Technical Overview
2021 Um Xtreet 180R Technical Analysis & Specification Breakdown
Positioned in Um's sport motorcycle lineup, the 2021 Um Xtreet 180R pairs a 179.9 cc (11 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 15.4 HP (11.2 kW) at 8,500 rpm while maximum torque reaches 13.5 Nm (10 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 85.6 HP per liter and a 2,000 rpm working window between peak torque (6,500 rpm) and peak power (8,500 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 Xtreet 180R measures 128 kg (282 lbs) dry, translating to a power-to-weight ratio of 0.12 HP/kg (8.31 kg per horsepower). Rider ergonomics and chassis geometry center around a 870 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 15.5-liter (4.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
