DescriptionThe whole story

One thing before anything else: this silencer does not fit the F 900 GS. It fits the F 900 GS Adventure, and it fits the F 750 GS, the F 800 GS and the F 850 GS — but Akrapovic states explicitly that the standard F 900 GS is excluded. The two 900s look closely related and take different parts, and getting that wrong costs a return.

Key Features

  • 3.01 kg against the standard 4.9 kg: 1.9 kg and 38.6 per cent less
  • Twenty minutes to fit — the shortest installation of any slip-on in this range
  • Premium stainless steel construction with a lightweight titanium outer sleeve
  • Handmade carbon fibre end cap, black coating, engraved logo in an all-new relief imprint
  • Compatible with BMW's side cases, so a loaded GS stays loaded
  • 1.3 PS (1.0 kW) at 5,000 rpm and 1.1 Nm at 5,200 rpm, both low in the range
  • EC and ECE compliant, no remapping needed

Which Bikes, Precisely

BMW's middleweight GS family shares a mounting point across four models and eight years, which is unusually broad. The F 750 GS and F 850 GS run from 2018; the F 800 GS in this list is the 2023 machine, not the older bike of the same name that ended in 2018; the F 900 GS Adventure arrived in 2023.

The published figures were obtained on an F 900 GS Adventure, the largest and heaviest member of that group. On an F 750 GS the part fits identically and the weight saving is the same, because the silencer is the same object.

Twenty Minutes

Akrapovic quotes 20 minutes, and on this family that is realistic. The silencer sits exposed on the right with a single hanger and a clamp, and nothing has to come off first unless the bike is wearing its panniers. It is one of the few parts where the fitting is genuinely a driveway job.

Weight on an Adventure Bike

1.9 kg removed from high on the right-hand side improves handling on every surface, and on a GS that includes the surfaces the bike was bought for. It is also 1.9 kg less to lift when the machine is on its side in gravel — the argument that matters more than the dyno sheet on this kind of motorcycle.

Fitment and Compatibility

S-B9SO3-HFBFCTBL/1 covers the BMW F 750 GS, F 800 GS, F 850 GS and F 900 GS Adventure from model year 2018 through 2026. It does not fit the F 900 GS. If your registration document says F 900 GS without "Adventure", this is the wrong part — ask us and we will find the right one.

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.
