Our RAPID GAS socket-joint is used only for some models of motorbike ... It is very important to check that your gas has the shells separated by the instrumentation and they have to be made of alluminium . In addition they must have a double bend( like a banana) ... All the other shells , contained in the instrumentation , in plastic or iron maden for the cables exit ARE NOT SIUTABLE with our socket-joint.... You have not to change the cables it is enough to adjust them according to the standard measures that are alredy available along the shells of the original cables. They shorten the stroke by 58°but you have to check the original gas stroke that overcomes 65°and sometime it will reach 90° ... The gas colour you are going to get can be different each time according to the one available . It is not possible to choose the colour but this is not important as it is hidden after the assemblage ...
