At the heart of the 2011 Suzuki Grasstracker Bigboy allround motorcycle, Suzuki features a 249 cc (15.2 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 18.8 HP (13.7 kW) at 7,500 rpm while maximum torque reaches 21 Nm (15.5 lb-ft) at 5,500 rpm, transferring power to the rear wheel through a 5-speed gearbox. With a specific output of 75.5 HP per liter and a 2,000 rpm working window between peak torque (5,500 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.
