The Akrapovic Slip-On Line is a bolt-on carbon fibre muffler for the 2015-2024 Aprilia RSV4 RR, RSV4 RF and Tuono V4 1100 RR and Factory.
Aprilia's 65-degree V4 is one of the best-sounding engines in production motorcycling, and the slip-on is the shortest route to hearing it properly. On the Tuono in particular, where the canister sits fully exposed on a naked bike, the carbon body also changes how the machine looks from behind.
A slip-on will not reach the catalyst — that lives in the mid-section on these bikes — so this is the sound-and-weight upgrade rather than the full-power one. That is the honest trade: it keeps the bike's fuelling and behaviour unchanged, needs no remap, and costs a fraction of a complete system.
Fits the 2015-2024 Aprilia RSV4 RR, RSV4 RF, Tuono V4 1100 RR and Tuono V4 1100 Factory. Check your local sound and emissions requirements before fitting.
