Engineered by Benelli for the naked motorcycle segment, the 2017 Benelli TNT 300 pairs a 300 cc (18.3 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 38 HP (27.7 kW) at 10,000 rpm while maximum torque reaches 27.4 Nm (20.2 lb-ft) at 9,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 126.7 HP per liter and a 1,000 rpm working window between peak torque (9,000 rpm) and peak power (10,000 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 300 measures 196 kg (432 lbs) wet (curb), translating to a power-to-weight ratio of 0.19 HP/kg (5.16 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 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 15.97-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
