A POWERFUL DESIGN. Suzuki has once again reinvented the category again with the DF75A. Suzuki’s new generation of four-strokes, the DF75A is a showcase of advancements and achievements – like digital sequential electronic fuel injection, a powerful 2.59:1 final drive ratio, and a zero-maintenance self-adjusting time chain. All of this comes in addition to Suzuki’s Lean Burn Control System, and newer models also sport the optional Suzuki Troll Mode System.
