Built around Sym's scooter motorcycle platform, the 2011 Sym Citycom 125i pairs a 124.5 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 20.7 HP (15.1 kW) at 7,000 rpm while maximum torque reaches 23.5 Nm (17.3 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 166.3 HP per liter and a 1,500 rpm working window between peak torque (5,500 rpm) and peak power (7,000 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Citycom 125i measures 190 kg (419 lbs) wet (curb), translating to a power-to-weight ratio of 0.11 HP/kg (9.18 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 1,500 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 10-liter (2.6 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 128 km/h (80 mph).
