Technical Overview
2021 Um Xtreet 230 R Technical Analysis & Specification Breakdown
Built around Um's naked motorcycle platform, the 2021 Um Xtreet 230 R pairs a 221 cc (13.5 cu in) oil & air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 17.3 HP (12.6 kW) at 8,200 rpm while maximum torque reaches 16.5 Nm (12.2 lb-ft) at 4,600 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 78.3 HP per liter and a 3,600 rpm working window between peak torque (4,600 rpm) and peak power (8,200 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 230 R measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.14 HP/kg (6.94 kg per horsepower). Rider ergonomics and chassis geometry center around a 806 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry.
