At the heart of the 2021 Yamaha Delight 125 scooter motorcycle, Yamaha features a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 8.3 HP (6.1 kW) at 7,000 rpm while maximum torque reaches 9.8 Nm (7.2 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 66.4 HP per liter and a 2,000 rpm working window between peak torque (5,000 rpm) and peak power (7,000 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 Delight 125 measures 99 kg (218 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (11.93 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,275 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
