Good workmanship, terrific sound, low weight and a perfect performance characteristic, were the specifications in the development of Siebenrock SGS2 exhaust systems for the BMW R 80 G/S, R 80 / R 100 GS and the R 80 / R 100 models,. Made from polished stianless steel, the SGS2 variants give the motorbikes from Bavaria an even nobler appearance. By using a Y-pipe instead the original collector box, the sytems look very slender and sportive. because of this construction, it was possible, among other things, to reduce the weight below that in the sdandard machine by an enormous 5 kg. In the meantimean oval stainless steel silencer is responsible for the acoustics; it allows the exhaust gases to escape with a sportive and muffled sound. But that is not enough. Innumerable measurements were needed till the perfect curve on the diagrams could be obtained. It was exactly the revs mid-age that could be so improved that there was no longer any talk of dropout but one could confidently speak of a massive increase in power and torque.
The SGS2 systems are supplied with all necessary attachment parts and with EC type approval that is valid for the whole of Europe. The fitting is easily carried out thanks to very simple clamp and sprimg mountings. After the installation of the SGS2 systems in conjunction with the foot rest holder, the original luggage systems can continue to be used without restriction.
