Yamaha Mio Aerox 155
The Yamaha Mio Aerox 155 has a top speed of ~125 km/h, produces 15.4 hp and weighs 125 kg. Motoryk rates it 7.5/10.
The Yamaha Aerox 155 (sold as the Mio Aerox 155 in Southeast Asian markets) was introduced in 2016 as a sporty maxi-scooter targeting young urban riders seeking performance beyond typical 125cc scooters. It was built on Yamaha's BluCore VVA (Variable Valve Actuation) platform, making it one of the first scooters in its segment to feature variable valve timing technology. Its aggressive NVX/Aerox styling and strong 155cc engine helped it become a best-seller in markets like Indonesia, Thailand, and the Philippines.

What Buyers Should Know
VVA Tech Advantage
The Aerox 155 features Yamaha's Variable Valve Actuation (VVA) system, which switches between two valve timing modes for both low-end torque and high-end power — rare in scooters at this price point.
Watch the CVT Belt
The CVT belt and roller weights are common wear items that require inspection every 8,000–10,000 km. Neglecting them causes sluggish acceleration and can lead to costly transmission damage.
Strong Resale Value
The Aerox 155 holds resale value well in Southeast Asian markets due to high brand trust and strong parts availability. A well-maintained unit typically retains 70–80% of its value after two years.

Used Buyer Review
"A genuinely fast scooter that rewards buyers who inspect CVT carefully."
$2,500-$4,200 usedThe Aerox 155 is genuinely quick for a scooter — that VVA-equipped engine pulls hard past 6,000rpm in a way that'll surprise you at traffic lights. Used examples from 2017 onwards are generally solid, but check the variator rollers carefully because owners who commute hard rarely service them on schedule. Belt wear is the silent killer here — budget for a replacement if you can't verify the history. Build quality is decent but not exceptional. Plastics scratch easily and the underseat storage is surprisingly shallow for a machine this size. The dual-channel ABS on later models is worth hunting for specifically — early non-ABS versions bite hard on wet roads. Suspension is firm for a scooter, which actually helps confidence at speed but gets tiresome on broken urban tarmac. Overall it's a legitimate performance scooter that earns its price premium over basic 125s. Just inspect the CVT system thoroughly and don't let a seller talk you out of a test ride.
