Introduced for the 2004 model year, this motocross nameplate marked Suzuki’s first four-stroke motocrosser and arrived as a purpose-built 250cc race machine. Its debut established the formula that would define the model: a lightweight, competition-focused chassis, a liquid-cooled four-stroke single, and a clear emphasis on rider mobility and track performance. The early bike quickly became an important step in Suzuki’s off-road lineup because it shifted the brand’s quarter-liter motocross effort from two-stroke tradition into the modern four-stroke era.
The model was substantially reworked for 2007, when Suzuki brought in a new engine and a new twin-beam aluminum frame to sharpen handling and broaden the power delivery. Another major milestone came in 2010, when fuel injection replaced the earlier carbureted setup, improving throttle response and startability while keeping the bike firmly aimed at serious motocross use. In 2019, Suzuki gave the machine another major update with a new frame, swingarm, revised bodywork, and a twin-injector fuel-injection system, reinforcing the model’s focus on easier tuning, stronger low-end response, and more precise chassis behavior.
Rather than being a one-off special, the nameplate has remained a continuing part of Suzuki’s competition line for decades, evolving through repeated technical updates while preserving its core identity as the brand’s dedicated 250cc motocross racer.
