Built around Benelli's naked motorcycle platform, the 2011 Benelli Tre-K 899 features a 899 cc (54.9 cu in) liquid-cooled in-line three, four-stroke configuration. In factory specification, peak output is rated at 106.6 HP (77.8 kW) at 9,000 rpm while maximum torque reaches 88 Nm (64.9 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 118.6 HP per liter and a 1,500 rpm working window between peak torque (7,500 rpm) and peak power (9,000 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 Tre-K 899 measures 215 kg (474 lbs) dry, translating to a power-to-weight ratio of 0.5 HP/kg (2.02 kg per horsepower). Rider ergonomics and chassis geometry center around a 840 mm (33.1 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,514 mm (59.6 in) wheelbase engineered for balanced agility and highway composure. The 22-liter (5.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
