DescriptionThe whole story▼
4.2 newton metres at 4,800 rpm on a water-cooled boxer. That is where a loaded GS pulls in top gear on a country road, and it is the figure that justifies a header on a motorcycle nobody buys for its top end.
Key Features
- 1.8 kg against the standard 4.0 kg: 2.2 kg and 55 per cent less
- 4.2 Nm more at 4,800 rpm and 3.5 PS at 7,300 rpm
- Made from the finest titanium
- Turns an Akrapovic slip-on into a full system
- Covers both the GS and the GS Adventure
- No road approval — circuit use only
The First Water-Cooled Generation
BMW moved the GS to partial water cooling in 2013 and revised it again in 2019 with the ShiftCam 1250. This header belongs to the years in between — the machines that made the modern GS what it is, and which are used motorcycles today.
That has a practical consequence. On a bike out of warranty and past its resale peak, a track-only header is a more defensible purchase than it would be on a new machine, and a titanium part will outlast whatever else the motorcycle needs.
Nearly Two Hours
Akrapovic quotes 105 minutes. A boxer's exhaust ports are accessible, but the header runs under the engine and the sump guard has to come off first — and on a GS Adventure with full crash protection there is more hardware in the way than on a base bike.
Plan a workshop session with the motorcycle on a lift rather than an evening in the garage.
What You Need Alongside It
This header does not work on its own. It requires an Akrapovic slip-on — for these machines that is S-B12SO10-HAABL for the 2013 to 2016 bikes and S-B12SO16-HAABL for 2017 and 2018. Both are type approved on their own; adding this header ends that approval.
The Adventure Carries More Around It
A GS Adventure weighs roughly ten kilograms more than a base GS before any luggage goes on, and much of that difference is bodywork, tank capacity and protection sitting exactly where a mechanic needs to reach. The header is the same part for both machines; the labour is not.
If your Adventure runs engine bars, a larger sump guard or auxiliary lights on the crash frame, budget beyond Akrapovic's 105 minutes.
Not the 1250
BMW replaced this engine in 2019 with the ShiftCam 1250, which uses a different exhaust layout. E-B12E1 does not fit an R 1250 — that machine takes E-B12E4/1, which is a separate part with an exhaust valve.
Fitment and Compatibility
E-B12E1 covers the BMW R 1200 GS from model year 2013 through 2018 and the GS Adventure from 2014 through 2018.
Road Approval
None. This product does not meet emission compliance requirements for street or highway use.
