Built around TGB's scooter motorcycle platform, the 2008 TGB 101R 125 relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 8.6 HP (6.3 kW) at 7,500 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 69.4 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the 101R 125 measures 110 kg (243 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.79 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 5.1-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
