Engineered by Benelli for the naked motorcycle segment, the 2015 Benelli TNT 899 utilizes a 899 cc (54.9 cu in) liquid-cooled in-line three, four-stroke layout. In factory specification, peak output is rated at 120 HP (87.6 kW) at 9,500 rpm while maximum torque reaches 88 Nm (64.9 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 133.5 HP per liter and a 1,500 rpm working window between peak torque (8,000 rpm) and peak power (9,500 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 899 measures 215 kg (474 lbs) wet (curb), translating to a power-to-weight ratio of 0.56 HP/kg (1.79 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,443 mm (56.8 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
