Two budget 110s, nearly the same price, very different characters. All figures below come from the official Honda Vietnam and Yamaha Vietnam product pages (retrieved 23 September 2026).
Engines
Blade: 109.1 cc air-cooled single, 6.18 kW at 7,500 rpm, 8.65 Nm at 5,500 rpm, Euro 3 emissions. Sirius: 110.3 cc air-cooled SOHC single, 5.9 kW at 8,000 rpm, 9.0 Nm at 5,000 rpm with a wet multi-plate centrifugal clutch. Both use four-speed rotary gearboxes; the Blade offers kick and electric start, the Sirius pairs a compact 1,890 x 665 x 1,035 mm body with 17-inch wheeled agility.
Economy
Sirius: 2.08 L/100 km from 4.2 L. Blade: 1.85 L/100 km from 3.7 L. Per-litre the Blade is the thriftier of the two on paper; the Sirius carries more fuel overall.
Ground clearance and brakes
The Blade’s 141 mm of clearance is the standout number in the 110 class - useful on kerbs, ramps and rural edges - versus the Sirius’s compact urban stance. On braking, the Blade Sport version and the Sirius disc and RC versions all add a front disc over the base drums; buy a disc version whichever brand you choose, and see our disc versus drum comparison for why.
Weight and price
Blade: 98-99 kg by version, from 21,943,637 VND. Sirius: 100 kg wet, with the RC alloy version at 21,993,000 VND and cheaper drum and disc versions below it.
Verdict
Blade for economy, clearance and the option of a kick-starter; Sirius for the roomier version ladder at lower entry prices. Both are honest machines - read the full Blade and Sirius reviews before choosing.
