Technical Overview
2023 Factory Bike M55 Technical Analysis & Specification Breakdown
Built around Factory's minibike, cross motorcycle platform, the 2023 Factory Bike M55 utilizes a 55 cc (3.4 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 9 HP (6.6 kW), transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 163.6 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Bike M55 measures 40 kg (88 lbs) dry, translating to a power-to-weight ratio of 0.23 HP/kg (4.44 kg per horsepower). Rider ergonomics and chassis geometry center around a 575 mm (22.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 915 mm (36 in) wheelbase engineered for quick, flickable steering geometry. The 1.5-liter (0.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 45 km/h (28 mph).
