At the heart of the 2025 Fantic Stealth 125 naked motorcycle, Fantic pairs a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 14.8 HP (10.8 kW) at 10,250 rpm while maximum torque reaches 11.2 Nm (8.3 lb-ft) at 6,500 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 3,750 rpm working window between peak torque (6,500 rpm) and peak power (10,250 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 Stealth 125 measures 129 kg (284 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (8.72 kg per horsepower). Rider ergonomics and chassis geometry center around a 810 mm (31.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,355 mm (53.3 in) wheelbase engineered for quick, flickable steering geometry. The 12.5-liter (3.3 US gal) fuel tank paired with a rated consumption of 2 L/100 km provides an estimated theoretical range of roughly 625 km (388 miles) between fill-ups.
