SlashGear’s June 2, 2026 ranking puts 12 motorcycles in order of reported fuel economy, but its figures are not results from one standardized test. The article combines rider reviews, reported fill-ups and mileage tracking, and manufacturer MPG figures, so treat the order as a useful comparison—not a guarantee of what you will get on the road.
How to read the ranking
SlashGear’s ranking, by Joseph Pallante and updated June 2, 2026, orders its entries from higher to lower MPG. Its stated method draws on rider reviews, fill-up frequency and total mileage tracked, along with manufacturers’ reported MPG. Those sources do not establish a like-for-like comparison across all 12 motorcycles, and the list spans different markets, model years, and motorcycle categories.
That distinction matters: an owner’s observed fuel economy, a manufacturer estimate, and a publication’s testing experience are different kinds of evidence. Motorcyclist’s February 5, 2025 overview also describes a mix of reader testimony, manufacturer claims, and its own testing experiences. It provides context for how such lists are assembled, but does not independently validate every figure in SlashGear’s ranking.
The ranking’s title promises 12 entries, but the available figures here do not include the individual model names, model years, or MPG values. Without those details, reproducing a numbered list would risk inventing or misattributing values. The comparisons below instead show what verified, clearly attributed figures can tell you—and where they cannot be directly compared.

Fuel-economy figures with clear attribution
| Source and scope | Published figure | What it represents |
|---|---|---|
| Honda Powersports, 2026 Honda Monkey | 162.6 MPG | Honda’s estimate for the 2026 model, intended for comparison; not a guaranteed real-world result. |
| MotoIndex PH, Philippine-market comparison checked October 4, 2026 | 69.5 km/L | The highest published figure in MotoIndex PH’s qualifying set, attributed to the Honda Wave RSX; a database comparison, not a controlled test. |
Honda’s 2026 Monkey specifications explain that the MPG estimate uses EPA exhaust-emission measurement test procedures and is intended to compare vehicles. Honda cautions: “Your actual mileage will vary depending on how you ride, how you maintain your vehicle, weather, road conditions, tire pressure, installation of accessories, cargo, rider weight, and other factors.” The estimate is specific to the 2026 Monkey; it should not be substituted for a figure attached to another model year or another motorcycle.
MotoIndex PH’s comparison covers 65 motorcycles and describes its figures as manufacturer-published or otherwise sourced consumption values. It warns that differing test conditions make them references rather than perfectly comparable real-world results. Its Honda Wave RSX figure is in km/L and belongs to a Philippine-market dataset—not an extension of a U.S. ranking. Converting units would not remove differences in market, model specification, or measurement basis.

Why the most efficient bike may not be the best choice
Fuel economy is only one part of choosing a motorcycle. A small, economical bike may suit short urban trips but not your preferred pace or longer routes. Consider the motorcycle’s intended use, engine and transmission, rider fit, safety equipment, tank capacity, local price, and availability alongside its fuel-consumption figure.
- Match the use: Check whether the bike’s category, engine, and transmission suit commuting, city errands, or longer journeys.
- Check fit and equipment: Seat height, weight, braking equipment, and any ABS configuration may matter more to your daily comfort and needs than a small MPG difference.
- Separate economy from range: A larger tank can extend distance between stops without improving fuel efficiency. Range calculations based on fuel economy and tank capacity are theoretical, not a promise of usable distance.
- Confirm local ownership details: Prices and availability vary by market and date. A price quoted in pesos for a Philippine model should not be treated as a global price.
How to compare two motorcycles fairly
- Identify the exact version. Record the model year, market, and configuration; similarly named motorcycles can differ across countries and years.
- Label the evidence. Note whether each MPG or km/L figure is a manufacturer estimate, a publication test, or owner-reported tracking. Do not treat them as equivalent measurements.
- Compare the intended role. Make sure both motorcycles meet your needs for route, engine, transmission, passenger or cargo use, and rider fit.
- Estimate range cautiously. If you use a published economy figure and tank capacity to estimate range, regard the result as theoretical and allow for real-world variation.
- Check the local deal. Verify current availability, price, specifications, and safety equipment with a local seller or the manufacturer for the exact model year.
There is no sound basis in these model-level figures for claiming a typical motorcycle MPG, average fuel savings, or annual cost reduction for riders generally. Those outcomes depend on the motorcycle, rider, route, and how fuel use is measured.
