CygnusX

2008 Yamaha CygnusX Technical Analysis & Specification Breakdown

Engineered by Yamaha for the scooter motorcycle segment, the 2008 Yamaha CygnusX pairs a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 10.7 HP (7.8 kW) at 8,500 rpm while maximum torque reaches 9.3 Nm (6.9 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox. With a specific output of 85.6 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 CygnusX measures 116 kg (256 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.84 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,295 mm (51 in) wheelbase engineered for quick, flickable steering geometry. The 7.1-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
