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

Typically, the lighter the rider weighs, the faster they will go. It's generally tossed around that +7 lbs = 1 hp slower and vice versa. It might not seem very significant but if you're talking about a 200 lb man, vs a 100 lb teen it can be substantially different.

While a lot of people think the 80cc dirt bikes are for kids, they are actually fun for adults too. In fact, many adults purchase them for themselves rather than for their children. They have enough power to get over hills and play around. Although a full-grown adult isn't going to have the speed of a smaller rider, there is still plenty of fun to be had.

The 80cc dirt bike also might be easier to handle for someone weighing under 150 lbs. They are going to be more comfortable since they are designed for people of that size. The shocks aren't going to bottom out every time you get any kind of air. Heavier riders would want more suspension, probably at least a 250cc dirt bike, to travel across different terrains comfortably.

For reference, kids as young as 7-10 years old ride 80cc dirt bikes. They are a great starting bike for beginners and are much less pricey than 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.

If you're looking for the fastest dirt bike around 80cc, look no further than the KTM 85 SX Dirt Bike The KTM 85cc dirt bike is a 1 cylinder, 2 stroke engine is probably the best option and is undoubtedly the most powerful engine of it's kind. It retails at just under $6,000 but it's many features make it well work it.

Every detail of the bike is designed with performance and image in mind. It's best known for winning lot's of competitions. It's bright orange paint color and fresh graphics give it the perfect image for racing. The shape of the bike is super sleek and modern.

One neat feature is that the cylinder is designed with a unique valve system to increase torque and assist with controlling the bike. The bike also houses two radiators, with integrated crank house cooling systems, for high performance. The frame is also designed for top performance.

Another really cool feature that sets this bike apart is the unique technology behind the rear shocks which works to provide the ultimate in shock absorption and stability. Also, the 43 mm front fork has a totally unique air spring design. It not only allows for easy adjustments to any track conditions but it's also ideal to adjust with different rider weights and skill levels.

Hard Terrain V. Track Riding

Riding on a track versus rough terrain can greatly affect the experience of the rider.

Dirt bites typically are not intended to be driven at the highest speed for long periods. Not to mention the fact that high speeds can be hard on the engine of the bike and cause a lot of wear and tear. Dirt bikes are really meant for taking jumps and balancing on rough roads. The goal isn't usually to ride as fast as possible, just to have fun and play around with different challenges.

Dirt bikes are truly intended to be driven off roads. They are designed to ride over dirt road and rocks. The tires on dirt bikes are more rugged and durable to withstand the different terrains. The function of the bike is not to master racing so if your goal is to reach the highest speeds then the dirt bike might not be the best choice.

It's a good idea to master standing while riding on rough terrains. Figuring out when to stand and when to sit will not only help with conserving energy, but it will also make the experience more pleasant. Standing also lowers the center of gravity which can make the bike ride smoother. Again, a lot of the fun in riding dirt bikes is about the challenges that come along it. Figuring out how to make a turn or how to make a jump is the fun part of the ride.

Along with that, having the bike set up properly for the type of terrain your riding on is really important as well. Making sure the handlebars, gear shifter, and rear breaks are positioned comfortably for the rider is a great start.

Average speeds on an 80cc dirt bike are 45-50 mph and a lot of riders don't exceed 35 mph. On a smooth track or going downhill it's possible to reach speeds up to 60-85 but it's somewhat unlikely and it typically doesn't last long. Again, the goal of the dirt bike isn't really to hit high speeds. It's fun to push the bikes a bit to see what they can do but that's about it.
