Engineered by Yamaha for the enduro - offroad motorcycle segment, the 2004 Yamaha WR 250 F utilizes a 249 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke layout.

With a specific output of 61 HP per liter and a 1,500 rpm working window between peak torque (6,000 rpm) and peak power (7,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
