BOS Carbon-Steel Yamaha TRX 850, E-approved, slip-in, round
Modern technologies and the use of only absolutely high-quality materials have made BOS one of the leading exhaust brands in Germany and even in Europe.
The muffled, pithy and very adult sound is the distinguishing feature of BOS. The silencer sounds more present and powerful than the original.
Each rear silencer is specially homologated for the respective model.
BOS dampers are smaller and lighter than the original dampers.
The performance and the torque curve are optimized.
Because BOS only uses high quality materials, a long life is guaranteed.
The BOS dampers are attached to the motorcycle with a bracket instead of the often unattractive clamp. This not only looks better, but also gives a better hold, the finish is convincing.
