The Akrapovic Slip-On Line is a bolt-on carbon fibre muffler for the 2021-2026 Aprilia RSV4 and Tuono V4, with a titanium link pipe and inner structure under the carbon sleeve.
The gains here are unusually strong for a slip-on: +4.9 hp at 13,000 rpm, +4.5 Nm at 7,600 rpm and 3.5 kg saved. Most slip-ons trade sound and weight for very little power; this one delivers all three because the carbon is only the outer skin — the link pipe and everything structural underneath is titanium.
Aprilia's 65-degree V4 is one of the great engines in motorcycling, and on the Tuono especially, where the canister sits exposed on a naked bike, the carbon body changes the machine's whole profile from behind.
It is EC/ECE approved, so the bike stays road legal, and needs no remapping.
Fits all variants of the 2021-2026 Aprilia RSV4 and Tuono V4, including the E5+ machines. The 2015-2020 RSV4 and Tuono take a different muffler — check your model year before ordering.
