Honda sells two 110-class Waves in Vietnam, and from the outside they look nearly identical. The difference is bigger than the badges suggest: Honda Vietnam publishes different engines, tanks and prices for the Wave Alpha and the Wave RSX (all figures retrieved 23 September 2026).

The core difference

The Wave Alpha is the entry point: 109.2 cc, air-cooled, 6.12 kW at 7,500 rpm and 8.44 Nm at 5,500 rpm, electric start, a 3.7-litre tank and a manufacturer list price of 18,841,091 VND. The Wave RSX sits above it: the same 109.2 cc capacity but with Honda’s PGM-FI electronic fuel injection, more power (6.46 kW at 7,500 rpm), more torque (8.70 Nm at 6,000 rpm), a bigger 4.0-litre tank and a list price of 25,664,727 VND. Both use a four-speed rotary gearbox with no clutch lever - the semi-automatic format our scooter-versus-semi-automatic guide covers in detail.

Fuel economy

This is where the RSX justifies itself. Honda publishes 1.72 L/100 km for the Wave Alpha and 1.56 L/100 km for the RSX, and the RSX carries 0.3 litres more fuel. Those are manufacturer figures under standard test conditions - real consumption always varies with load, speed and traffic. Over a month of daily Hanoi commuting, the difference is real but modest.

Size, weight and practicalities

The RSX is slightly longer (1,922 vs 1,913 mm), a touch lower at the seat (760 vs 770 mm) and marginally heavier (98 vs 96 kg). Both ride 17-inch wheels with 70/90-17 front and 80/90-17 rear tyres. The RSX adds a U-box that holds one half helmet and a 4-in-1 key system - genuinely useful if you park on the street. The Alpha lists no storage.

Which Wave makes sense for you?

Renting for days or weeks in Hanoi: the Wave Alpha is the price-published rental class at 150,000 VND per day in our fleet, and for city riding its simpler specification is a virtue. Contact us to confirm current availability of either model. Buying: the roughly 6.8-million-VND list-price gap buys injection, a bigger tank and storage, and the RSX is the better long-distance tool. Riders who plan weekend trips beyond Hanoi should read our Wave RSX versus Sirius comparison too - the RSX’s nearest rival is not its own sibling.
