2023 Factory Bike M4F Technical Analysis & Specification Breakdown

Engineered by Factory Bike for the enduro - offroad motorcycle segment, the 2023 Factory Bike M4F pairs a 250 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 26 HP (19 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 104 HP per liter, 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 M4F measures 113 kg (249 lbs) dry, translating to a power-to-weight ratio of 0.23 HP/kg (4.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 6.5-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
