The Honda Grom is a popular mini-motorcycle known for its fun handling and fuel economy. The top speed of a stock Honda Grom is around 60 miles per hour. However, there are a few things you can do to increase the Grom’s top speed, such as changing the gearing, adding a performance exhaust, or installing a big bore kit.
Gearing
One of the easiest ways to increase the Grom’s top speed is to change the gearing. This involves replacing the front or rear sprocket with a larger or smaller one.
A larger rear sprocket will make the Grom accelerate faster, but it will also reduce its top speed. A smaller rear sprocket will increase the honda grom top speed, but it will also reduce its acceleration.
The best gearing for the Grom will depend on your riding style and needs. If you mostly ride in urban areas, you may want to choose a larger rear sprocket to make the Grom more fun and agile. If you do a lot of highway riding, you may want to choose a smaller rear sprocket to increase the Grom’s top speed.
Performance Exhaust
Another way to increase the Grom’s top speed is to add a performance exhaust. A performance exhaust will allow the Grom’s engine to breathe more efficiently, which can lead to increased power and torque.
There are a variety of performance exhaust systems available for the Grom, so you can choose one that fits your budget and needs.
Big Bore Kit
The most significant way to increase the Grom’s top speed is to install a big bore kit. A big bore kit increases the displacement of the Grom’s engine, which can lead to significant gains in power and torque.
Big bore kits are available in a variety of sizes, so you can choose one that is right for your vehicle. However, it is important to note that installing a big bore kit will void the Grom’s warranty and may require other modifications, such as a new fuel controller.
Other Factors that Affect Top Speed
In addition to gearing, exhaust, and engine displacement, there are a few other factors that can affect the Grom’s top speed, such as:
- Rider weight: A heavier rider will slow the Grom down.
- Wind resistance: The Grom is a small motorcycle, so it is very susceptible to wind resistance. Riding with a tuck or behind a windshield can reduce wind resistance and increase top speed.
- Incline: The Grom will be slower uphill and faster downhill.
Safely Increasing Top Speed
It is important to note that increasing the Grom’s top speed can make it more dangerous to ride. It is important to be aware of your surroundings and ride within your limits.
If you do decide to increase the Grom’s top speed, it is important to make sure that the bike is properly maintained and that you are wearing all of the necessary safety gear.
Conclusion
The Honda Grom is a fun and affordable motorcycle that is perfect for beginners and experienced riders alike. While the Grom’s top speed is not impressive, it can be increased with a few modifications.
If you are considering modifying your Grom to increase its top speed, it is important to weigh the risks and benefits. It is also important to make sure that the bike is properly maintained and that you are wearing all of the necessary safety gear.
