Positioned in Benelli's minibike, sport motorcycle lineup, the 2020 Benelli TNT 135 relies on a 134.7 cc (8.2 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 11.3 HP (8.2 kW) at 9,500 rpm while maximum torque reaches 10 Nm (7.4 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 83.9 HP per liter and a 2,500 rpm working window between peak torque (7,000 rpm) and peak power (9,500 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 121 kg (267 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.71 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.
