For sport bikes, Suzuki GSX250R and Honda CBR500R lead with ~70–74 mpg US; 125–155cc faired models claim 50–60 km/l in test cycles.
If you typed “which sport bike has highest mileage?” you’re likely weighing speed against stops at the pump. This guide gets straight to the point with verified numbers, simple comparisons, and clear picks. You’ll see where the best mpg shows up, why small twins shine, and when lab claims differ from day-to-day riding.
Which Sport Bike Has Highest Mileage? Real-World Answer
In current dealer showrooms, two fully-faired models consistently sit at the top of the real-world pile: Suzuki’s GSX250R and Honda’s CBR500R. Suzuki lists an estimated 73.6 mpg US for the GSX250R on its product page, and Honda lists 72 mpg US for the CBR500R using its standard comparison procedure (your results will vary). For many riders, that’s the sweet spot: proper sport ergonomics, usable power, and fuel numbers that beat most midsize and big-bore machines. Sources: GSX250R specifications and CBR500R specifications.
Small-displacement sport bikes also return standout numbers under test cycles. In markets that use ARAI or WMTC lab procedures, 125–155 cc faired bikes often claim 50–60 km/l (that’s 118–141 mpg US) in ideal conditions. Real owners usually report lower but still strong results, especially with smooth throttle and light loads.
Sport Bike With The Highest Mileage: Leaders By Class
Below is a quick, scan-friendly table of fuel economy standouts you can actually buy or find used easily. It mixes official estimates and large-sample owner averages where manufacturers don’t publish mpg. Figures are rounded for readability; real-world mileage depends on pace, weight, wind, altitude, and maintenance.

| Suzuki GSX250R (owners) | 248 cc twin | ~74 mpg US average (owner logs) |
How We Picked The Mileage Winners
We started with official specs where brands publish mpg or consumption. Honda publishes a 72-mpg figure for the CBR500R, and Suzuki publishes 73.6-mpg for the GSX250R. Yamaha lists 56-mpg for the YZF-R3. When brands don’t list mpg, we used large owner databases to cross-check. The Ninja 400, for instance, sits around the mid-50s mpg US across many fuel-ups. For small 125–155 cc faired bikes, we looked at ARAI and WMTC claims, then compared them with rider-reported averages to set realistic expectations.
Why 250–500 Cc Twins Win On Range
They carry taller gearing, cruise at lower rpm, and hold speed with less throttle. That makes steady-state highway numbers strong without sacrificing overtakes. The CBR500R is a textbook example: a calm, understressed twin that sips fuel when cruising, yet still quick enough to run with traffic.
Where 125–155 Cc Sport Bikes Shine
Around town. Light frames, narrow tires, and low pumping losses give great figures at city speeds. Lab cycles also favor them. In many countries, a Yamaha R15 V4 claims above 50 km/l on ARAI, and owners often see mid-40s km/l in mixed use. That’s top-tier efficiency for a faired sport machine, even if the number drops at expressway pace.
Model-By-Model Notes You Can Trust
Suzuki GSX250R (~73.6 Mpg US)
Official spec sheets peg the GSX250R at roughly 73.6 mpg US. It’s a relaxed twin with tidy aerodynamics and a tall sixth gear. If you ride steady in the midrange, it rewards you with impressive range. Source: GSX250R specifications.
Honda CBR500R (~72 Mpg US)
Honda quotes 72 mpg US using its comparison procedure. In practice, you’ll usually sit in the 60s while commuting and in the 50s when pressing on. The charm is consistency across speeds. Source: CBR500R specifications.
Yamaha YZF-R3 (~56 Mpg US)
Yamaha lists an estimated 56 mpg US on the current R3 spec page. Expect mid-50s in calm use and 40s if you ride it on the cam.
Kawasaki Ninja 400 (~55 Mpg US)
Large owner samples trend to the mid-50s mpg US. It’s an efficient platform for the power on tap, especially when geared for highway cruising.
Yamaha R15 V4 (50–60 Km/L Claimed; ~45 Km/L Reported)
This 155 cc faired bike posts standout lab results on the ARAI cycle, with many owners reporting around 45 km/l in mixed use. It’s a strong answer in markets where the question “which sport bike has highest mileage?” leans toward small-cc sport machines.
KTM RC 125 (Low-40s Km/L Claimed)
Peppy in the city with true sport geometry. Expect low-40s km/l on smooth commutes, dipping on highways due to sustained high rpm.
Kawasaki Ninja 125 (~3.7 L/100 Km WMTC)
European brochure figures put the Ninja 125 near 3.7 L/100 km on the WMTC cycle (about 62 mpg US). Owner reports vary with country and gearing.
Why Your Mileage Swings: The Big Five
Two identical bikes can post wildly different numbers. These five variables move the needle the most:
Speed And Aero
Wind drag rises fast. A steady 60 mph cruise will always score better than 80 mph, even on the same route. Tuck behind the screen and keep it smooth.
Gearing And Rev Habit
Short-shifting into the tallest gear that pulls cleanly trims fuel burn. Holding a gear near redline for long stints does the opposite.
Tire Pressure
Underinflation wastes energy. Set pressures to the sticker for solo riding, check them cold, and recheck after big temperature swings.
Load And Accessories
Hard cases, wide mirrors, tall phone mounts—each adds drag. On a small engine, little bits add up. Keep the bike tidy for range days.
Maintenance
Fresh plugs, clean air filter, lubed chain, and correct idle settings keep the engine efficient. A rough chain alone can shave a couple mpg.
Quick Wins For Better Sport-Bike Mileage
| Riding Habit | What To Do | Typical Effect |
|---|---|---|
| Cruise Pace | Hold steady speeds; use the tallest clean-pull gear | Often +5–10 mpg US on twins |
| Air Pressure | Set tires to solo-rider spec before long rides | Reduces drag and heat build-up |
| Chain Care | Clean and lube every 500–800 km (or after rain) | Prevents 1–3 mpg US losses |
| Pack Light | Skip wide luggage; keep cockpit clutter low | Helps at highway speeds |
| Fuel Quality | Use the octane your manual specifies—no more | Stable knock control and smooth mapping |
Which Bike Suits Your Mix Of Roads?
Mostly City
Go small and faired. A Yamaha R15-class bike returns standout km/l numbers at urban speeds and slashes fuel spend. It answers which sport bike has highest mileage? for riders who rarely hold freeway pace.
Mixed Commute With Weekend Rides
Pick a thrifty twin in the 300–500 cc range. A YZF-R3, Ninja 400, or CBR500R keeps revs low at 60–70 mph yet stays fun on a backroad. Tank range stretches without making you feel short-changed.
Mostly Highway
CBR500R is the safe bet for mpg and stability. GSX250R can post eye-opening numbers too, though the smaller motor needs more patience for passes on fast routes.
FAQs You’re Probably Thinking (Answered Inline)
Are These Numbers Guaranteed?
No spec or owner average can promise your exact figure. Wind, elevation, traffic, and riding style change the result. The models listed here are efficient platforms that commonly deliver the posted numbers when ridden smoothly.
Why Do Lab Cycles Look So High?
Cycles like ARAI and WMTC run controlled speeds and loads. Real traffic adds starts, hills, and headwinds. Treat lab claims as best-case snapshots for comparison across models, not as a promise.
Bottom-Line Picks
Highest Real-World Mpg Sport Bikes You Can Buy Easily
- Suzuki GSX250R — Consistently ~70+ mpg US in steady use; approachable power; aerodynamic fairing.
- Honda CBR500R — Near-class-leading efficiency with grown-up stability; quoted at ~72 mpg US.
- Yamaha YZF-R3 — Simple, light, and thrifty; mid-50s mpg US is common when you keep it calm.
- Kawasaki Ninja 400 — Strong midrange and ~mid-50s mpg US by large owner samples.
When Small-Cc Models Win The Math
If your region sells the Yamaha R15 V4, KTM RC 125, or Kawasaki Ninja 125, their test-cycle numbers are tough to beat for stop-and-go riding. Just remember that sustained expressway speeds will pull them below their lab claims.
Sources And Method Notes
Manufacturer pages were used where possible to avoid speculation. See CBR500R specifications and GSX250R specifications for official mpg figures. Yamaha’s current R3 spec page lists a 56-mpg estimate, and large owner databases place the Ninja 400 near the mid-50s mpg US on average. In markets using ARAI/WMTC testing, small-cc faired models claim 50–60 km/l in labs, with most owners reporting lower—but still strong—results in mixed use.
