This time some pics of a very trick RG500, this bike is based on the Suzuki RG500 Gamma street bike but is heavily modified by the German RG500 specialist STR, this bike has just over 130 hp. Take a look at the frame with the delta box like beams and modified swing arm. Other striking thing is that German RG500's often make use of the standard airbox with good succes. In other parts of the world this box ends in most cases in the bin. These kind of bikes are ridden in the German IG Königsklasse.
