This 450cc motocross nameplate arrived for the 2005 model year as Suzuki’s first twin-beam aluminum-framed motocross bike and the company’s first 4-stroke, liquid-cooled, single-cylinder DOHC 4-valve race machine. It was conceived as a light, compact, open-class motocrosser that blended a broad four-stroke power delivery with the sharp handling expected from a factory-style competition bike. A significant full model change followed for the 2008 model year, bringing fuel injection, a five-speed transmission, and a newly designed aluminum frame, marking a major step in the bike’s evolution rather than a separate revival.
From there, the nameplate continued as a core Suzuki motocross offering through later updates and refreshes, including more modern chassis, suspension, and electronic launch-assist developments in the 2010s and beyond. The model has remained in the brand’s global motocross lineup through the 2027 model year, reflecting its long-running position as Suzuki’s flagship 450cc closed-course racer. Because production continues, there is no final year to report. The nameplate has not been discontinued and revived as a separate run; instead, it has evolved continuously since its debut.
