History of the Yamaha Mio
Yamaha developed the Mio in 2003 after studying the sales and technical performance of its predecessor, the Nouvo. The scooter was launched in Southeast Asia and reached Malaysia in March 2004, where Hong Leong Yamaha renamed it the Yamaha Ego. By 2007 there were about 76,000 Ego customers in Malaysia.
The 2006 model brought a facelift and a new name: outside Malaysia the scooter became the Mio Soul. It gained a V-shaped headlight for better night vision, new body stripes and a redesigned tail light with a retroreflector, while the engine stayed the same as in 2003. In Malaysia the revised model was launched as the Ego S in October 2007.
The Mio changed technically in 2012, when the carburettor gave way to fuel injection and the CVT gained a larger pulley, with a DiaSil cylinder and a forged piston to reduce engine weight. In 2014 the whole range moved to a 125 cc engine with the largest CVT pulley and a short-range belt, giving more constant speed and easier acceleration uphill. The DiaSil cylinder, forged piston and lighter body also improved fuel economy. Together with the Nouvo, the Mio became a platform for customisation in Thailand, Malaysia, Indonesia, Vietnam and the Philippines, and Yamaha has sold many derivatives under names including Mio Soul, Mio J, Mio M3, Mio S, Mio Gear and Mio Fazzio.
