At the heart of the 2021 Kollter ES1-S super motard motorcycle, Kollter features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 5.1 HP (3.7 kW) while maximum torque reaches 50 Nm (36.9 lb-ft) at 5,000 rpm, transferring power to the rear wheel through chain final drive.
On the scales, the ES1-S measures 109 kg (240 lbs) dry, translating to a power-to-weight ratio of 0.05 HP/kg (21.37 kg per horsepower). Rider ergonomics and chassis geometry center around a 665 mm (26.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,470 mm (57.9 in) wheelbase engineered for balanced agility and highway composure.
