The Honda Grom is a popular mini-bike with a 125cc engine that has been gaining popularity in recent years. It’s small and nimble, making it an enjoyable ride for city and suburban roads.

However, many people wonder if the Honda Grom can go on the highway, where speeds are higher and traffic can be more intense.

The Honda Grom’s Engine

One of the main concerns people have when it comes to taking the Honda Grom on the highway is its engine size. With only 125cc, many believe that the Grom would not have enough power to handle highway speeds. However, it is important to note that the Grom’s engine is specifically designed for city and suburban riding, where speeds rarely exceed 40 mph.

  • The Honda Grom’s engine is air-cooled.
  • It has a single-cylinder four-stroke engine.
  • The engine produces around 9 horsepower and 8 lb-ft of torque.
  • Its top speed is around 55 mph.

While the Grom’s engine is not built for high-speed cruising, it is powerful enough to handle short bursts of highway speeds.

However, it is recommended that riders do not push the Grom above 60 mph, as it can become unstable and difficult to control.

The Grom’s Size and Weight

Another factor to consider when it comes to taking the Honda Grom on the highway is its size and weight. The Grom is incredibly compact, making it easy to maneuver through city streets and tight spaces.

However, on the highway, the Grom’s small size and weight can make it vulnerable to strong winds and other external factors.

  • The Honda Grom has a seat height of 30 inches.
  • It weighs around 225 pounds.
  • The Grom’s wheelbase is only 47.2 inches.
  • It has 12-inch wheels with a relatively narrow tire base.

While the Grom’s size and weight make it highly maneuverable in tight spaces, it can also make it difficult to maintain control at higher speeds on the highway.

The lightweight nature of the Grom can make it feel unstable and wobbly in windy conditions. Riders must be cautious and vigilant when taking the Grom on the highway and should avoid areas with high winds.

A common question that arises when considering taking the Honda Grom on the highway is whether it is legal.

Depending on where you live, the laws regarding mini-bikes and highway riding may vary. In general, however, the Honda Grom is not legal for highway riding in most parts of the United States.

In many states, mini-bikes must meet specific requirements to be allowed on the highway. These requirements often include things like minimum engine size, turn signals, and headlights.

The Grom does not meet most of these requirements, making it illegal to ride on the highway.

Tips for Taking the Honda Grom on the Highway

While it is not recommended that riders take the Honda Grom on the highway, there may be some situations where it is necessary. Here are some tips for those who must take the Grom on the highway:

  • Only ride on highways with low traffic volumes and speeds under 50 mph.
  • Be aware of your surroundings and be prepared for sudden gusts of wind or changes in traffic flow.
  • Wear protective gear, including a helmet, gloves, and sturdy boots.
  • Avoid highways with steep inclines or bridges, as the Grom may struggle with these obstacles.
  • Stay in the right-hand lane and avoid changing lanes frequently.
  • Keep a close eye on the Grom’s temperature gauge to avoid overheating.
  • Be aware of the Grom’s fuel range, as it has a small fuel tank and may not be able to travel long distances without refueling.


In conclusion, while the Honda Grom is a fun and nimble bike for city and suburban riding, it is not recommended for highway use.

The Grom’s small engine size and lightweight construction make it difficult to handle at high speeds, and its lack of specific highway equipment makes it illegal in most areas for highway use.

Riders who must take the Grom on the highway should exercise caution and follow the tips mentioned above to ensure a safe and enjoyable ride.
