Built around Macbor's custom - cruiser motorcycle platform, the 2021 Macbor Rockster Flat 125 pairs a 124.7 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 52.4 x 57.8 mm (2.1 x 2.3 inches) with a 9.5:1 compression ratio.
On the scales, the Rockster Flat 125 measures 142 kg (313 lbs) dry. Rider ergonomics and chassis geometry center around a 720 mm (28.3 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 paired with a rated consumption of 1.9 L/100 km provides an estimated theoretical range of roughly 711 km (442 miles) between fill-ups.
Within MotoLibrary's Macbor archive, this model family spans 5 indexed model years from 2018 to 2022, allowing buyers to track year-over-year changes in emissions tuning, weight and equipment.
