Technical Overview
2018 UM Scrambler Sport Technical Analysis & Specification Breakdown
Engineered by UM for the sport motorcycle segment, the 2018 UM Scrambler Sport utilizes a 124.7 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 9.7 HP (7.1 kW) at 9,500 rpm while maximum torque reaches 9.2 Nm (6.8 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 77.8 HP per liter and a 3,500 rpm working window between peak torque (6,000 rpm) and peak power (9,500 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 Scrambler Sport measures 130 kg (287 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (13.4 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,340 mm (52.8 in) wheelbase engineered for quick, flickable steering geometry. The 10.5-liter (2.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
