If you’re a fan of dirt biking, you probably already know that 80cc dirt bikes are the most popular for beginners and casual riders. These smaller-sized bikes are perfect for having fun in the dirt, but how fast can they really go? Let’s break down some facts about 80cc dirt bikes and find out!
What Is an 80cc Dirt Bike?

An 80cc dirt bike is a type of off-road motorbike with an engine typically ranging from 50 to 125cc. That means it has a small engine compared to other types of motorbikes. This makes them ideal for beginner or casual riders who haven’t yet built up enough experience and skill to handle more powerful motors.
How Fast Does an 80cc Dirt Bike Go?
The top speed of your average 80cc dirt bike is around 30 mph. Some models may exceed this number slightly, but 30 mph is a good estimate. It’s worth mentioning that many factors can affect the maximum speed of a dirt bike, such as its weight, the terrain it’s ridden on, and even its rider’s size and skill level. With that said, 30 mph is about as fast as you should expect your average 80cc dirt bike
Is an 80cc Dirt Bike Right for Your 10-Year-Old?
An 80cc dirt bike is a great way to introduce your 10-year-old to the world of off-road biking. It’s smaller, lighter and more maneuverable than a full-size bike, making it easier for your child to handle. But is an 80cc dirt bike really the best choice for a 10 year old? Let’s take a look at some of the pros and cons of this type of bike so you can decide if it’s the right fit for your child.
Pros
The most obvious benefit of an 80cc dirt bike is its size. This type of bike is smaller than its larger counterparts, allowing your child to easily handle it with less risk of getting out of control. This makes it ideal for younger riders who may not be ready for the power and speed of a full size bike yet. Another pro is that these bikes are often cheaper than their larger counterparts, making them more accessible to families on a budget.
Cons
One potential downside to an 80cc dirt bike is that they don’t have as much power or speed as larger bikes do. If your kid wants to go faster or compete in races, they may need something bigger eventually. Additionally, these bikes are usually only suitable for riding on smooth terrain; anything more challenging may require a bigger, sturdier machine. Finally, even though these bikes are smaller and lighter than their larger counterparts, they still require regular maintenance like any other motorcycle does in order to keep them running properly and safely.

What Kind of Performance Do You Get From an 80cc Dirt Bike?
The performance you get from riding one of these bikes depends on what kind of model you opt for. Generally speaking, however, most models offer decent acceleration and torque that make them great for recreational use. You can expect them to perform well on flat surfaces like roads or trails but will struggle when climbing hills or tackling obstacles like jumps or steep inclines.
4 Stroke vs 2 Stroke 80cc Dirt Bikes
Four-Stroke Engines

Four-stroke engines are the most common type of engine found in dirt bikes today. This type of engine is designed to be simple yet reliable; it features four separate parts (intake, compression, power, exhaust) that work together in succession as the piston moves up and down within the cylinder. This makes them relatively low maintenance compared to two-stroke engines. They also tend to be quieter than two-stroke engines due to their less aggressive combustion process. The downside is that they are typically heavier than two-strokes, which may make them slower on track or trails with a lot of tight turns or hard acceleration points.
Two-Stroke Engines

Two-stroke engines are generally more powerful than four-strokes because they use fewer moving parts and cycle through twice as many strokes per revolution as a four stroke engine does. This means they produce more power in less time, making them ideal for riders who require quick acceleration when racing or riding offroad trails. However, they do require more frequent maintenance due to increased wear on internal components such as bearings and seals due to their higher RPMs during operation. They also tend to be louder than four strokes due to their accelerated combustion process.
Factors that affect the speed of an 80cc Dirt Bike
Engine Size and Type

The size and type of engine plays a role in determining how fast your bike can go. A bigger engine will have more power output and thus have greater acceleration capacity than a smaller engine. The type of engine also matters; two-stroke engines are generally lighter and more powerful than four-stroke engines, which are heavier but more efficient. If you want to get more speed out of your 80cc dirt bike, consider upgrading its engine size or changing its type from four-stroke to two-stroke.
Weight and Aerodynamics
Another factor that affects speed is weight; the heavier the bike, the slower it will be. To make your bike as light as possible, consider replacing its heavy components with lighter ones such as titanium or aluminum parts. Additionally, aerodynamic drag plays an important role in how fast your bike can go; reducing friction by streamlining the body design can help increase speed significantly. So if you’re looking for maximum speed on your 80cc dirt bike, minimizing both weight and aerodynamic drag is essential.
Tire Pressure & Tread Patterns
The pressure in your tires can also affect performance; having too much air pressure will decrease traction while having too little air pressure will reduce stability on corners. To maximize performance, make sure that you adjust tire pressure according to the terrain you are riding on and keep an eye on tread patterns; wider patterns increase traction but decrease rolling efficiency while narrower patterns provide higher rolling speeds but less grip when cornering hard.
How to make your 80cc Dirt Bike go Faster?
Upgrade Your Fuel System
If you want to give your engine an extra boost, consider upgrading your fuel system. Installing larger jets or replacing the carburetor with an aftermarket model can increase air-fuel flow and improve overall performance. It’s important to note that these modifications will require some expertise and may void any existing warranties on your bike, so it’s best to consult a professional before making any changes.
Install a Performance Exhaust System
Installing a performance exhaust system is one of the quickest and easiest ways to improve power output on any bike. Performance exhaust systems are designed to reduce backpressure in the engine while increasing air flow, which helps create more power and torque. Additionally, installing a performance exhaust system can also help reduce heat build-up in the engine compartment, leading to improved performance over time.
Replace Your Intake Manifold
Replacing your intake manifold can also help improve airflow into your engine and increase horsepower. A new manifold will allow more air into the combustion chamber which can lead to increased acceleration and overall power output. It’s important to note that when replacing an intake manifold it is best done with the assistance of a professional mechanic as incorrect installation could lead to damage or even total failure of the engine.
Where can you buy these used 80cc Dirt Bikes?
Private Sellers
The first place you should start looking is in your local classifieds or online marketplace such as Craigslist or Facebook Marketplace. Private sellers often have great deals on used motorcycles and they’re usually willing to negotiate on the price. You can even sometimes find private sellers who are willing to offer financing, making it much easier to buy the bike of your dreams. However, do be careful when buying from a private seller; it’s important to make sure the bike isn’t stolen or damaged beyond repair before committing to any purchase.
Dealerships
If you don’t feel comfortable buying from a private seller, then another option is a dealership. Dealerships have certified mechanics on-site who can inspect the bikes before you buy them and also offer warranties that protect you from any unforeseen problems with the bike down the line. The downside is that dealerships tend to have higher prices than private sellers since they have overhead costs like rent and salaries for their staff.
Online Retailers
Another option is online retailers like eBay or Alibaba. These sites offer a wide variety of used motorcycles at varying prices, so if you want more options than what local dealerships are offering this could be a good choice for you. Plus, many online retailers offer free shipping so that could save you money in the long run. The downside here is that it may be harder to assess the condition of the motorcycle since all of your research will need to be done online instead of in person at a dealership or private seller’s location.
Conclusion:
An 80cc dirt bike is the perfect choice for beginner and casual riders looking to have some fun in the mud without getting too crazy with power and speed. While they may not be able to reach high speeds compared to larger engines, they offer just enough power to provide an exciting ride while keeping things safe—and that’s always important when it comes to any type of motorized vehicle! So if you’re in the market for a new set of wheels, consider looking into some options for an 80cc dirt bike!
