Yamaha Mio

The Yamaha Mio is a scooter with a CVT transmission made by Yamaha Motor. It was introduced for the Southeast Asia market in 2003 as the successor of the Nouvo. In Malaysia, this model is known as Yamaha Ego. As 2007, there were some 76,000 Ego customers in Malaysia. Together with its counterpart the Yamaha Nouvo, the Mio/Ego is a platform for customization in Thailand, Malaysia, Indonesia, Vietnam and the Philippines.

2003
Based on sales performance and also technical studies of its predecessor Yamaha Nouvo by Yamaha's R&D team, in 2003 Yamaha Motor successfully developed and marketed Yamaha Mio in Southeast Asia countries and in March 2004, Hong Leong Yamaha (HLY) introduced this model in Malaysia, renaming it Yamaha Ego.

2006
2006 brought some new changes to the Mio. It was renamed and since then has been known as the Yamaha Mio Soul (except for the Malaysian market).

Physical change also can be seen in the 2006 model specifications. This includes an aggressive facelift by the Yamaha team: it features newly design V-shape headlight for better vision range at night and new body stripes. The engine, however, remained the same as in the 2003 model. For safety concerns, the taillight was re-designed with the addition of a retroreflector device.

For the Malaysian market, HLY again renamed the scooter as the Yamaha Ego S (S for Sport) and launched it in October 2007. The launch ceremony took place at the Sheraton Subang Hotel in Kuala Lumpur, Malaysia.

2012
2012 changed from carburetor to fuel injected with big pulley CVT, with DiaSil cylinder and forged piston to reduce engine weight.

2014
In 2014, all models switched to a new 125cc engine, using biggest size pulley in CVT and short range belt CVT, making more constant speed and easier acceleration in uphill. DiaSil cylinder engine with forged piston and lighter body structure reduce weight, this scooter has different fuel efficiency, better fuel economy than the previous version.
