Anti-lock brakes arrived on Vietnamese scooters years ago, but the underbone world is more conservative. Here is exactly what the manufacturers publish (retrieved 23 September 2026) - and no more.
The verified ABS picture
Yamaha’s Exciter 155 VVA page lists ABS on limited ABS versions; the standard Exciter runs a front hydraulic disc and rear disc without ABS. Honda publishes no ABS claim for any listed underbone - Wave Alpha, Blade, Wave RSX, Future 125, Super Cub C125, CT125, Winner R or CBR150R pages all stop at brake hardware descriptions, and several do not itemise brake versions at all. Anyone telling you a specific ABS fitment beyond these published facts is guessing.
What the class actually offers
Discs, mostly front-only. The Sirius RC pairs a front hydraulic disc with a rear drum; the Blade Sport runs alloy wheels and a front disc while other Blade versions use a front drum; the Super Cub, CT125, Winner R and CBR150R pages do not itemise their brake layouts on the retrieved pages. Disc-versus-drum trade-offs are covered in our brakes guide.
Does it matter?
ABS prevents locked-wheel falls under panic braking - most relevant on wet Hanoi paint lines and mountain descents. In the underbone class, the practical substitutes are technique (our emergency-braking guide) and maintenance (the brake-checks basics), because most of the fleet you can rent or buy cheaply will have no ABS.
Rental context
Our price-published classes are the semi-automatic Wave and Sirius - front disc or drum, no ABS. Riders should assume no ABS unless a specific model page proves otherwise, and contact us to confirm current availability of any specific model.
