Engineered by Macbor for the custom - cruiser motorcycle segment, the 2022 Macbor Rockster Flat 125 relies on a 124.7 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 10.5 HP (7.6 kW) at 8,500 rpm while maximum torque reaches 9.5 Nm (7 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 84.2 HP per liter and a 2,500 rpm working window between peak torque (6,000 rpm) and peak power (8,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the Rockster Flat 125 measures 127 kg (280 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.1 kg per horsepower). Rider ergonomics and chassis geometry center around a 730 mm (28.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,435 mm (56.5 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.
