Positioned in Benelli's naked motorcycle lineup, the 2012 Benelli TNT 899 pairs a 899 cc (54.9 cu in) liquid-cooled in-line three, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 129 HP (94.2 kW) at 8,500 rpm while maximum torque reaches 110 Nm (81.1 lb-ft) at 5,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 143.5 HP per liter and a 3,250 rpm working window between peak torque (5,250 rpm) and peak power (8,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the TNT 899 measures 215 kg (474 lbs) wet (curb), translating to a power-to-weight ratio of 0.6 HP/kg (1.67 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.
