2007 Yamaha G5 Technical Analysis & Specification Breakdown

At the heart of the 2007 Yamaha G5 sport motorcycle, Yamaha utilizes a 106 cc (6.5 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 10.2 HP (7.4 kW) at 7,850 rpm while maximum torque reaches 7.9 Nm (5.8 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 96.2 HP per liter and a 1,850 rpm working window between peak torque (6,000 rpm) and peak power (7,850 rpm), 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 G5 measures 119 kg (262 lbs) wet (curb), translating to a power-to-weight ratio of 0.09 HP/kg (11.67 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 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 13-liter (3.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
