At the heart of the 2025 KTM SX-E 3 minibike, cross motorcycle, KTM features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 2.7 HP (2 kW) at 3,200 rpm while maximum torque reaches 10.5 Nm (7.7 lb-ft), transferring power to the rear wheel through a 1-speed gearbox and chain final drive.
On the scales, the SX-E 3 measures 39 kg (86 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 682 mm (26.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,025 mm (40.4 in) wheelbase engineered for quick, flickable steering geometry.
