Dirt bikes can be considered one of the best inventions of mankind. The thrill of riding a bike through swerving lanes and dirt trails, the split-second rush of jumping over a hurdle, and the first time you achieve a perfect wheelie are just some of the moments that riding a dirt bike will make your experience. Some people are born to ride. The ground is their canvas to paint on, and the bike, their brush.
But every artist has to start somewhere. 50 cc bikes are specifically aimed at beginners, children, and adults alike. They are encouraged to try out their passion for driving on a 50 cc bike. Ask every racer; their first bike would have most probably been a 50 cc engine that they can probably draw from memory alone.
A 50cc bike is a low-power bike that would be perfect, to begin with for children and young teens. It is a relatively safer option as the power capacity is low and is best suited to start your journey into the world of dirt bikes.

Factors Influencing the Speed of a 50 cc Bike
There exist several factors that play a critical role in influencing the speed of your bike. We have listed down a few of them for your perusal
4-Stroke vs 2-Stroke engine
Perhaps the most important aspect of a bike is its engine. This factor directly influences the speed of your vehicle. A powerful and smooth-run engine can help you gain speed, and the opposite is an unkept engine, slowing you down.
It is a primary feature of dirt bikes used in reference to the engine type that your bike contains. The upward and downward movement of the pistol in the engine is called a stroke.
Two-stroke engines have a quicker initial acceleration, are easier to fix and repair, and run on a fuel mixture of oil and gas, making their emissions fairly dirty. Four-stroke engines, on the other hand, offer higher top speed. And contain complicated engines, and run cleaner than a two-stroke.
The 4-stroke dirt bike
A four-stroke dirt bike, as the name suggests has four strokes( up and down movement of the piston in the engine) involved in the movement of the engine. These steps are as follows: intake, compression, combustion, and exhaust. With a manageable power output, reduced shifting, these bikes are easy to ride. Their limitations include their expense and maintenance.
The 2-stroke dirt bike
A two-stroke dirt bike, true to its name requires two strokes( up and down movement of the piston in the engine) involved in the movement of the engine. These bikes can cover the need for a four-step word within the span of two strokes. The two-stroke bikes are lightweight, easy to maintain, and cheaper than their counterpart. However, they require regular maintenance and cause a lot of pollution in the environment.

Weight of the Bike
When you’re riding a bike, it is obviously important to consider how heavy the vehicle is gonna be. This is an often overlooked feature in dirt bikes as riders tend to forget to correlate the weight of the bike with themselves. Most 50 cc bikes are lightweight due to their target audience. However, it is better to be safe than sorry. Depending on your strength and use for the bike, it could be better to compare the weight of the bike prior to purchase. Furthermore, the speed of your dirt bike gets reduced, the heavier your vehicle is as more power is spent on heaving the bike, rather than increasing the speed.
Size of the Rider
The height and weight of the rider is an important factor that majorly influences the functioning of the bike. As in the case of the weight of the bike, with increased body weight, the chances of speeding reduces. The rider needs to select a bike that is best suited to his/her needs. Choosing a bike that is too tall or short, tends to create problems. The ideal height ratio is to get a bike that lets you place your feet fully on the ground, with no problem. This height will give you the perfect leverage while handling your bike and prevents the beginners from toppling over, as they can balance the bike when it shifts sideways.
Wind Drag
Something to do with the aerodynamics, the wind drag is yet another overlooked factor. Drag is the force of wind or air resistance pushing in the opposite direction to the motion of the object. Which basically refers to the forces of wind acting for and against the biker.
Rear Sprocket
The official definition of a sprocket is as follows: Sprockets are used in bicycles, motorcycles, tracked vehicles, and other machinery either to transmit rotary motion between two shafts where gears are unsuitable or to impart linear motion to a track, tape, etc.
Therefore, substituting a larger front or smaller rear sprocket lowers the ratio, resulting in more speed for a given engine rpm. Likewise, a smaller front or larger rear sprocket gives less speed for a given rpm. So, size does not matter.
Experience
Now, the experience and skill of the rider matter a lot in influencing the speed, efficacy, and overall driving of the vehicle. And since this article focuses on 50 cc bikes that are used by beginners, it is safe to say, that practice is the key to success. And, the first goal should be to ride the dirt bike in a safe and disciplined manner, rather than focusing on speed.
When the rider gets a basic understanding of riding the bike, patience, dedication, and hard work will ultimately improve the rider’s level of skill.
The Track Layout
The layout of the track also helps determine the speed of the bike. Different tracks offer different potentials for speeding. The tracks can be natural, muddy, rough, terrain, rugged, artificial, or a combination of many. Each of these tracks allows the rider to ride at varying speeds.

Frequently Asked Questions
What factors affect the speed of a dirt bike?
There are many different types of physical and environmental that affect the speed of a dirt bike like the engine of the dirt bike ( 2 strokes or 4 strokes), Weight of the bike, wind drag, rear sprocket, height and weight of the rider, the experience and skills of the rider and the type of motocross track layouts.
Does riding a dirt bike require a license?
You do not need a license or license plate number to ride a dirt bike. But it’s important that the rider is above the age of 16 in order to ride a dirt bike on a public road.
At what age can a kid ride a dirt bike?
Even a four-year-old can start riding an electric dirt bike. You can start training a kid with a 50cc Dirt bike at the age of 4 and can remove the training wheels after practice and improvement.
2 Stroke vs 4 Stroke – Which is Best for Beginners?
The choice between 2-strokes and 4-strokes will depend on your riding preference.
2-strokes are lighter and easier to ride, and beginners will be able to handle and control them. They are also quick, and they deliver their power at higher revs. It is also easy and cheap to repair 2-strokes, although they need a precise air/fuel blend to perform optimally.
4-stroke bikes are larger than 2-stroke models, and they are more prevalent in motocross. Since they are heavier and taller, beginners may find it hard to control 4-stroke bikes. Overall, 4-strokes are better for long runs.
