Technical Overview
2011 TGB X Large 125 EFI Technical Analysis & Specification Breakdown
At the heart of the 2011 TGB X Large 125 EFI scooter motorcycle, TGB features a 124.6 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 12.2 HP (8.9 kW) at 8,750 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 97.9 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 X Large 125 EFI measures 174 kg (384 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (14.26 kg per horsepower). Rider ergonomics and chassis geometry center around a 790 mm (31.1 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
