Gas mileage isn’t just a number on paper, it’s a story of how far you can go without emptying your wallet. And when it comes to efficiency, few motorcycles spark the same kind of buzz as the Honda Grom. This pint-sized street bike may look like a toy, but its fuel economy is anything but child’s play.
So, just how many miles can you squeeze out of a gallon on a Grom? Let’s dive into the story of this efficient little beast, why it’s become a cult favorite, and what real riders can expect when it comes to Honda Grom gas mileage.
The Rise of the Honda Grom
When Honda introduced the Grom in 2014, it disrupted the motorcycle scene in the best way. Riders were used to large, powerful machines, but here came a 125cc mini-bike with style, spunk, and an unexpected level of practicality.
It wasn’t long before the Grom found its place with city commuters, beginner riders, and even veteran bikers who wanted something light, agile, and fun. And that’s where gas mileage became a huge talking point.
How Fuel Efficient Is the Honda Grom?
Here’s the headline you’ve been waiting for:
The Honda Grom gets up to 134 MPG, yes, you read that right.
Depending on the year and riding habits, some owners report even higher numbers, while others average closer to 100–110 MPG. Still, that makes the Grom one of the most fuel-efficient motorcycles on the market.
Let’s break it down:
- Fuel Capacity: 1.6 gallons
- Range per Tank: Up to 214 miles on a full tank
- Fuel Type: Regular unleaded
For comparison, a typical car might get 25–30 MPG, while larger motorcycles often range between 40–60 MPG. The Grom simply dominates the fuel economy game.
What Grom Riders Say
Numbers are one thing, but the riding experience tells the real story. Across forums, YouTube reviews, and motorcycle blogs, riders rave about how far they can travel on just a few bucks.
“I ride my Grom to work every day. I fill up once every two weeks, and it costs me under five bucks,” says a rider from Denver, CO.
Another from San Diego adds,
“Even riding it hard, I still get over 100 MPG. It’s the best investment I’ve made.”
Of course, riding style and terrain affect mileage. Aggressive throttle use, constant high-speed riding, or hilly routes can drop your MPG slightly. But even then, the Grom holds strong against much larger bikes.
Why the Grom Is the Ultimate Commuter Bike
If you’re searching for the best used commuter car but you’re open to two wheels, the Grom offers an alternative that’s not only affordable to buy but incredibly cheap to operate.
Here’s why it’s commuter gold:
- Compact and easy to park in any urban setting
- Low insurance premiums due to its small engine
- Minimal maintenance costs, it’s a Honda, after all
- Excellent resale value, thanks to its cult following
When you pair the Grom’s gas mileage with its overall running costs, it becomes clear why many urban dwellers are choosing two wheels over four.
How the Honda Grom Compares to Similar Bikes
Let’s see how the Grom stacks up against a few competitors in the mini-bike and beginner motorcycle category:
| Bike Model | Engine | MPG (est.) |
| Honda Grom | 125cc | 134 |
| Kawasaki Z125 Pro | 125cc | 103 |
| Yamaha MT-03 | 321cc | 56 |
| Honda Monkey | 125cc | 134 |
| KTM Duke 200 | 199cc | 88 |
As you can see, the Grom and its cousin, the Monkey, dominate this space. They deliver unmatched efficiency without sacrificing ride quality or street-legal capability.
Maximize Your Honda Grom’s Gas Mileage
While the Grom already sips fuel like a champion, here are a few tips to stretch your tank even further:
- Keep your tires properly inflated: Low pressure increases drag and reduces efficiency.
- Use high-quality motor oil: Clean oil minimizes engine resistance.
- Avoid excessive idling: Turn off the bike when waiting for extended periods.
- Accelerate smoothly: Quick throttle blasts lower your MPG.
- Regular maintenance: Clean the air filter and spark plug regularly to keep the engine in top shape.

Ownership Costs Beyond Gas
Fuel economy is just one part of the cost equation. Luckily, the Grom is also incredibly affordable in other areas:
- MSRP (New): Around $3,599 (2025 model)
- Insurance: Typically under $200 per year for most riders
- Maintenance: Simple oil changes and basic service, often DIY-friendly
- Parts Availability: Widely available and cheap
Compare that with a standard vehicle, and you’ll save thousands, not just at the pump but throughout your entire ownership experience.

- Gas mileage that rivals electric scooters
- Fun factor that surprises even seasoned bikers
- Cost of ownership that beats nearly every alternative
Sure, it’s not built for highway cruising or long-distance two-up rides, but if you’re looking to zip around the city or enjoy a quick spin with max efficiency, the Honda Grom checks all the boxes.
