Bigger tank, longer travel, a different subframe and a different exhaust route — and this is the part number that fits it.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBuilt specifically for the Adventure Sports, not the standard Africa Twin\u003c\/li\u003e\n\u003cli\u003eCovers seven model years, 2020 through 2026, on one number\u003c\/li\u003e\n\u003cli\u003e2.4 kg, taking 2.3 kg off the standard assembly\u003c\/li\u003e\n\u003cli\u003eFinished stainless steel\u003c\/li\u003e\n\u003cli\u003eWorks with either Akrapovic Slip-On Line for this machine\u003c\/li\u003e\n\u003cli\u003eCompatible with Honda's centre stand and front side pipe kit\u003c\/li\u003e\n\u003cli\u003eClosed course competition use only\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy the Adventure Sports Needs Its Own Number\u003c\/h2\u003e\n\u003cp\u003eThe two Africa Twins share an engine and very little else around it. The Adventure Sports carries a 24.8 litre tank against 18.8, a taller subframe, and on most versions the electronic suspension. Where the header runs between the cylinder head and the swingarm pivot is not the same on the two bikes.\u003c\/p\u003e\n\u003cp\u003eFitting the standard bike's E-H11R1 to an Adventure Sports is not a matter of persuasion. It is the wrong part.\u003c\/p\u003e\n\u003ch2\u003eTwo Hundred and Eighty Grams Apart\u003c\/h2\u003e\n\u003cp\u003eThis header comes in at 2.4 kg. The one for the standard machine reaches 2.12. Both start from the same 4.7 kg factory assembly, and the difference between them is pipework length: the Adventure Sports simply needs more steel to cover the distance.\u003c\/p\u003e\n\u003cp\u003eNobody will feel 280 grams. It is quoted because the two part numbers sit next to each other in the catalogue and the figures differ, which invites the question.\u003c\/p\u003e\n\u003ch2\u003eSeven Model Years\u003c\/h2\u003e\n\u003cp\u003eHonda has built the CRF1100L Adventure Sports since 2020 without changing the exhaust route, so one header covers the whole run to date. That is unusually broad coverage for a part in this catalogue and it makes the Adventure Sports a straightforward bike to buy for.\u003c\/p\u003e\n\u003ch2\u003eThe Noise Data Contradicts Itself\u003c\/h2\u003e\n\u003cp\u003eAkrapovic's record for this part lists 99.7 dB for the standard exhaust and 95 dB with the header fitted, both at 3,750 rpm — that is, quieter after removing the catalytic converter, which is not physically plausible.\u003c\/p\u003e\n\u003cp\u003eThe entry for the standard bike's header, E-H11R1, gives the same two numbers the other way round: 95 dB standard, 99.7 with the part fitted. That is almost certainly the correct reading and this one has its fields transposed. Expect the Adventure Sports to get louder, not quieter, and treat the exact figure as unverified.\u003c\/p\u003e\n\u003ch2\u003eBoth Slip-Ons Fit\u003c\/h2\u003e\n\u003cp\u003eAkrapovic notes that this header combines with either Slip-On Line exhaust for the Adventure Sports — the earlier S-H11SO2-HGJT and the current S-H11SO4-HAFT. That is useful for an owner who fitted a slip-on years ago and is only now adding the header.\u003c\/p\u003e\n\u003ch2\u003eTouring Hardware Survives\u003c\/h2\u003e\n\u003cp\u003eThe centre stand and Honda's front side pipe kit both remain usable. On a motorcycle bought for long distances, that is not a detail — it is the difference between a part that suits the bike and one that fights it.\u003c\/p\u003e\n\u003ch2\u003eRemapping and the Check Light\u003c\/h2\u003e\n\u003cp\u003eAkrapovic recommends rather than requires ECU remapping. On Euro 5+ machines the engine check light will come on once the ECU notices the catalytic converter is gone, which is expected rather than faulty.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eNone whatsoever. Akrapovic marks the part as failing emission compliance for street and highway riding, and the missing catalytic converter is the reason.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: E-H11R2\u003c\/li\u003e\n\u003cli\u003eEAN: 3831126433895\u003c\/li\u003e\n\u003cli\u003eFits: the Honda CRF1100L Adventure Sports, model years 2020 through 2026\u003c\/li\u003e\n\u003cli\u003eCategory: header, sold to complete an Akrapovic slip-on installation\u003c\/li\u003e\n\u003cli\u003eMaterial: stainless steel, finished\u003c\/li\u003e\n\u003cli\u003eWeight fitted: 2.4 kg; factory assembly 4.7 kg\u003c\/li\u003e\n\u003cli\u003ePeak power: 101.7 PS where the factory reads 92.6, the 8.9 PS increase falling at 7,500 rpm\u003c\/li\u003e\n\u003cli\u003ePeak torque: 108.3 Nm where the factory reads 102.6, with 6.2 Nm more arriving at 6,000 rpm\u003c\/li\u003e\n\u003cli\u003eNoise: the manufacturer's two readings are transposed, as set out above\u003c\/li\u003e\n\u003cli\u003eTouring hardware: centre stand and Honda front side pipe kit both retained\u003c\/li\u003e\n\u003cli\u003eFitting: roughly sixty minutes\u003c\/li\u003e\n\u003cli\u003eHomologation: none, circuits only\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Akrapovic","offers":[{"title":"Default Title","offer_id":53628952510730,"sku":"E-H11R2","price":19814.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/01_4335659c-132b-41dd-8bd6-88f2f7348747.png?v=1788554859","url":"https:\/\/inter-pace.com\/en-tw\/products\/akrapovic-optional-header-stainless-honda-africa-twin-adventure-sports-e-h11r2","provider":"Inter-Pace","version":"1.0","type":"link"}
