At the heart of the 2023 Benelli TNT 135 minibike, sport motorcycle, Benelli pairs a 134.7 cc (8.2 cu in) oil & air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 12.5 HP (9.1 kW) at 9,000 rpm while maximum torque reaches 10.8 Nm (8 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 92.8 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the TNT 135 measures 116 kg (256 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.28 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,215 mm (47.8 in) wheelbase engineered for quick, flickable steering geometry. The 7.2-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
