Built around Quantya's minibike, cross motorcycle platform, the 2012 Quantya MMX Junior features a purpose-built air-cooled electric configuration. In factory specification, peak output is rated at 7.4 HP (5.4 kW) while maximum torque reaches 16 Nm (11.8 lb-ft), transferring power to the rear wheel through chain final drive.
On the scales, the MMX Junior measures 74 kg (163 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10 kg per horsepower). Rider ergonomics and chassis geometry center around a 860 mm (33.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,270 mm (50 in) wheelbase engineered for quick, flickable steering geometry.
