At the heart of the 2005 Aprilia MX 125 super motard motorcycle, Aprilia utilizes a 124.8 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 24.1 HP (17.6 kW) at 10,500 rpm while maximum torque reaches 17 Nm (12.5 lb-ft) at 10,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 193.1 HP per liter and a 500 rpm working window between peak torque (10,000 rpm) and peak power (10,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the MX 125 measures 126 kg (278 lbs) wet (curb), translating to a power-to-weight ratio of 0.19 HP/kg (5.23 kg per horsepower). Rider ergonomics and chassis geometry center around a 870 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,480 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 130 km/h (81 mph).
