Technical Overview
2021 Um Flash 110 Technical Analysis & Specification Breakdown
At the heart of the 2021 Um Flash 110 scooter motorcycle, Um pairs a 110 cc (6.7 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 6.8 HP (5 kW) at 8,000 rpm while maximum torque reaches 7 Nm (5.2 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a automatic gearbox and chain final drive. With a specific output of 61.8 HP per liter and a 1,500 rpm working window between peak torque (6,500 rpm) and peak power (8,000 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 Flash 110 measures 91 kg (201 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (13.38 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,250 mm (49.2 in) wheelbase engineered for quick, flickable steering geometry.
