The GSX1400 is a big naked bike equipped with a newly developed oil-cooled 1,400 cm³ engine, the highest displacement of any 4-cylinder motorcycle engine produced by Suzuki. Incorporating a number of incremental advances, this oil-cooled in-line 4-cylinder DOHC 4-valve engine generates maximum output of 74 kW (100 PS) and maximum torque of 126 N·m. The first fuel injection system for an oil-cooled engine was developed and adopted for greater startability, stability, and fuel economy. The engine is paired with a 6-speed transmission that delivers sporty riding performance and comfort for long-distance cruising. Befitting its role as Suzuki’s flagship model, the styling is dignified and imposing while evoking the agility of a naked bike design.
