Engineered by TGB for the scooter motorcycle segment, the 2008 TGB 303RS 125 pairs a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 8.6 HP (6.3 kW). 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 303RS 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 6.8-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
