Since the beginning, the GSX-R750 has been all about the overall balance of handling and engine performance.
For 2004, the GSX-R750 takes that balance to an entirely new level. In a compact, lightweight design producing a breakthtaking combination of handling and sheer engine performance.
Packed with genuine Suzuki technology and wrapped in bodywork that not only delivers an exciting, distinctive new look, but also improves aerodynamics and the efficiency of the ram-air intake system. A narrower, edgy fairing with less weight and a smaller frontal area. Dual vertically-stacked headlights and relocated ram-air intakes. Combined with a black frame and swingarm, radial-mount front brakes, a slash-cut muffler tip and a compact, lightweight LED taillight.

Leading the class is one thing. Leaving it far behind is another.
The 2004 Suzuki GSX-R600 really is in a class of its own. With the most torque, the lowest dry weight and the best power-to-weight ratio.
 
Designed with better aerodynamics. A more effective ram-air intake system. Stronger brakes. More linear torque delivery. Better acceleration.
 
The goal is winning. The plan, overwhelm the would-be competition and establish domination.
In other words, the Suzuki GSX-R600 is a 600 like no other.
