This header belongs to the years in between — the machines that made the modern GS what it is, and which are used motorcycles today.\u003c\/p\u003e\n\u003cp\u003eThat 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.\u003c\/p\u003e\n\u003ch2\u003eNearly Two Hours\u003c\/h2\u003e\n\u003cp\u003eAkrapovic 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.\u003c\/p\u003e\n\u003cp\u003ePlan a workshop session with the motorcycle on a lift rather than an evening in the garage.\u003c\/p\u003e\n\u003ch2\u003eWhat You Need Alongside It\u003c\/h2\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch2\u003eThe Adventure Carries More Around It\u003c\/h2\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eIf your Adventure runs engine bars, a larger sump guard or auxiliary lights on the crash frame, budget beyond Akrapovic's 105 minutes.\u003c\/p\u003e\n\u003ch2\u003eNot the 1250\u003c\/h2\u003e\n\u003cp\u003eBMW replaced this engine in 2019 with the ShiftCam 1250, which uses a different exhaust layout.
