How fast does a honda grom go?

By HotBotUpdated: September 30, 2024

The Honda Grom has quickly become a beloved motorcycle for both beginners and experienced riders. Known for its compact size, nimble handling, and fun ride, one of the most frequently asked questions about the Honda Grom is, "How fast does it go?" In this article, we will dive deep into the speed capabilities of the Honda Grom, exploring various factors that influence its performance.

Top Speed of a Stock Honda Grom

In its stock form, the Honda Grom typically reaches a top speed between 55 to 60 mph. This range can vary slightly based on a number of factors such as rider weight, riding conditions, and maintenance of the bike. The Grom is powered by a 125cc single-cylinder engine, which is designed more for urban commuting and fun than for high-speed performance. Despite its modest top speed, the Grom delivers a thrilling riding experience thanks to its lightweight frame and responsive handling.

Factors Affecting Speed

Rider Weight

One significant factor that affects the top speed of a Honda Grom is the weight of the rider. Heavier riders may find that their Grom struggles to reach the higher end of its top speed range, while lighter riders may more easily achieve speeds closer to 60 mph. The weight of any additional gear or cargo can also play a role.

Riding Conditions

Environmental factors such as wind, terrain, and road conditions can also impact the Grom's speed. Riding uphill or against a strong wind can reduce the bike's top speed, while favorable conditions like a smooth, flat road with a tailwind can help the Grom reach its maximum speed more easily.

Maintenance and Modifications

Proper maintenance is crucial for ensuring that the Grom performs at its best. Regular oil changes, tire maintenance, and other routine checks can help keep the bike running smoothly. Additionally, some riders choose to modify their Grom to enhance its performance. Common modifications include upgrading the exhaust system, installing a performance air filter, or even adjusting the bike's gearing to achieve a higher top speed.

Modifications to Increase Speed

For those looking to push their Honda Grom beyond its stock performance, there are several modifications that can be made. However, it's important to note that these modifications can affect the bike's warranty and may not be legal in all areas. Here are some popular upgrades:

Exhaust System

Upgrading the exhaust system is a common modification among Grom enthusiasts. An aftermarket exhaust can reduce weight and increase the bike's power output, potentially adding a few extra miles per hour to the top speed. Popular brands for Grom exhausts include Yoshimura, Two Brothers Racing, and Akrapovic.

Air Intake and Fuel Management

Improving the bike's air intake and fuel management can also enhance its performance. Installing a high-performance air filter can allow the engine to breathe more easily, while a fuel management system can optimize the air-fuel mixture for better power delivery. Combining these upgrades with a performance exhaust can yield noticeable gains in speed and acceleration.

Gearing Changes

Adjusting the Grom's gearing is another way to increase its top speed. By changing the size of the front and rear sprockets, riders can alter the bike's power delivery to favor higher speeds. For example, installing a smaller rear sprocket or a larger front sprocket can result in a higher top speed, although this may come at the expense of acceleration and low-end torque.

Comparisons with Other Small Motorcycles

When considering the Honda Grom's speed, it's helpful to compare it to other small motorcycles in its class. Here are a few popular models and their top speeds:

Kawasaki Z125 Pro

The Kawasaki Z125 Pro is a direct competitor to the Honda Grom. With a similar 125cc engine, the Z125 Pro boasts a top speed of around 60 mph, making it a close match to the Grom in terms of speed and performance.

Benelli TNT 135

The Benelli TNT 135 is another small-displacement motorcycle that has gained popularity. Featuring a slightly larger 135cc engine, the TNT 135 can achieve a top speed of approximately 65 mph, giving it a slight edge over the Grom and Z125 Pro in terms of speed.

KTM 125 Duke

The KTM 125 Duke is a more performance-oriented option in the small motorcycle category. With a 125cc engine that produces more power than the Grom, the 125 Duke can reach speeds of up to 70 mph. However, it is also typically more expensive and may not offer the same level of accessibility and ease of use as the Grom.

Real-World Riding Impressions

While top speed is an important metric, real-world riding impressions provide valuable insights into the Honda Grom's overall performance and enjoyment. Riders often praise the Grom for its agility, ease of maneuverability, and the sheer fun factor it offers. Despite its modest top speed, the Grom's quick acceleration and responsive handling make it a joy to ride in urban environments and on twisty roads.

Many riders find that the Grom's top speed is more than sufficient for city commuting and casual weekend rides. Its compact size allows it to easily navigate through traffic, and its light weight makes it easy to park and handle. The Grom's approachable nature and playful character contribute to its widespread appeal, making it a popular choice for new riders as well as experienced motorcyclists looking for a fun secondary bike.

Unique Aspects of the Honda Grom

The Honda Grom isn't just about speed; its unique characteristics set it apart from other motorcycles. One of the standout features of the Grom is its customization potential. Many owners enjoy personalizing their Groms with custom paint jobs, unique graphics, and a wide range of aftermarket parts. This customization culture has led to a vibrant community of Grom enthusiasts who share their modifications and experiences online.

Additionally, the Grom's fuel efficiency is a significant advantage. With an estimated fuel economy of around 134 mpg, the Grom is incredibly cost-effective to operate. This makes it an appealing option for budget-conscious riders and those looking to minimize their environmental impact.

Embracing the Grom's Speed and Beyond

While the Honda Grom's top speed may not be its most impressive attribute, it's clear that this little bike offers much more than just speed. Its combination of agility, customization options, fuel efficiency, and sheer fun factor make it a standout choice in the world of small motorcycles. Whether you're zipping through city streets or exploring winding backroads, the Honda Grom delivers an experience that goes beyond the numbers on the speedometer.
