At the heart of the 2010 Kymco KR Sport 125 sport motorcycle, Kymco relies on a 124.1 cc (7.6 cu in) air-cooled in-line six, four-stroke powerplant. In factory specification, peak output is rated at 12.9 HP (9.4 kW) at 10,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 103.9 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.

Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance.
