Trail, motocross, and electric dirt motorcycles are the three varieties of 50cc dirt bikes available.

Because of its modest speed of 15 mph, the Razor Dirt Rocket SX500 electric dirt bike is an excellent entry-level alternative for youngsters. On the plus side, it is permitted to ride on the street and is safe to do so in the area. Electric bikes, on the other hand, are too sluggish for anything thrilling like racing or trail riding, and your youngster may outgrow it fast.

Beginner riders prefer the 50cc trail dirt motorcycles, such as the Honda CRF50F and Yamaha TTR50E, since they have adjustable speed restrictions that allow kids to get used to riding dirt bikes safely.

Depending on the type and size of the bike, trail dirt bikes have maximum speeds ranging from 25 to 40 miles per hour.

Mini trail motorcycles with a low seat height, such as the Yamaha PW50, have a speed range of 20 to 28 mph and are suited for children aged 4 to 6.

For larger 5- to 7-year-old children, the Honda CRF50F has a 3-inch taller seat and a much greater maximum speed of 35 mph.

Because of its greater peak speed of 45 mph and a larger seat height appropriate for bigger youngsters, motocross bikes like the KTM SX50 Mini are perfect for kids with riding expertise. Due to its lightweight structure and suspension system, it also offers greater handling, making it a perfect choice for introducing kids to motocross racing.

Which is the Safest Speed for Kids?

Before you get too worked up over how fast your child’s bike is going, make sure they’re wearing enough safety gear. Dirt motorcycles have the potential to go out of hand, so make sure your kids are fully protected.

Even if your children don’t want to reach top speeds, it’s still crucial to keep them safe. Do not introduce the sport to extremely young children. They should be at least 5 or 6 years old.

Show them how to get into second gear and make it obvious that they should not go any farther. Their bike will be restricted as a result of this action. You can avoid showing them how to shift into third gear for your own peace of mind.

Falling is also less deadly when driving in second gear. When learning to ride a dirt bike, children will undoubtedly fall a lot. To assure their safety, install a throttle limiter as well.

Having a dirt bike capable of high speeds comes with its own set of dangers. Amateur motorcyclists are prone to what is known as “Whiskey throttle.” It happens when a motorcyclist pulls back on the throttle and becomes afraid of the speed, causing them to freeze.

The youngster may be unaware that they should let off of the throttle to slow down the bike, and the excessive speed leads them to collide with obstruction and fall.

Choose an easy-to-use throttle limiter like the Yamaha TTR50, which has a bolt that juts out under the throttle that you screw in.

Is Dirt Biking a Safe Sport for Children?

There is no such thing as a risk-free hobby. Dirt biking appeals to parents because it allows their children to spend time outside while learning new skills. Dirt riding is one of the strategies to provide a healthy and enjoyable childhood for our children.

Expect a sprained ankle and a fractured bone, albeit you should take additional precautions to keep them safe.

The next question is how to make dirt bike riding safe. Children above the age of six should be able to participate in the thrilling sport of dirt biking.

Keep the dirt bikes clean and well-maintained so that your children are always riding in a safe vehicle.

Additionally, trail riding should be monitored at all times. You might also incorporate the following safety tips:

  • During each session, all children should be outfitted with protective gear including a helmet. To provide a good example, you should be equipped with the same.
  • Encourage your children to ride dirt bikes on authorized dirt bike paths and off-road. Jumps should be avoided since they might be difficult for children.
  • Starting with a two-wheeler is a good place to start. It is a prevalent misconception that four-wheelers are safer, but facts show that this is not the case.
  • Set a speed restriction and install a throttle limiter.
  • Dirt bike riders should be accompanied by an adult.

Our family’s choices for keeping the kids safe are as follows. My boys adore dirt riding, and I’ve found it to be quite beneficial to them. It has toughened them up because dirt riding entails falling and suffering bruises and scratches. I enjoy pushing my sons to do new hobbies, such as dirt riding, that stretch them but don’t overextend them so they stay motivated. Now that my boys have begun dirt riding, they are more confident, which means it has been a success for our family.

Factors Affecting Dirt Bike Speed

While engine capacity is the primary determinant of motorcycle speed, other factors can influence how quickly your 50cc dirt bike can travel. One consideration is the dirt bike’s weight. In comparison to a heavier model, lighter dirt motorcycles, such as the Yamaha PW50, are faster and easier to control.

Type of Engine

Specifications of dirt bikes, such as engine type and sprocket gearing alterations, can have an impact on the motorcycle’s performance and speed.

2-stroke engines are often significantly quicker and lighter than 4-stroke engines, making them suitable for dirt bike motocross racing. A 4-stroke dirt bike, on the other hand, has a wider power range, which requires less gear shifting and is easier to handle for beginner riders.

Gear Ratio

The gear ratio is another component that influences speed. You can increase the dirt bike’s performance and average speed by modifying the sprocket gearing, which you may do by adjusting the gear ratio.

The goal is to boost maximum speed when racing and obtain a competitive edge without sacrificing low-end torque acceleration. The size of the front and rear sprockets in relation to each other is referred to as gear ratio.

For example, you may gear up or down by replacing the dirt bike’s front or rear standard sprockets with a bigger or lower tooth sprocket to attain the desired speed.

A smaller rear sprocket increases peak speed whereas a bigger rear sprocket increases acceleration but reduces maximum speed.

How to Design a 50cc Dirt Bike to go Faster?

Following the techniques below, you may make some modifications to your 50cc dirt bike to make it move faster:

  • Get the exhaust pipe and muffler off of the car and clean them. The exhauster may be cleaned using a cleaning rug, and carbon by-products can be removed by shaking the muffler. The accumulation of residual carbons in these components obstructs the airflow, which is necessary for proper motor performance.
  • With the impact wrench or the socket wrench, remove the revolution restriction. Because the exact position varies by brand and model, it’s best to consult the handbook. To extend the engine’s lifespan, the limiter guarantees that the engine does not power the bike over a certain speed. The speed limitation on 50cc dirt motorcycles is set to 30 mph.
  • Replace the oil in your motorbike with 100% synthetic motorcycle oil. Compared to frequently used oils, the oil is excellent for cooling and lubrication. When riding a 50cc motorbike at higher speeds, it’s critical to keep the bike cool for both safety and performance.
  • Choose a fuel with a higher octane rating. The ideal octane gasoline for every dirt bike model is determined by the model and make. Despite the fact that higher-octane fuel improves a bike’s performance. You may try out a few different types to discover which one appeals to you the most.
  • V-notch spark plugs should be used instead of factory spark plugs. The former style of plugs ignites more quickly, increasing your bike’s speed.
  • Drill a few small, accurate holes in the air intake box of the bike. The airflow in the system will be increased as a result of this activity. When used in conjunction with the previous stages, this can increase performance even further.
  • Any additional pipes and hoses that may have gathered residue should be cleaned. Inspect the bike to confirm that all of the parts are in good working order and that it functions properly.

While increasing the speed of your dirt bike might be enjoyable, there are certain rules to follow.

The safety of modifications to boost the speed of a 50cc dirt bike cannot be guaranteed. Any configurations should be done with prudence, as well as a thorough study of your individual model and brand.

Before you ride, double-check your parts to make sure they’re in working condition. Most manufacturers’ warranties will be voided if you modify your dirt bike.

Modifying a dirt bike may cause it to be classified as a small motorcycle, requiring a license. Any specs you would need to know can be found at the DMV.

Which is better for kids: a new dirt bike or a used dirt bike?

If your child is just five or six years old when they begin riding dirt bikes, you will most likely go through many bikes before they reach adolescence.

For safety reasons, a child should ride a bike that is appropriate for their size. As a result, children must change bikes as they grow older.

Dirt bike riding is hardly the most inexpensive activity available. However, getting into the sport without breaking the money is feasible. Purchasing a new bicycle provides a number of benefits.

The model will be covered by warranty, and within the first six months of ownership, some degree of service is usually offered.

The bike will be in fine shape, and you may easily resale it at a reasonable market price if they outgrow it.

If you’re on a tight budget, check for a secondhand dirt bike to get your kids started with. Perhaps you believe that the sport is only a passing interest for your children, and you are unsure whether or not you should invest much money in it.

Because dirt bike communities are often small, you may ask around for recommendations. Some setups or parts upgrades may be required for a secondhand bike.


For good reason, most parents are hesitant to allow their children to ride dirt motorcycles. Dirt riding comes with its own set of dangers, and it’s only normal to be apprehensive of risky activities.

To answer your worry regarding how fast a 50cc dirt bike runs, a 50cc dirt bike’s average speed range is between 25 and 40 mph, which some parents believe is too fast for their children. However, we’ve included some suggestions for lowering the speed restriction to make it easier for your child to ride the bike until they get more expertise.

If you’re still worried, start your little rider on an electric bike, which goes at a considerably slower 15 miles per hour and is, therefore, safer for youngsters than gas-powered bikes. Furthermore, by providing your children with safety equipment, you can ensure that they ride safely and reduce the severity of their injuries in the event of an accident. hopes you find the most suitable option!
