The Janus and the Lead sit at opposite ends of the practical 125 spectrum: Yamaha’s entry model is about light weight and low cost; Honda’s Lead is about the biggest bay in the class. Verified figures from the official pages (retrieved 23 September 2026).
Engine and economy
The Janus’s Blue Core 124.9 cc engine makes 7.0 kW at 8,000 rpm and 9.6 Nm at 5,500 rpm, with published consumption of 1.98 litres/100 km from a 4.2-litre tank and Stop & Start. Honda’s Lead page did not publish output figures in our retrieval; what is verified is the 125 cc eSP+ four-valve liquid-cooled engine with PGM-FI. On published economy the Janus is the documented sipper - see the fuel economy comparison.
Weight and storage
Janus: 97 kg kerb, 15.3-litre underseat bay, USB port, hydraulic front disc. Lead: 37-litre underseat bay holding two full-face helmets, with an ABS version available. This is the whole decision in two numbers - the Janus wins every parking-speed contest, the Lead wins every cargo contest.
Price
The Janus lists from 29,151,000 VND - the value anchor of the 125 class. The Lead costs more and gives you the bay; check Honda’s current Lead pricing when buying.
Verdict
Minimum weight and price, maximum familiarity: Janus. Family-and-cargo duties: Lead, no contest. Neither is among Nguyen Tu’s price-published rental models - contact us to confirm current availability. If you want a middle path with more storage than the Janus and more sport than the Lead, the FreeGo and Vario 125 comparisons cover it.
