At the heart of the 2008 Benelli BX 505 Enduro enduro - offroad motorcycle, Benelli utilizes a 505 cc (30.8 cu in) single cylinder, four-stroke layout. In factory specification, peak output is rated at 59.7 HP (43.6 kW) at 8,500 rpm while maximum torque reaches 50 Nm (36.9 lb-ft) at 5,750 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 118.2 HP per liter and a 2,750 rpm working window between peak torque (5,750 rpm) and peak power (8,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
Rider ergonomics and chassis geometry center around a 960 mm (37.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,450 mm (57.1 in) wheelbase engineered for balanced agility and highway composure. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
