Built around Benelli's naked motorcycle platform, the 2017 Benelli TNT 25 features a 249.2 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 24.5 HP (17.9 kW) at 9,000 rpm while maximum torque reaches 21 Nm (15.5 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 98.3 HP per liter and a 1,500 rpm working window between peak torque (7,500 rpm) and peak power (9,000 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 TNT 25 measures 159 kg (351 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.49 kg per horsepower). Rider ergonomics and chassis geometry center around a 795 mm (31.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,400 mm (55.1 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
