How Fast Does a 70cc Dirt Bike Go

Updated on June 16, 2022

The maximum speed of a 70cc dirt bike is roughly 40-45 mph, although it can go up to 50mph in some circumstances if you put a lot of effort into it. Most experienced dirt bike riders, on the other hand, believe that the safest speeds are between 35 and 40 mph.

Factors Influence When Purchasing a Dirt Bike

It’s important to remember your first bike ride. Ensure you’ve made the appropriate decision before making a purchase. A dirt bike is a vehicle that can go everywhere and do whatever you want it to. Dirt bikes, on the other hand, are designed in such a way that the motors can be clearly seen.

It is designed for off-road racing and events. Before you buy your first bike, you need to know a few things.

Dirt bike purchasing decisions are influenced by the following:

Appropriate Age to Start: In this case, age is the most important element. For children ages four to seven, dirt bikes can be fast and dangerous, but most won’t go as fast as they’re rated to go. At the age of four, a child is old enough to use the second wheel.

Cost: The cost of a 70cc dirt bike varies greatly. Maintaining dirt bikes also involves regular fluid checks and oil changes, which the manufacturer will outline. Ensure that any loose bolts are tightened and that there are no leaks. After a muddy ride, it’s also a good idea to clean your bike. These dirt bikes require frugal spending.

Physic of your child: When deciding whether or not to allow your children to participate in the sport, you should be aware of its potential risks. You need to make sure that your children are at the suitable age and have the necessary resources to handle any challenges they encounter. Until the 70cc dirt bikes are more capable of handling the motorcycle, they should be fitted with training wheels.

Outgrowing their Bike: To progress as a young rider, it is vital to improve their bike. Your child’s acceleration speed can be limited by purchasing motorcycles with throttle limiters. 70cc bikes can still be used and ridden far into your child’s teen years.

New or Used: Most kids are responsible and want to improve their riding skills in a safe atmosphere. For more than a decade, these bikes require little to no maintenance. Buying a used 70cc dirt bike isn’t a big deal because they tend to keep their value.

Speed Limit Reason

The speed limit is determined by the amount of effort you put forward. It’s because the 70cc dirt bike requires a lot more energy from you while you’re going at a high rate of speed.

A 3-5-horsepower increase in power is required to make a 70 cc dirt bike go an additional 10 mph faster.

To put it simply, if you go too fast on a 70cc dirt bike, you’re going to hit its limits. That signifies your engine isn’t up to snuff or you don’t know how to take care of it properly.

It’s important to keep in mind that even a 70 cc dirt bike won’t be able to do wheelies if you ride it too rapidly. Wheelies can be done at a maximum speed of 35 mph, which is a lot slower than the dirt bikes seen on television or in movies, but for kids, this is perfectly fine. Wheelies are still a lot of fun at this pace.

Factor Influence on the Speed of Dirt Bike

Many factors influence the speed of the dirt bike.

  1. Weight and Tires
  2. Rider Experience and Skill
  3. Dirt bike brand
  4. Engine type
  5. Personal demographics

1. Weight and Tires: (affect speed)

To get the dirt bike moving at its top speed, factors like the machine’s weight and the rubber on its tyres are critical. They should be able to handle rough off-road conditions, including water and other types of dirt and debris (gravel, sand, and so on). There is a correlation between the size of the tyres and the overall performance.

As a result, they are more aerodynamic than race bikes. The dirt bike’s power-to-weight ratio is critical. The apparent weight of an object increases linearly with its size. In general, lighter tyres roll more quickly than heavy tyres.

So, if the 70cc tyres on your dirt bike are too heavy, try swapping them out for some that are lighter. The speed of a bike is greatly influenced by the diameter of its tyres, which are available from a wide range of manufacturers. As a result, there is no set upper limit.

2. Rider Experience and Skill

It’s critical that you have the skills and self-assurance necessary to operate at high speeds. Riding a dirt bike takes many days of practise to become proficient at. Rather than making decisions, a biker’s experience is important in changing, braking, leaning in turns, and moving at a fair pace.

Other considerations include the weight of the rider and the design of the bike.

3. Engine’ Type:  (4Stroke vs 2 Stroke Dirt Bikes – Which is Faster?)

Dirt bikes can be equipped with either two-stroke or four-stroke motors. Both have positive and negative aspects.

  • Out of the two options, 4-stroke engines are more efficient.
  • 4-stroke engines tend to be heavier, quieter, and more robust.
  • For a novice, two-stroke can be a bit of a challenge.
  • 2-stroke engines are more powerful and efficient. They are a little more difficult to regulate.

4. Brand of Bike: (Effects the top speed)

Bike performance is directly related to the brand of bicycle. There are certain producers who cut costs by using lower-quality, more heavy-duty materials. In the end, this would affect the motorcycle’s top speed.

For a dirt bike to reach its top speed, there are a number of factors, including:

  • Performance-enhancing materials
  • Research and development spending
  • In-depth knowledge and expertise in the construction of dirt bikes

5. Motocross Track Layout (Also Affect Speed)

You should expect a range of speeds based on the surface conditions. What should you keep in mind while building a motocross track for your dirt bike ride? Pavement is what should be used for tracks. The bike’s acceleration is improved because of the smooth ride. If you have a specific model of bike, though, it may not.

What Is The Best 70cc Dirt Bike?

It would be beneficial if you were aware that not all products live up to the expectations set forth by their creators. A 70cc four-stroke engine powers the sportier 70cc dirt bike. Despite its diminutive size, this bike can reach a top speed of 55 kilometres per hour.

Conclusion

It may seem like an insurmountable effort to get your youngster to ride a dirt bike, but it isn’t. Only a dirt bike with a 70cc engine will be able to compete with them.

Doing wheelies and other stunts while riding their new item will make them feel successful and offer them a good time.

. The rapid speed of a dirt bike of this size is another benefit. This is ideal for racing with family and friends who have bikes of a comparable size.

I hope this blog post has given you a better understanding of what type of dirtbike your child should be riding at different skill levels.
