Engineered by Yamaha for the sport motorcycle segment, the 2007 Yamaha Crux features a 105.6 cc (6.4 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 7.6 HP (5.5 kW) at 7,500 rpm while maximum torque reaches 7.5 Nm (5.5 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 72 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.
