DescriptionThe whole story▼
This silencer does not work on its own. It needs a link pipe, and there are four to choose from — the choice decides whether the exhaust sits high or low on the bike, and it depends on your model year. Getting this wrong means the parcel arrives and the motorcycle stays on the stand, so read the next section before ordering.
Key Features
- Black-coated titanium muffler outer sleeve with carbon fibre parts
- Fits the whole R nineT family: the base bike from 2014, and Pure, Racer, Scrambler and Urban G/S from 2017
- Two mounting positions, high or low, decided by which link pipe you order
- EC and ECE type approved
- Akrapovic publishes no measured weight or power figures for this system — none are claimed here
Which Link Pipe You Need
Four options, by mounting position and model year:
- Low mount, 2014–2020: L-B12SO8T
- Low mount, 2021–2023: L-B12SO10
- High mount, 2014–2020: L-B12SO9T
- High mount, 2021–2023: L-B12SO11
Two further conditions come from BMW's own hardware. If your R nineT left the factory with the high-mounted dual-flow silencer and you want the low position, the pillion passenger frame has to come off, and you need BMW's aluminium muffler holder, part number 77 11 8 564 071. BMW's covers for the main frame's threaded fasteners, 77 25 8 536 857, are worth adding — without them the exposed screw connections on the frame look unfinished.
If you choose a high-mount link pipe, the passenger footpegs have to be removed.
No Numbers, and Why We Say So
For most systems in this catalogue Akrapovic publishes a dyno sheet and a weight. For this one it does not. Rather than estimate from a comparable part or quote the brochure language, this page states the absence: there is no measured weight saving and no measured power gain to report.
What is documented is the construction, the finish and the approval. Buy it for the way it looks and sounds on an R nineT and for the type approval that comes with it, not for a performance figure nobody has published.
One Silencer, Six Motorcycles
BMW built the R nineT family around one air- and oil-cooled boxer with different bodywork, wheels and riding positions: the original roadster, the stripped-back Pure, the café-racer Racer, the block-tyred Scrambler and the Urban G/S in its Dakar colours. The exhaust mounting is shared, which is why one part number covers all of them — the link pipe is what adapts it to your bike.
Fitment and Compatibility
S-B12SO17-HBRBL covers the BMW R nineT from model year 2014 through 2023, and the Pure, Racer, Scrambler and Urban G/S from 2017 through 2023. For the R 12 nineT from 2024 the corresponding part is S-B12SO25-HISSSBL.
Road Approval
EC type approval and ECE type approval, with the certificates supplied and downloadable here. The silencer is a legal replacement part for road use in the European Union.
