Technical Overview
2018 UM DSR EX Technical Analysis & Specification Breakdown
At the heart of the 2018 UM DSR EX enduro - offroad motorcycle, UM relies on a 124.2 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, maximum torque reaches 10.9 Nm (8 lb-ft) at 8,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 58.0 x 47.0 mm (2.3 x 1.9 inches) with a 12.8:1 compression ratio.
On the scales, the DSR EX measures 120 kg (265 lbs) dry. Rider ergonomics and chassis geometry center around a 910 mm (35.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,445 mm (56.9 in) wheelbase engineered for balanced agility and highway composure. The 6.3-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
