How to Increase Speed in a 50cc Dirt bike

A 50cc dirt bike is quite a first bike, though not as most people would want it to be. It's light enough to be easy to control, yet powerful enough to provide some thrilling rides.

So, it is possible to increase the speed of your dirt bike 50cc, but it will take some work. You can do this yourself, but if you're not familiar with mechanics and electronics, you may want to find a professional who can help.

Steps to Increase the Speed of Your Dirt Bike

Step 1: Replace the Carburettor

If your carburettor is worn out, it can cause your engine to lose power and run poorly. The carburettor has several parts that regulate the fuel mixture as it enters the engine. Parts like jets and floats all need to be replaced or cleaned regularly for optimal performance. This can be done by a mechanic or by yourself if you have experience with small engines.

Step 2: Change Your Spark Plug

A spark plug supplies electricity to ignite fuel in an engine so it can start running. If your spark plug is worn out or dirty, it won't work properly and cause problems when starting up your machine — leading to low acceleration and poor performance overall. Replacing a spark plug should be done at least once per year for optimal performance from your engine. The process for changing spark plugs varies depending on what type of vehicle you have.

Step 3: Replace the Aftermarket Cylinder

If you're looking for more horsepower, you should consider installing an aftermarket cylinder head. This will give your dirt bike better compression and allow it run at higher RPMs without stalling out or losing power due to an overly lean fuel mixture ratio (too much fuel).

Step 4: Upgrade the Tires

Upgrade your tires. Having better tires on your bike will allow you to go faster without having any issues with traction or stability. You should also get new rims for your wheels and make sure that they are not worn out or damaged in any way as this could cause them to fail while riding at high speeds.

Step 5: Change Your Gearing System

If you have a standard bike with three or four gears, then you will probably want to change this to an automatic transmission or dual-clutch system. You can also change your gearing system by adding more gears to each stage of transmission, which will allow you to shift more smoothly and quickly between them.

Step 6: High Performance Exhaust System

A high-performance exhaust system improves the flow of air into and out of the engine, which increases horsepower. The size of the pipe determines how much power is produced by an engine and determines how fast it will go. Larger pipes are more expensive than smaller ones, but they will make your bike go faster.


Increasing the speed in a 50cc dirt bike can be done. It all depends on how it is done and why you are doing it. As an owner of a 50cc dirt bike, you need to know that you limit it to only going up to 30-35 miles per hour because of the lower size wheels that come as standard with a 50cc dirt bike. Any faster and you will increase your chances of having an accident.
