How Fast Does A 50cc Dirt Bike Go? Things You Should Know 2022

How fast does a 50cc dirt bike go? A 50cc dirt bike typically has a top speed of between 25 and 30 mph. However, many factors can affect the actual top speed of a particular bike, such as the weight of the rider, the terrain, and the type of bike.

How Fast Does A 50cc Dirt Bike Go?

50cc dirt motorcycles come in electric, motocross, and trail.

Due to its extremely low speed of 15mph, the Razor Dirt Rocket SX500 electric dirt bike is a fantastic entry-level alternative for kids. The good news is that it is legal for the street and secure to ride around the neighborhood. Electric bikes, however, are too slow for anything thrilling, like racing and off-roading, and your child might rapidly outgrow them.

The Honda CRF50F and Yamaha TTR50E are popular alternatives for starting riders because they have adjustable speed restrictions that help kids become accustomed to safely managing dirt bikes.

Depending on the type and size of the bike, the top speed for trail dirt motorcycles ranges from 25 to 40 miles per hour.

Young children between the ages of 4 and 6 should be able to ride mini trail motorcycles with a low seat height, like the Yamaha PW50, which has a speed range between 20 and 28 mph.

For older children aged 5 to 7, the Honda CRF50F sports a seat that is 3 inches taller and has a much higher top speed of 35 mph.

Kids with riding experience should use motocross bikes like the KTM SX50 Mini since they have a higher top speed of 45 mph and a higher seat height suitable for larger children. However, because of its lightweight design and suspension system, it also has greater handling, making it a great option for introducing kids to motocross racing.

Factors Affecting Dirt Bike Speed

Factors Affecting Dirt Bike Speed

While a motorcycle’s engine size mostly determines its top speed, your 50cc dirt bike’s top speed can also be influenced by other factors. The dirt bike’s weight is one of the factors. In contrast to a heavier model, lighter dirt bikes, like the Yamaha PW50, are quicker and easier to control.

Engine type

The engine type and sprocket gearing alterations on dirt bikes can also affect the motorcycle’s performance and speed.

When compared to 4-stroke engines, 2-stroke engines are frequently faster and lighter, making them perfect for motocross racing dirt bikes. A 4-stroke dirt bike, on the other hand, has a wider power band, which necessitates less gear shifting and is simpler for novice riders to control.

Gear Ratio

The gear ratio is another element that affects speed. By altering the bike’s gear ratio, you can vary the sprocket gearing and raise the performance and average speed of the dirt bike.

Without sacrificing low-end torque acceleration, the goal is to raise the peak speed and obtain a competitive edge while racing. The size relationship between the front and rear sprockets is referred to as the gear ratio.

For instance, to gear up or down to obtain the desired speed, you may swap out the factory front or rear sprockets on the dirt bike for ones with more or fewer teeth.

A larger rear sprocket will increase acceleration but decrease peak speed, whilst a smaller rear sprocket will increase top speed.

Make sure your child is wearing enough safety gear before worrying about the speed at which their bike is going. Dirt motorcycles have the potential to get out of control, so you must take precautions to keep your kids safe.

Even if your children don’t try to reach top speeds, it’s still crucial to stopping this from happening. Don’t introduce the sport to very young children. They should be at least five or six years old.

Make it plain that they should not go past the second gear as you lead them into it. This action will severely restrict their bike. You can choose not to demonstrate how to engage the third gear for your own peace of mind.

Additionally, falling is less dangerous when driving in second gear. Kids who are learning to ride a dirt bike will inevitably fall a lot. To protect their safety, also include a throttle restriction.

Owning a dirt bike with the ability to travel at high speeds comes with its own set of dangers. Sometimes, novice riders fall victim to the so-called “Whiskey throttle.” It happens when a motorcyclist pulls back on the throttle and freezes up out of fear from the speed.

The child may not always be aware that they should release the throttle to allow the bike to slow down, and the high speed can cause them to crash into something and lose their balance.

Choose a throttle limiter that is simple to install, such as the Yamaha TTR50, by screwing in the bolt that protrudes under the throttle.

Can You Limit the Speed on a 50cc Dirt Bike?

Can You Limit the Speed on a 50cc Dirt Bike

Choose dirt bike models with a modest top speed, like the Yamaha PW50, if you are worried about how fast your child will be riding it.

However, you may get a dirt bike with a throttle limiter and kill switch for safety if the child is a little older and more daring.

Let’s examine below how each of these aspects functions.

Throttle Limiter

A throttle limiter feature reduces the turning radius of the throttle to limit the amount of power above a certain speed. The speed limitation keeps riders at a safe speed as they build proficiency and confidence on their dirt motorcycles.

Additionally, it aids in the 2-stroke dirt bike’s power delivery being more linear, which helps the young rider accelerate easily over uneven terrain. A throttle limiter is a standard feature on most 50cc trail bikes whereas it is an optional feature on some motocross bikes.

Your tiny dirt bike’s throttle grip is where the throttle limiter is positioned. You start by unscrewing the two bolts on the limiter cover and taking off the throttle grip cover in order to modify the speed restriction.

Then you will notice three smaller screw holes, the first of which has a screw in it. To decrease the throttle’s turning angle and lower the top speed restriction, you should travel to the last hole.

After adjusting, tighten the two bolts to secure the throttle grip cover. As opposed to before, the throttle now makes a half turn instead of opening wide.

Compared to trying to supervise your child to keep their dirt bike in low gear, it is a remarkably easy approach to control how fast they ride. Additionally, you may modify it again with the same ease once they have more riding experience.

Kill Switch

Like the throttle limiter, the kill switch is not a typical feature of 50cc dirt bikes. However, you may find them on large-capacity dirt bikes and install one as an extra safety measure on your child’s dirt bike.

In an emergency, the kill switch aids in the quickest possible engine shutdown of the motorcycle. Due to its location on the dirt bike’s handlebars, it is easier to access and functions in the same way as the ignition key.

On the other hand, a flat battery could be caused by failing to turn off the ignition when the dirt bike is parked or turning on the kill switch while the ignition is on. On your child’s dirt bike, a kill switch offers an emergency stop option in case they lose control of the machine.

When the kill switch is pressed while the motorcycle is moving, the engine’s power is withdrawn, and the dirt bike gradually loses speed until it comes to a stop.

The following steps can be used to make some adjustments so that a 50cc dirt bike moves more quickly:

  • Clean the muffler and exhaust pipe after retrieval. The exhauster can be cleaned using a cleaning rug, and any carbon byproduct can be removed by shaking the muffler. The accumulation of leftover carbons in these parts blocked ventilation, which is essential for effective motor activity.
  • With the socket or impact wrench, remove the revolution restriction. It is a good idea to consult the manual as the exact location depends on the brand and model. In order to prolong the engine’s life, the limiter makes sure that the bike can’t be driven beyond a certain speed. The limiter on 50cc dirt bikes restricts speed to 30 mph.
  • Replace the oil in your motorcycle with synthetic motor oil. Compared to other oils, this oil is more suited for cooling and lubrication. When riding a 50cc motorbike faster than its top speed, a good cooling system is crucial for both performance and safety.
  • Choose higher-octane fuel. Although higher-octane gasoline improves a bike’s performance, the ideal octane fuel for each dirt bike model often differs depending on the type and make. You can experiment with many types to determine which ones you like the most.
  • V-notch spark plugs should be used instead of the original ones. Older plugs spark more quickly and will increase your bike’s speed.
  • Make a few small, exact holes in the air intake box of the motorcycle. The system’s airflow will be improved by taking this measure. If combined with the previous steps, this can further enhance performance.
  • Any more lines and hoses that may have gathered debris should be cleaned. Verify that the bike is functioning properly and that all the parts are properly assembled.

While increasing the speed of your dirt bike can be entertaining, there are several rules you should follow.

It cannot be assured that a 50cc dirt bike will always be safe after modifications to improve speed. Implementing any settings requires caution in addition to thorough research of your particular model and brand.

Prior to riding, make sure all of your parts are checked again to ensure they are in working order. Most manufacturer warranties will be voided if you modify your dirt bike.
