Well, I have been riding my Yamaha Nouvo since August, 2004. I have driven nearly 30,000 km on it, mostly in Saigon but I have made many trips to Bien Hoa and the Mekong Delta. I actually got the first Yamaha Nouvo model but but just 3 months later, the Nouvo II was released in Vietnam. This proved to be one of the most successful Nouvo models here in Saigon. Back in August, 2004, I had one of the few Nouvos in the city. By the summer of 2005, the Nouvo IIs were everywhere.
Last year the Nouvo III started selling in Saigon. They are just as popular as the original two models. The Honda Click, and later, the Air Blade were released to compete with the Nouvo. Suzuki released the 125cc Hayate which looks more like a Nouvo rip-off. Still, all three scooter models are very popular in the city.
I just read that Yamaha has started selling a 135cc Yamaha Nouvo Elegance in Thailand. That means that roughly in December, based on past experience, the Nouvo Elegance will be sold in Saigon (New models are normally introduced before the New Year at a higher price).
Since my motorbike is beginning to show it’s age, I will probably replace my Nouvo I with the Nouvo Elegance. The reviews stated that it actually gets better gas mileage then the venerable Air Blade.
