The engine on the scooter is a four-stroke air-cooled single-cylinder unit that pumps out 3.75 horsepower at 8,000 revolutions per minute (RPM) and 2.15 pound-feet of torque at 6,500 RPM.

Two intake valves are placed on the engine""s cylinder, and the entire unit depends on fueling from a carburetor.
Each engine on the 2008 SYM Mio is paired with a Continuously Variable Transmission, a type of automatic gearbox that improves engine efficiency by choosing from an unlimited number of effective gear ratios. Going on each 2008 SYM Mio is a 1.3-gallon (4.8-liter) gas tank.
For its stopping power, the 2008 SYM Mio relies on a 6.3-inch (180-mm) dual disc brake at the front; and a smaller, 3.7-inch (95-mm) drum brake at the back. Its suspension comprises a telescopic fork at the front and twin-sided swing arm with shock absorber at the back. Each 2008 SYM Mio rides on ten-inch aluminum wheels fitted with tubed tires.
The 2008 SYM Mio uses a steel frame for sturdiness, with other parts including front and rear fenders, fork guards, belt guard and exhaust guard. The 2008 Mio comes in a Coffee/White, Orange/White or White finish. The one-piece vinyl seat on the scooter is big enough for two people; and storage consists of under-seat and lockable compartments, as well as helmet accommodation.
