Other Dirt Bikes in Terms of Speed?

When it comes to dirt bikes, those with a 70cc engine are somewhat slow. Some dirt bikes, like the 125cc and 250cc models, are significantly quicker.

Still, most riders will find that 70cc dirt bikes offer more than enough speed. Their top speed of 50 mph is more than sufficient for the vast majority of travelers.

A 70cc dirt bike is an excellent choice for racing or trail riding due to its speed. However, you may want to think about a different size if you’re after a bike with even more speed.

It’s also possible to find smaller dirt bikes. One example is the 50cc, which can travel at speeds of up to 30 miles per hour. Children and inexperienced riders who aren’t yet ready for a more powerful bike would benefit greatly from one of these.

You should ride within your ability and never beyond your limits, regardless of the size of the bike you choose.
