2004 | GSX400 IMPULSE

Sporty street bike that continues the Impulse legend


The GSX400 IMPULSE has a distinctive and memorable naked styling that amply expresses the simple essence of motorcycles. It features a 400 cm³ liquid-cooled 4-cylinder DOHC engine with powerful acceleration and tenacious performance at low to middle revs. Other features include a highly functional analog 2-dial instrument cluster and a 4-into-1 muffler with a large, aggressively styled aluminum silencer, which help to raise the refinement and presence of the GSX400 IMPULSE to the next level as a sporty street bike. The front brakes also feature high-performance 4-pot calipers with opposed pistons.
