Technical Overview
2008 UM Xpeed 250i Technical Analysis & Specification Breakdown
Built around UM's scooter motorcycle platform, the 2008 UM Xpeed 250i relies on a 249 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 24 HP (17.5 kW) at 9,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 96.4 HP per liter, 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 Xpeed 250i measures 164.7 kg (363 lbs) dry, translating to a power-to-weight ratio of 0.15 HP/kg (6.86 kg per horsepower). Rider ergonomics and chassis geometry center around a 759 mm (29.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops. The 10.97-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
