Built around Yamaha's naked motorcycle platform, the 2009 Yamaha YBR250 features a 249 cc (15.2 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 21.1 HP (15.4 kW) while maximum torque reaches 20.7 Nm (15.3 lb-ft) at 2,100 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 84.7 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 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,360 mm (53.5 in) wheelbase engineered for quick, flickable steering geometry. The 19-liter (5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
