2021 Um DSR 125 Technical Analysis & Specification Breakdown
Engineered by Um for the enduro - offroad motorcycle segment, the 2021 Um DSR 125 relies on a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 56.5 x 49.5 mm (2.2 x 1.9 inches) with a 9.2:1 compression ratio.
On the scales, the DSR 125 measures 122 kg (269 lbs) dry. Rider ergonomics and chassis geometry center around a 890 mm (35 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,352 mm (53.2 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
