2021 Fantic XEF 125 Competition Technical Analysis & Specification Breakdown

At the heart of the 2021 Fantic XEF 125 Competition enduro - offroad motorcycle, Fantic relies on a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 9,750 rpm while maximum torque reaches 11.8 Nm (8.7 lb-ft) at 6,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 118.7 HP per liter and a 3,000 rpm working window between peak torque (6,750 rpm) and peak power (9,750 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the XEF 125 Competition measures 108 kg (238 lbs) dry, translating to a power-to-weight ratio of 0.14 HP/kg (7.3 kg per horsepower). Rider ergonomics and chassis geometry center around a 915 mm (36 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 7.5-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
