Engineered by Gilera for the enduro - offroad motorcycle segment, the 1991 Gilera Apache 125 utilizes a 124 cc (7.6 cu in) liquid-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 29.3 HP (21.4 kW) at 9,900 rpm while maximum torque reaches 18.5 Nm (13.6 lb-ft) at 8,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 236.3 HP per liter and a 1,650 rpm working window between peak torque (8,250 rpm) and peak power (9,900 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Apache 125 measures 135 kg (298 lbs) wet (curb), translating to a power-to-weight ratio of 0.22 HP/kg (4.61 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 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 5-liter (1.3 US gal) fuel tank paired with a rated consumption of 6 L/100 km provides an estimated theoretical range of roughly 83 km (52 miles) between fill-ups, while factory top speed is listed at 143 km/h (89 mph).
