If you’re asking yourself exactly how fast an 80cc dirt bike can go, then you’ve found the right place to look.
The average max speed of an 80cc dirt bike is roughly 45-50 mph. However, an 80cc dirt bike speed can vary when a rider’s weight and if the bike is a 2 stroke or 4 stroke. 2 strokes being the faster of the two. Some sources claim to have reached a speed of 85 mph.
Of course, there are many factors that can affect the speed of an 80cc dirt bike.
How Body Weight Affects Speed
In the world of dirt biking, rider weight plays a crucial role in speed dynamics. Common wisdom suggests that every additional 7 lbs may slow you down by the equivalent of 1 horsepower. This difference becomes especially pronounced when comparing, for example, a 200 lb adult to a 100 lb teenager – the impact on speed and agility can be significant.
Contrary to popular belief, 80cc dirt bikes aren’t just for kids; they offer a thrilling experience for adults as well. Many adults opt for these nimble machines not just for their young riders but for their own enjoyment too. These bikes pack enough punch to conquer hills and provide an exhilarating ride. While heavier adults may not match the velocity of lighter riders, the joy and excitement of riding remain undiminished.
For individuals weighing under 150 lbs, the 80cc dirt bike might be a perfect fit. Designed with lighter riders in mind, these bikes offer a comfortable ride without the risk of bottoming out the shocks with every airborne moment. On the other hand, heavier riders might prefer a bike with more robust suspension, such as a 250cc model, to navigate diverse terrains smoothly and comfortably.
It’s also worth noting that 80cc dirt bikes are a popular choice among youngsters, with kids as young as 7 to 10 years old embarking on their dirt biking adventures. These bikes serve as an excellent introductory model for beginners and come with the added advantage of being more budget-friendly compared to their larger counterparts.
2 Stroke V. 4 Stroke
The easiest way to explain it is a 2 stroke hits hard and fast while a 4 stroke allows the rider to have more control over how the bike rides. It’s definitely a preference of the riders based on the feel of the ride they are seeking.
2 Stroke bikes are always going to be faster than a 4 stroke of the same cc. Without getting too technical, a two stroke has twice as many ignition strokes as a 4 stroke. They are louder, faster, and a little less controllable.
A 2 stroke has more power and energy, which can be fun, but for a beginner, it can be intimidating. Young riders, unless experienced, probably shouldn’t practice with a 2 stroke just because the additional oomph factor it has compared to the 4 stroke.
Also good to note that a 4 stroke engine is the more efficient option of the two. 4 stroke engines are heavier, quieter and often more durable. Contrarily, the 2 stroke emits a high pitched buzzing sound while riding.
Let’s just say, if I were to recommend a bike to my female friend who has little to no experience with dirt biking, then I’d suggest the 4 stroke. The reason behind that is because the 2 stroke can be a bit intense for a beginner. Granted, if thrill and excitement is the goal behind riding then the 2 stroke is, in my opinion, the better choice.
Increasing Speed on a 80cc Dirt Bike
One way to increase the speed of the dirt bike is to maintain the parts. For example, the obvious musts are to change the air filter, change the oil, and check the coolant levels.
Upgrading the type of gas can also help with speed as well. The VP Racing’s Ultimate 4 race track fuel is recommended.

Also, the 43 mm front fork has a totally unique air spring design.

Hard Terrain V. Track Riding
Exploring the contrast between track and off-road biking reveals a unique rider experience. Dirt bikes aren’t designed for sustained high-speed runs. Pushing the engine too hard can lead to significant wear and tear. These bikes excel at navigating jumps and uneven terrain, prioritizing fun and skillful maneuvering over sheer speed.
Built for off-road adventures, dirt bikes navigate dirt paths and rocky landscapes with ease. Their rugged tires and sturdy build aren’t crafted for speed racing; they’re about mastering the art of off-road riding. If speed is your main thrill, a dirt bike might not align with your goals.
Mastering the balance between standing and sitting while riding on rough terrain enhances the overall experience. Standing lowers the bike’s center of gravity, offering a smoother ride and conserving the rider’s energy. The real joy in dirt biking lies in overcoming obstacles, whether it’s perfecting a sharp turn or executing a flawless jump.
Proper bike setup is crucial, especially when tackling diverse terrains. Ensuring that handlebars, gear shifters, and rear brakes are tailored to the rider’s comfort can significantly enhance the biking experience.
While an 80cc dirt bike typically reaches speeds of 45-50 mph, many riders keep it below 35 mph. On smoother tracks or downhill paths, speeds might spike to 60-85 mph, but these instances are brief and not the core of dirt biking. The essence of dirt biking lies in the thrill of pushing limits and embracing the adventurous spirit of off-road challenges.
