Positioned in Yamaha's scooter motorcycle lineup, the 2020 Yamaha Y15ZR utilizes a 124 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 15.2 HP (11.1 kW) at 8,500 rpm while maximum torque reaches 13.8 Nm (10.2 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox. With a specific output of 122.6 HP per liter and a 1,500 rpm working window between peak torque (7,000 rpm) and peak power (8,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the Y15ZR measures 115 kg (254 lbs) wet (curb), translating to a power-to-weight ratio of 0.13 HP/kg (7.57 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 4.2-liter (1.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
