Xtreet RC

2018 UM Xtreet RC Technical Analysis & Specification Breakdown

Engineered by UM for the naked motorcycle segment, the 2018 UM Xtreet RC features a 124.2 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 13 HP (9.5 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 104.7 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 reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the Xtreet RC measures 131 kg (289 lbs) dry, translating to a power-to-weight ratio of 0.1 HP/kg (10.08 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,355 mm (53.3 in) wheelbase engineered for quick, flickable steering geometry. The 14.5-liter (3.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
