2019 Swm SM 125 R Factory Technical Analysis & Specification Breakdown
Positioned in Swm's super motard motorcycle lineup, the 2019 Swm SM 125 R Factory relies on a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 58.0 x 47.2 mm (2.3 x 1.9 inches) with a 12.8:1 compression ratio.
On the scales, the SM 125 R Factory measures 110 kg (243 lbs) dry. Rider ergonomics and chassis geometry center around a 914 mm (36 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,500 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 12.8-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
