Positioned in Yamaha's scooter motorcycle lineup, the 2015 Yamaha EC-03 features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 1.9 HP (1.4 kW) at 2,550 rpm while maximum torque reaches 9.6 Nm (7.1 lb-ft) at 280 rpm, transferring power to the rear wheel through a automatic gearbox.
On the scales, the EC-03 measures 56 kg (123 lbs) dry. 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 1,080 mm (42.5 in) wheelbase engineered for quick, flickable steering geometry.
