European emissions labels appear across Vietnamese model pages, and they signal more than environmental intent - they mark where a bike sits in Honda and Yamaha’s technology generations. Only manufacturer-published claims below (retrieved 23 September 2026).
What the manufacturers actually publish
Honda’s Blade page lists Euro 3. Honda’s SH Mode 125 page lists EURO 4 (a scooter, but the clearest label in the range). Most underbone pages - Wave Alpha, Wave RSX, Future 125, Super Cub, CT125, Winner R, CBR150R - publish no emissions-class claim at all on the retrieved pages, and no claim should be invented for them. Yamaha’s Sirius and Exciter pages likewise publish no emissions class.
Why labels lag the market
Euro 3 machines are typically earlier-engine-generation products still on sale because they remain cheap, simple and demand-proven - the Blade being the honest example. Euro 4 generally implies injection, tighter fuelling control and updated engine management, which is part of why the modern injected machines (like the Wave RSX with PGM-FI) post better economy figures.
What it means for a buyer
Emissions class is a proxy, not a verdict: a Euro 3 Blade still runs reliably and cheaply, while an unlabelled modern bike may be cleaner still. The label matters most if you care about fuel economy and long-term parts evolution - our injection explainer connects those dots. For renters, the question is moot: our price-published classes are the Wave and Sirius at 150,000 VND per day - contact us to confirm current availability. For the scooter side of the story, our Euro 4 scooters guide covers the automatic range.
