Technical Overview
2023 Benelli BKX 250 S Technical Analysis & Specification Breakdown
Built around Benelli's enduro - offroad motorcycle platform, the 2023 Benelli BKX 250 S pairs a 249.2 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 25.5 HP (18.6 kW) at 9,250 rpm while maximum torque reaches 21.1 Nm (15.6 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 102.3 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 BKX 250 S measures 164 kg (362 lbs) wet (curb), translating to a power-to-weight ratio of 0.16 HP/kg (6.43 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 1,432 mm (56.4 in) wheelbase engineered for balanced agility and highway composure. The 13.5-liter (3.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
