Akrapovic Slip-On Line Carbon Aprilia RSV4 / RSV4 RR / RSV4 1100 Factory (2021-2026) S-A10SO13-RC

The Akrapovic Slip-On Line in full carbon dress is one of the most visually striking and immediately rewarding upgrades available for the Aprilia RSV4, RSV4 RR and RSV4 1100 Factory. Shaped by decades of Grand Prix development, the hexagonal carbon silencer with its matching carbon end-cap carries the unmistakeable Akrapovic racing aesthetic — a heritage you can see before you even hear the exhaust note.

Key Features

• Substantial weight saving of 3.5 kg over the standard system (stock 5.7 kg reduced to 2.1 kg) for a leaner, sharper-feeling machine
• Power output rises by 4.9 hp to 207.6 hp at 13,450 rpm, with torque up by 4.5 Nm at 7,600 rpm
• Sound level increases by 10.8 dB, delivering 106.8 dB at 5,500 rpm — the signature Akrapovic racing note, unfiltered
• Hexagonal silencer housing in woven carbon fibre with a carbon end-cap; all metallic internals, including the baffle, are titanium
• Titanium link pipe connects directly to the original header, making installation straightforward with no modification to the stock exhaust manifold
• dB-Eater included for situations where reduced noise output is required on a closed circuit
• Optional carbon exhaust bracket available when the pillion footpegs are removed — select at checkout

Design, Finish and Heritage

Akrapovic's Slip-On Line sits at the intersection of race-bred engineering and industrial craftsmanship. The natural carbon weave on the silencer shell and end-cap is not a cosmetic overlay — it is structural, contributing directly to the weight figure that makes this system so significant in the hand and on the scales. The hexagonal silencer profile is a design signature developed on World Superbike machinery and carried through to every carbon Slip-On that leaves the Akrapovic factory in Slovenia.

Titanium was chosen for every internal and metallic component because it offers an unmatched combination of strength, heat resistance and low mass. The result is a silencer that runs cooler-looking and cooler-running than comparable stainless systems, with a surface finish that ages with character rather than corroding.

Performance in Context

A gain of 4.9 hp and 4.5 Nm of torque from a slip-on is a genuinely meaningful result on a motorcycle already producing over 200 hp. The improvement is spread across the rev range, with the torque peak arriving at 7,600 rpm — well within everyday riding territory on the RSV4 — making the engine feel more responsive on circuit exit and out of slower corners on the road. The 3.5 kg reduction in unsprung and rotating mass amplifies these gains in handling terms beyond what the raw power figures alone suggest.

Track Use and Legal Notice

The Akrapovic Slip-On Line (Carbon) S-A10SO13-RC is designed exclusively for closed-circuit competition use. It does not carry road-use type approval and must not be fitted to motorcycles used on public roads. Fitting a dB-Eater (included) does not confer road legality.

Fitment and Compatibility

• Aprilia RSV4 (2021-2026)
• Aprilia RSV4 RR (2021-2026)
• Aprilia RSV4 1100 Factory (2021-2026)

Connects to the original exhaust header — no manifold replacement required. When removing the pillion footpegs, the optional carbon exhaust bracket (available as a variant) is recommended to support the silencer correctly.
