2023 Factory Bike J11 Technical Analysis & Specification Breakdown

At the heart of the 2023 Factory Bike J11 cross - motocross motorcycle, Factory Bike pairs a 250 cc (15.3 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 24 HP (17.5 kW), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 96 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.
