Honda Grom Top Speed

The Honda Grom is a popular mini motorcycle that is known for its fun and playful nature. One of the most common questions asked about the Grom is its top speed. In this section, we will explore the stock and modified top speeds of the Honda Grom.

Stock Honda Grom Top Speed

The stock Honda Grom has a top speed of around 55-73 MPH, depending on the rider’s weight and the road conditions. The Grom’s small 125cc engine produces around 9 horsepower and 8 lb-ft of torque, which is enough to propel the bike to its top speed.

The Grom’s top speed is not particularly fast, but it is more than enough for city riding and having fun on twisty back roads. The Grom is not designed for highway riding, so riders should avoid taking it on highways or other high-speed roads.

Modified Honda Grom Top Speed

Many Grom owners modify their bikes to increase their top speed and overall performance. Some popular modifications include upgrading the exhaust system, installing a new air intake, and adding a fuel controller.

With these modifications, the Honda Grom can reach top speeds of up to 80-90 MPH. However, it is important to note that modifying the Grom can void its warranty and may not be legal in some states.

In addition to modifying the engine, riders can also improve the Grom’s top speed by upgrading the suspension and brakes. These upgrades can help the bike handle better at higher speeds and make it safer to ride.

Factors Affecting Honda Grom Top Speed

When it comes to the Honda Grom’s top speed, there are several factors that can affect it. These factors include the rider’s weight, rider position, and wind conditions.

1. Weight

The weight of the rider is one of the most significant factors that can affect the top speed of the Honda Grom. Heavier riders will experience more wind resistance, which can slow down the bike. On the other hand, lighter riders will experience less wind resistance, which can allow the bike to go faster.

2. Rider Position

The position of the rider on the Honda Grom can also affect the bike’s top speed. Riders who are in a more aerodynamic position, with their body positioned closer to the tank, will experience less wind resistance and may be able to achieve a higher top speed. Additionally, riders who are more experienced and comfortable on the bike may be able to achieve a higher top speed due to their ability to control the bike more effectively.

3. Wind Conditions

Wind conditions can also play a significant role in the Honda Grom’s top speed. Strong headwinds can slow down the bike, while tailwinds can help the bike go faster. Crosswinds can also affect the bike’s stability, which can impact the rider’s ability to control the bike and maintain a high speed.

How to Increase Honda Grom Top Speed?

If you’re looking to increase the top speed of your Honda Grom, there are several modifications you can make to achieve your goal. Here are some ways to increase your Honda Grom’s top speed:

Upgrading the Exhaust System

Upgrading the exhaust system is one of the most popular ways to increase the top speed of your Honda Grom. A good aftermarket exhaust system can increase horsepower and torque, which can lead to a higher top speed. The Yoshimura exhaust system is a popular choice among Honda Grom enthusiasts and claims a 13.9% increase to peak horsepower and 14.3% increase to peak torque when compared to the stock exhaust.

Modifying the Air Intake System

Modifying the air intake system can also help increase the top speed of your Honda Grom. A high-performance air filter and intake system can increase airflow to the engine, which can improve acceleration and top speed. TST Industries offers a high-performance air filter and intake system specifically designed for the Honda Grom.

Upgrading the Fuel System

Upgrading the fuel system can also help increase the top speed of your Honda Grom. A high-performance fuel injector or fuel pump can increase fuel flow to the engine, which can lead to improved performance and higher top speed. However, upgrading the fuel system can be expensive and may require professional installation.

Tuning the Engine

Tuning the engine can also help increase the top speed of your Honda Grom. A good engine tune can optimize the air/fuel mixture and ignition timing, which can lead to improved performance and higher top speed. However, engine tuning can be complex and should be done by a professional.

Reducing Weight

Reducing weight is another way to increase the top speed of your Honda Grom. Removing unnecessary parts or replacing heavy parts with lighter ones can improve acceleration and top speed. However, it’s important to keep in mind that removing certain parts can affect the handling and safety of your Honda Grom.

Safety Considerations

When riding any motorcycle, including the Honda Grom, safety should always be a top priority. Here are some safety considerations to keep in mind when riding the Honda Grom:
