Range matters more in Vietnam than spec-sheet horsepower: long stretches between reliable petrol stations on rural trips, and city riding where you simply want fewer fuel stops. There is no official range figure for most scooters, so this guide does the honest arithmetic - verified tank size multiplied by the manufacturer’s published economy (all figures retrieved 23 September 2026) - and clearly labels the results as implied, not claimed.

The implied-range ranking

Model Tank Published economy Implied range per fill
Yamaha NMAX 155 7.1 L 2.26 L/100km about 314 km
Honda SH160i 7.0 L 2.34 L/100km about 299 km
Honda SH Mode 125 5.6 L 2.16 L/100km about 259 km
Yamaha NVX 155 5.5 L 2.19 L/100km about 251 km (Yamaha also claims up to 200 km)
Honda Vario 125 5.5 L 2.11 L/100km about 260 km (Honda states about 260 km)
Honda Vario 160 5.5 L 2.20 L/100km about 250 km
Yamaha Gear 125 Hybrid 5.1 L 1.7 L/100km about 300 km
Yamaha Janus 125 4.2 L 1.98 L/100km about 212 km
Yamaha Lexi 155 4.2 L 2.19 L/100km about 192 km
Yamaha FreeGo 125 3.9 L 2.03 L/100km about 192 km

Big tank plus small thirst wins: the NMAX and Gear 125 lead on implied range; the Lexi and FreeGo carry the smallest tanks in their classes.

What eats real-world range

Manufacturer economy figures come from controlled conditions - real range varies with load, speed, temperature, terrain and riding style, so treat the table as a ceiling, not a promise. Two-up riding, high-speed ring-road running and stop-start traffic all cut it. Our fuel economy comparison and economy-improvement guide cover the levers you control.

Practical advice

Plan rural trips around fuel stops, not the tank’s ceiling, and do not run a unfamiliar scooter to fumes - fuel quality and gauge accuracy vary (our fuel gauge article explains why). Nguyen Tu’s rental scooters come with the fuel policy in our rental FAQ - contact us to confirm current availability of any specific model.
