Performance

The 2.60 kg weight of the Arrow system corresponds to the weight of this exhaust, which is the only one available for the motorcycle.

Who is it perfect for?

For anyone with a BMW F 800 R from 2009 to 2016 who wants to remove the stock silencer without replacing the exhaust system or compromising legality. The dark body with the carbon fibre end cap looks great on the naked bike, the adapter and db-killer are already included in the package, and the motorcycle loses 2.3 kg on the right side. However, anyone who travels with the original BMW panniers should know that this exhaust is not compatible with them.
