At the heart of the 2025 Yadea Kemper naked motorcycle, Yadea features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 40.2 HP (29.4 kW) while maximum torque reaches 570 Nm (420.4 lb-ft), transferring power to the rear wheel through a automatic gearbox.
On the scales, the Kemper measures 95 kg (209 lbs) dry, translating to a power-to-weight ratio of 0.42 HP/kg (2.36 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure.
