Most automatic scooters sold and rented in Vietnam sit in one of two engine classes: around 110 cc or around 125 cc. The difference is real but smaller than the marketing suggests - here is what the manufacturers’ own figures (retrieved 23 September 2026) show, and what the classes mean for licences and daily riding.
The verified numbers
- Honda Vision 110 (109.5 cc): 6.59 kW, 9.29 Nm
- Yamaha Janus 125 (124.9 cc): 7.0 kW, 9.6 Nm
- Honda Lead 125 (124.8 cc): 8.22 kW, 11.7 Nm
- Yamaha FreeGo 125 (124.9 cc): 7.0 kW, 9.0 Nm
- Honda Air Blade 160 (156.9 cc): 11.2 kW, 14.8 Nm
Note how much overlap there is: a 125 is not automatically stronger than every 110-160 - the Lead makes more torque at lower revs than several larger engines, and engine tuning matters as much as capacity. Our power and torque explainer covers how to read these figures.
Licence implications
Engine capacity determines which Vietnamese licence class covers a bike - anything up to 125 cc falls in the A1 class, while smaller categories apply under 50 cc. The details are in our licence guides: what the A1 licence lets you ride and the 50 cc licence rules. If you hold a foreign licence or IDP, check those guides before choosing a rental.
What you actually feel
- Solo city commuting: a 110 is enough. Weight and agility matter more than power below 50 km/h.
- Two-up riding: the 125 class pulls away from lights with a passenger more comfortably - the torque figures above show why.
- Longer weekend routes: sustained 60-70 km/h running is where the 125’s headroom shows.
- Economy: the 110 class generally posts lower published consumption - see the fuel economy comparison.
How to choose
Match the class to your use, not your ego: solo commuters save money and fuel on a 110; riders carrying passengers or leaving the city benefit from a 125. Renters can try both - Nguyen Tu publishes rates for the Vision (110 class, 200,000 VND/day); contact us to confirm current availability of any specific model.
