The standard silencer weighs 5.19 kg, this one weighs 5.14 kg — fifty grams, one per cent. What it does deliver is 4 Nm at 3,650 rpm and 1.8 PS at 3,600, which on a shaft-driven tourer is the band you sit in all day.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4.0 Nm more at 3,650 rpm and 1.8 PS (1.3 kW) more at 3,600 rpm\u003c\/li\u003e\n\u003cli\u003ePeak output rises from 128.7 to 130.0 PS\u003c\/li\u003e\n\u003cli\u003ePeak torque is unchanged at 136.6 Nm — the gain is in the curve, not at its top\u003c\/li\u003e\n\u003cli\u003eTitanium muffler outer sleeve with carbon fibre parts\u003c\/li\u003e\n\u003cli\u003eCompatible with the BMW side cases, so a fully equipped RT stays equipped\u003c\/li\u003e\n\u003cli\u003eThirty minutes to fit, removable noise insert supplied\u003c\/li\u003e\n\u003cli\u003eWeight saving: 0.05 kg.

At legal speeds in sixth the ShiftCam boxer sits close to 3,500 rpm, and that is precisely where this system adds its torque.\u003c\/p\u003e\n\u003cp\u003eThe effect is in how the bike responds to the throttle without a downshift — overtaking, climbing a gradient with a full load. It is a small change in a place a tourer uses constantly, which is worth more than a larger change somewhere the bike rarely goes.\u003c\/p\u003e\n\u003ch2\u003eWhy the Weight Barely Moves\u003c\/h2\u003e\n\u003cp\u003eBMW's standard RT silencer is already a relatively light unit, and the Akrapovic replacement has to keep the same acoustic volume and the same catalytic hardware to stay within the type approval. The titanium sleeve buys back only what the shape gives up. Fifty grams is the result, and inflating it into a percentage would be a way of hiding it rather than reporting it.\u003c\/p\u003e\n\u003ch2\u003eEverything Stays Bolted On\u003c\/h2\u003e\n\u003cp\u003eThe RT is a full-dress tourer and most of them wear BMW's side cases permanently. This silencer is dimensioned around them, so nothing has to come off. The header and catalytic converter stay standard, no remapping is required, and the original unit refits in half an hour.\u003c\/p\u003e\n\u003ch2\u003eWhy We Publish the 0.05 Kilograms\u003c\/h2\u003e\n\u003cp\u003eIt would be easy to leave the weight out of this page. Every other Akrapovic listing leads with a percentage, and one per cent is not a number anyone wants to print. But an RT owner comparing exhausts deserves to know that this one is not the way to make the motorcycle lighter — there is no lighter version of this part, and a system that saved real weight would have to give up either the acoustic volume or the emissions hardware, and with it the type approval.\u003c\/p\u003e\n\u003cp\u003eWhat you are buying is the torque at 3,650 rpm, the sound of a boxer that the standard silencer holds back, and titanium and carbon in place of a painted steel box. That is a fair proposition, stated plainly.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eS-B12SO21-HALAGT covers the BMW R 1250 RT from model year 2019 through 2024.\u003c\/p\u003e\n\u003ch2\u003eRoad Approval\u003c\/h2\u003e\n\u003cp\u003eEC type approval and ECE type approval, with the certificates supplied and downloadable here.
