Vietnamese underbones come in versions, and the version is often more important than the model. The manufacturers’ own pages name the differences (retrieved 23 September 2026) - this guide collects them and explains the trade-offs.
The published version differences
Honda Blade: a Sport version with alloy wheels and a front disc, alongside spoked-wheel drum and spoked disc versions - with published weights differing (98 kg spoked drum, 99 kg spoked disc/alloy). Future 125 FI: three versions at from 30,622,909 VND, equipment differences not itemised on the page. Yamaha Sirius: the RC alloy-wheel version with front hydraulic disc and rear drum; drum versions also exist per Yamaha’s page. Yamaha Exciter 155 VVA: limited ABS versions carry ABS, the standard bike does not. Wave Alpha, Wave RSX, Super Cub, CT125, Winner R, CBR150R: versions not itemised on the retrieved pages.
The two version axes that matter
Brakes: front disc versus front drum is the single most safety-relevant version choice in the class - our disc-versus-drum guide covers the wet-weather difference, and our ABS guide covers what the class mostly does not offer. Wheels: alloy versus spoked pairs with the brake choice (discs usually arrive on alloys); our wheels explainer covers the puncture and maintenance trade-offs.
How to buy a version
Decide disc first - it is worth the premium for anyone riding in rain or carrying loads - then take the wheel type that comes with it. Verify the version in the paperwork, not the badge: trim badges are easy to add aftermarket.
Rental note
Rental fleets typically run the standard commuter versions; our price-published Wave and Sirius classes (150,000 VND/day) may be disc or drum by unit - ask when booking. Contact us to confirm current availability of a specific version.
