Built around TGB's scooter motorcycle platform, the 2008 TGB X motion 250 EFI pairs a 251 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 21.4 HP (15.6 kW) at 7,750 rpm, transferring power to the rear wheel through a automatic gearbox and belt final drive. With a specific output of 85.3 HP per liter, the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
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.
