Engineered by Benelli for the touring motorcycle segment, the 2023 Benelli TRK 251 utilizes a 249.2 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 25.8 HP (18.8 kW) at 9,250 rpm while maximum torque reaches 21.1 Nm (15.6 lb-ft) at 8,000 rpm. With a specific output of 103.5 HP per liter and a 1,250 rpm working window between peak torque (8,000 rpm) and peak power (9,250 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 TRK 251 measures 153 kg (337 lbs) dry, translating to a power-to-weight ratio of 0.17 HP/kg (5.93 kg per horsepower). Rider ergonomics and chassis geometry center around a 835 mm (32.9 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,380 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 17-liter (4.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
