How to Make a Honda C90 Go Faster: A Step-by-Step Guide

Are you looking to give your Honda C90 a speed boost? The Honda C90, also known as the Super Cub, is a popular motorcycle known for its reliability and fuel efficiency. While it may not be the fastest bike on the road, there are several modifications you can make to increase its speed and performance.

1. Upgrade the Exhaust System

The exhaust system plays a crucial role in improving the performance of your Honda C90. By upgrading to a high-performance exhaust system, you can increase horsepower and torque, resulting in a faster and more responsive ride. A free-flowing exhaust system allows the engine to expel exhaust gases more efficiently, leading to improved performance.

Here’s a YouTube video that demonstrates how to make your standard Honda C90 go faster by upgrading the exhaust system:

2. Install a High-Flow Air Filter

A high-flow air filter can significantly improve the airflow to the engine, resulting in increased power and better fuel combustion. By replacing the stock air filter with a high-flow variant, you can enhance the overall performance of your Honda C90. This simple modification can make a noticeable difference in the bike’s acceleration and top speed.

3. Optimize the Carburetor

The carburetor plays a crucial role in regulating the fuel-air mixture in the engine. By properly tuning and adjusting the carburetor, you can optimize the fuel delivery and air intake, leading to improved performance. It is recommended to consult a professional or refer to the manufacturer’s manual for precise carburetor tuning instructions.

4. Upgrade the Ignition System

Upgrading the ignition system can result in improved combustion efficiency, leading to better power delivery and increased speed. Consider installing a high-performance ignition coil, spark plug, and CDI unit to enhance the overall ignition process. These upgrades can make a significant difference in the bike’s performance, especially during acceleration.

5. Reduce Weight

One of the simplest ways to improve the speed of your Honda C90 is by reducing its weight. Remove any unnecessary accessories or components that add extra weight to the bike. Additionally, consider replacing heavy stock parts such as the exhaust pipe with lighter aftermarket alternatives. By shedding a few pounds, you can enhance the bike’s power-to-weight ratio, resulting in improved acceleration and top speed.

6. Upgrade the Sprockets

Another effective way to increase the speed of your Honda C90 is by upgrading the sprockets. By changing the sprocket ratio, you can either increase the top speed or improve acceleration. A larger rear sprocket or a smaller front sprocket will provide more torque and better acceleration, while a smaller rear sprocket or a larger front sprocket will result in a higher top speed.

7. Perform Regular Maintenance

Regular maintenance is essential to keep your Honda C90 in optimal condition. Ensure that you change the engine oil, clean or replace the air filter, and inspect the spark plug regularly. A well-maintained bike will perform better and have a longer lifespan. Regular maintenance also allows you to identify any potential issues that may be affecting the bike’s performance.

8. Upgrade the Suspension

While upgrading the suspension may not directly increase the speed of your Honda C90, it can significantly improve the bike’s handling and stability. By installing high-quality suspension components, you can enjoy a smoother ride and better control, especially when riding at higher speeds.

9. Consider Engine Modifications

If you’re looking for more significant performance improvements, you may consider engine modifications such as a big bore kit, high-compression piston, or a performance camshaft. These modifications require advanced technical knowledge and are typically performed by experienced mechanics. It is important to note that engine modifications may also impact the bike’s reliability and fuel efficiency.

10. Practice Safe Riding Habits

While these modifications can enhance the speed and performance of your Honda C90, it is essential to prioritize safety. Always follow traffic rules, wear appropriate safety gear, and ride responsibly. Speeding can be dangerous, especially on a smaller bike like the Honda C90. Practice safe riding habits to ensure your own safety and the safety of others on the road.

Conclusion

By following these steps and making the necessary modifications, you can make your Honda C90 go faster and enjoy a more thrilling riding experience. Remember to prioritize safety and consult professionals or refer to the manufacturer’s guidelines whenever necessary. With the right modifications and regular maintenance, you can unlock the full potential of your Honda C90.
