Factors That Affect The Speed Of A 125cc Dirt Bike

Have you ever joined the dirt bike races? You must have heard chatters and claims about which rider or dirt bike was reckless on a given ground if you have. These bikes come in different sizes and different engine dimensions. However, the average speed of these bikes differs according to engine size, cog gearing, modifications, and many other fundamental factors. Here is a complete description of what limits the speed of dirt bikes, particularly those with 125cc engine size.

1. Load

Similar to cars or other vehicles, the load of a 125cc dirt bike also significantly influences its speed. The maximum load can range from 200 to 250 pounds depending on the model you select. The load rests not only on the weight of the rider but also on the load and the gears of the dirt bike. Many will have several performance promotions that can add to the bike’s weight, reducing it.

2. Environmental Conditions

External factors can also slow down a 125cc dirt bike. For example, its speed will differ significantly depending on the land. The cloudier the terrain gets, the slower the dirt bike will be. The same thing also occurs when you must be aware of many turns and cracks. The wind is another environmental factor that can make your dirt bike gentler. The stormier it is, the more struggle there will be, making it more problematic for the bike to reach its top speed.

However, you might be ignorant, but some of these customizations are a total burden of weight, which disturbs the speed of your 125cc dirt bike.

4. Driver’s Experience

Even if you have the best dirt bike with a top-notch engine, it is hard to reach the top speed when you are inexperienced. If you are new to dirt biking, you are possibly still learning the systems. Not to mention, some may be anxious to rev up the accelerator and reach the supreme speed.

If you newbie you must avoid these common dirt bike riding mistakes.

5. Size Of The Engine

As earlier stated, all types of motorcycles have various engine sizes. This issue is grave for the bike’s speed and horsepower. Regular dirt bikes with engines fluctuate from 50 to 140 cubic centimetres of displacement. Other versions with 175 to 250cc engines are accessible from most builders, but these are far larger than the standard motorbike class that embodies dirt bikes.

Dirt bikes are planned to reach maximum revolutions per minute faster in each gear to keep pace with other types of bikes, such as bit bikes. For a 50cc bike, the top speed can range between 15 to 25 miles per hour when riding in the lower gears. The bike can reach speeds of up to 50 miles per hour or more on longer bounces. When riding in high gear on 125cc dirt bikes with the stock sprocket gearing, you can be supposed to reach a speed of 70moh. As a result, a dirt bike’s engine size is essential in defining its speed.

6. Modifications

Modifications are vital for growing or lessening the speed of your dirt bike. In this regard, increasing speed is the only positive way of looking at it. After all, everyone wants to have their dirt bikes going sensibly faster than their contestants. How will you attain this feat if you increase your bike’s average speed without bargaining its low-end torque acceleration? The answer is simple. You will start by replacing one of your dirt bike’s stock cogs. For example, you may change the bike’s stock 14 tooth drive cog to a 15-tooth sprocket to achieve the top speed.

Similarly, swapping your bike’s stock 42 tooth rear sprocket gearing with a 32-tooth sprocket gearing will add the speed but affect the low-end torque acceleration. In other words, understanding how the sprocket gearing works gives you an idea of increasing your bike’s average speed without really cooperating torque acceleration. The torque acceleration is essential to help your bike gain top speeds in minutes or seconds. Modifications can advance the speed of your dirt bike by a large margin and set you ahead of other riders.

7. Terrain

The kind of terrain that you are riding on will disturb your bike’s speed. Hard exteriors like roadways will permit you to reach higher speeds than soft surfaces like sand or mud.
