At the heart of the 2011 K2O Cento 25 scooter motorcycle, K2O utilizes a 124.6 cc (7.6 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 12.1 HP (8.8 kW) while maximum torque reaches 10.5 Nm (7.7 lb-ft), transferring power to the rear wheel through a automatic gearbox. With a specific output of 97.1 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.
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 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
