SGS2-2M Dual 1811009 - R100 GS - Two person version (with passenger) Medium Position
Excellent workmanship, terrific sound, low weight and a perfect performance characteristic, were the specifications in the development of Siebenrock SGS2 exhaust systems for the R80G/S, R80/100GS and the R80/100R models.
Made from polished stainless steel, the SGS2 variants give the motorbikes from Bavaria an even nobler appearance. By using a Y-pipe instead of the original collector box, the systems look very slender and sporty. Because of this construction, it was possible, among other things, to reduce the weight by an enormous 5 kg. ( 11 Lbs.) In the meantime an oval stainless steel silencer is responsible for the acoustics; it allows the exhaust gases to escape with a sporty and muffled sound.
But that is not enough: Innumerable measurements were needed until the perfect curve on the Dyno charts could be obtained. It was precisely the mid-range that could be greatly improved with all surges eliminated and with a massive increase in power and torque.
The SGS2 systems are supplied with all necessary attachment parts and an ABE that is valid for the whole of Europe. The fitting is easily carried out thanks to very simple clamp and spring mountings. The use of the SGS2 systems in no way restricts the mounting of the original luggage systems.
