DescriptionThe whole story

One thing before the numbers: this silencer carries an EC type approval and no ECE certificate. Most parts in this catalogue have both; this one does not, and Akrapovic's own homologation entry confirms it. For a motorcycle registered in the EU the EC document is the relevant one.

Key Features

  • 4.7 Nm more at 4,900 rpm and 1.8 PS at 4,550 rpm — both low in the range
  • 4.3 kg against the standard 5.0 kg: 0.7 kg and 14 per cent less
  • Titanium muffler outer sleeve, black finish
  • Removable noise insert supplied
  • Fits both the R 1200 GS and the GS Adventure
  • EC type approval — no ECE

The First Water-Cooled Boxer

BMW switched the GS to partial water cooling in 2013, and the 2013 to 2016 machines are that first generation — before the 2017 revision and long before ShiftCam arrived with the 1250. The exhaust route belongs to that generation alone, and later parts do not fit.

These are used motorcycles today and they are the ones that made the GS what it is. A titanium silencer on a well-kept example is a long-term fitting: the standard unit is a steel assembly that corrodes at the seam with age, and this replacement will outlast the rest of the bike.

Torque at Touring Speed

4.7 Nm at 4,900 rpm is where a loaded GS pulls on a country road in top gear. That is the useful figure, and it is unusually large for a slip-on on a 125 PS boxer.

The 14 per cent weight saving is real but secondary. BMW's standard silencer here is a substantial piece, and 0.7 kg comes off the high right-hand side — where an adventure bike notices it when it has to be picked up.

GS and GS Adventure

The Adventure carries a 30-litre tank, wider crash bars and more suspension travel, but the engine, the frame and the exhaust mounting are shared. One silencer fits both. On an Adventure wearing factory panniers, plan on removing the right-hand rail before the mounting is reachable.

What Stays Standard

The header, the catalytic converter and the engine management are untouched, and no remapping is required. The original silencer bolts back on if the GS is sold in factory condition.

The removable noise insert is supplied, so the tone can be kept close to standard for an inspection or opened up with a single bolt — which on a bike of this age is the difference between a straightforward MOT and a conversation.

Fitment and Compatibility

S-B12SO10-HAABL covers the BMW R 1200 GS from model year 2013 through 2016 and the GS Adventure from 2014 through 2016. For the 2017 and 2018 machines the corresponding part is S-B12SO16-HAABL.

Road Approval

EC type approval, with the certificate supplied and downloadable here. There is no ECE certificate for this part. The silencer is a legal replacement part for road use in the European Union.
