Technical Overview
2021 Um Renegade Sport 140 Technical Analysis & Specification Breakdown
At the heart of the 2021 Um Renegade Sport 140 sport motorcycle, Um features a 137.8 cc (8.4 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 11 HP (8 kW) at 7,900 rpm while maximum torque reaches 10.5 Nm (7.8 lb-ft) at 5,600 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 79.8 HP per liter and a 2,300 rpm working window between peak torque (5,600 rpm) and peak power (7,900 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
Rider ergonomics and chassis geometry center around a 756 mm (29.8 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,350 mm (53.1 in) wheelbase engineered for quick, flickable steering geometry. The 10.22-liter (2.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
