Engineered by Yamaha for the scooter motorcycle segment, the 2018 Yamaha Mio Sporty utilizes a 113.7 cc (6.9 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 8 HP (5.9 kW) at 8,000 rpm while maximum torque reaches 7.4 Nm (5.5 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 70.4 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Mio Sporty measures 95 kg (209 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (11.88 kg per horsepower). Rider ergonomics and chassis geometry center around a 745 mm (29.3 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,240 mm (48.8 in) wheelbase engineered for quick, flickable steering geometry. The 3.7-liter (1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
