Technical Overview
2009 Giantco Cyrus II 125 Technical Analysis & Specification Breakdown
At the heart of the 2009 Giantco Cyrus II 125 scooter motorcycle, Giantco pairs a 124.6 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 7.2 HP (5.3 kW) at 7,500 rpm while maximum torque reaches 7 Nm (5.2 lb-ft) at 6,000 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 57.8 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 rpm), the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the Cyrus II 125 measures 112 kg (247 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.56 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 6-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
