Technical Overview
2011 Yamaha Grand Axis 100 Technical Analysis & Specification Breakdown
At the heart of the 2011 Yamaha Grand Axis 100 scooter motorcycle, Yamaha utilizes a 101 cc (6.2 cu in) air-cooled single cylinder, two-stroke layout. In factory specification, peak output is rated at 9.9 HP (7.2 kW) at 7,000 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 98 HP per liter, 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 Grand Axis 100 measures 93 kg (205 lbs) dry, translating to a power-to-weight ratio of 0.11 HP/kg (9.39 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 1,275 mm (50.2 in) wheelbase engineered for quick, flickable steering geometry. The 6.5-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
