How Fast Do Honda Groms Go
The Honda Grom, also known as the MSX125, is a small but mighty bike. Despite its compact size, it packs a punch when it comes to speed and performance. Let’s break it down.
The maximum speed of a Honda Grom can vary depending on the model and conditions:
| Model Year | Top Speed (mph) |
| 2020 Honda Grom | 58.4 mph |
| 2022 Honda Grom | 59 mph |
| 2023 Honda Grom | 72 mph (reported by riders) |
Performance and Power ⚙️
The Honda Grom is equipped with a 125cc air-cooled engine, producing around 9.7 horsepower. This might seem small, but for a bike its size, it’s quite zippy.
Real-world Speed 🏁
We’ve observed that the actual top speeds often depend on factors like:
- Rider Weight 💨
- Terrain 🌡️
- Modifications 🛠️
On average, most of the models hover around 55-60 mph in real-world conditions, but some riders managed to hit up to 72 mph. That’s pretty impressive for this pocket rocket!
Speed Performance in City Rides 🚗
With its efficient engine and nimble design, the Grom is perfect for city rides. It moves effortlessly through traffic and is quite fuel-efficient too, making it a favorite among commuters.
The recent generations, such as the 2022 and 2023 models, have introduced improvements in transmission and design, contributing to slightly better speeds and overall riding experience.
Owning a Grom feels like having a spirited companion that’s always up for an adventure, making every ride exciting, yet practical.
Factors Affecting Honda Grom Speed
When it comes to how fast a Honda Grom can go, several key factors come into play. These factors range from the engine specifications and aerodynamics to the weight considerations of both the bike and rider.
Engine Specifications
The Honda Grom’s speed is heavily influenced by its 125cc air-cooled single-cylinder engine. This compact motor may seem small, but it packs a punch to deliver around 9.7 horsepower. The engine features fuel injection which ensures smooth and efficient power delivery.
Key technical specs include a bore x stroke of 52.4 mm x 57.9 mm, contributing to its efficient operation. The five-speed transmission allows for a flexible riding experience, enabling the rider to manage different speeds effectively.
Torque is another crucial aspect; the Grom generates 10.5 Nm at 5,500 RPM, helping it climb hills and navigate diverse terrains. Engine temperature, though generally stable, can also affect performance, especially in extreme weather conditions.
Aerodynamics
Despite its compact design, the aerodynamics of the Grom can significantly impact its speed. The bike’s shape and the rider’s posture create wind resistance that must be overcome to achieve top speeds. This is more evident at higher speeds where air resistance increases.
Riding uphill or downhill also affects the bike’s aerodynamics. Going downhill, the Grom can utilize gravity to reduce wind resistance and increase speed, while uphill rides create more drag, slowing the bike down.
Additionally, the absence of a full fairing means the rider experiences more wind drag. Modifications like windscreens can help reduce this, allowing for better aerodynamics.
Weight Considerations
Weight plays a vital role in determining the Honda Grom’s speed. The bike itself is relatively lightweight, weighing about 227 lbs. This enhances its nimble handling and maneuverability. However, the weight of the rider and any additional gear can influence overall performance.
Carrying a passenger or exceeding the weight limit can strain the engine, reducing speed and fuel efficiency. Terrain also matters—on flat surfaces, the Grom performs better compared to hilly or uneven ground.
In conclusion, understanding these factors helps us appreciate the Honda Grom’s capabilities and limitations. Whether you’re cruising on city streets or exploring winding roads, these elements collectively shape your riding experience. Ride smart and enjoy the journey!
Comparing Honda Grom Speed To Other Models
Honda Groms are popular for their agility and fun riding experience, but they also face tough competition. Here, we’ll compare the speed of the Honda Grom to the Honda Monkey and the Kawasaki Z125.
Honda Grom Vs. Honda Monkey
The Honda Monkey is quite similar to the Grom in many ways. Both bikes have a 125cc engine.
The Grom reaches up to 58.4 mph, while the Monkey tops out around 55 mph. This is a small but noticeable difference, especially for city riders who enjoy speedy commutes.
In terms of design, the Monkey has a retro look that appeals to many riders. It’s more of a nostalgic choice for those who love classic bikes. The Grom, on the other hand, has a modern, almost futuristic design.
When we look at maneuverability, both bikes perform well in tight city spaces and narrow streets. They’re easy to park and offer excellent fuel efficiency.
Honda Grom Vs. Kawasaki Z125
The Kawasaki Z125 is another competitive model in the mini-bike category. It has a 125cc engine, identical to the Grom’s.
Grom reaches 58.4 mph, while the Z125 can hit about 60 mph. The Z125 slightly edges out the Grom in top speed, making it a good choice for those looking for a bit more power.
When comparing pricing, the Z125 often comes in at a lower price point, which makes it an appealing choice for budget-conscious riders.
Both bikes offer excellent handling, but the Z125’s sportier design offers a different feel compared to the Grom. The Grom’s upright riding position is more comfortable for longer rides.
Enhancing The Speed Of Your Honda Grom
If you’re looking to soup up your Honda Grom, there are several ways to go about it. We’ll discuss the use of aftermarket parts and the importance of tuning and maintenance.
Aftermarket Parts
To boost your Grom’s speed, you can start with the exhaust system and air intake system. Upgrading these parts helps the engine breathe better and push out more power. A high-flow air filter can improve airflow, while a performance exhaust reduces backpressure.
Changing the rear sprocket can also increase your top speed. Opt for a sprocket with fewer teeth if you want to go faster. Just remember, this will affect your bike’s acceleration.
Larger wheels and tires can offer better grip and stability, making your ride smoother and faster. Be sure to check the fuel tank and fuel capacity; a larger fuel tank means fewer stops on long rides. Lastly, don’t forget about the chain and swingarm. A high-quality chain will reduce resistance and wear, offering better performance.
Tuning and Maintenance
Regular tuning is key. Without it, even the best parts won’t perform well. Adjusting the fuel mixture and ignition timing can help your engine run more efficiently. You may need to use a fuel tuner or ECU flash to maximize these settings.
Keep an eye on the tires. Worn-out tires can slow you down and make your ride less safe. Make sure to keep them properly inflated.
Don’t overlook the small stuff! Regular oil changes, clean air filters, and checks on the cooling system can make a big difference.
Lastly, customizing your Grom for less weight can make it faster. Remove any unnecessary parts and replace heavy ones with lighter alternatives. This could be your side panels or even your fuel tank.
