DescriptionThe whole story

Two hundred and five horsepower, and it is road legal. Aprilia's V4 is one of the most powerful engines in production motorcycling, and this slip-on takes it to 205.5 PS while keeping both EC and ECE type approval.

Key Features

  • EC and ECE type approved
  • Reaches 205.5 PS from a standard 203.4, with 2.9 PS more at 12,500 rpm
  • Torque up by 1.6 Nm at 10,000 rpm
  • 3.3 kg fitted against 5.1 kg standard — 1.8 kg saved
  • Handmade carbon fibre heat shield included
  • Sandblasted coated finish for durability and easier cleaning
  • Inspired by Superbike Championship exhaust systems

Coated, Not Bare

Akrapovic gives the titanium a sandblasted coated finish rather than leaving it polished. The stated reasons are durability and easier cleaning, and both are practical on a bike ridden hard: bare titanium picks up heat colours and holds road film in a way a coated matt surface does not.

The Heat Shield Is in the Box

A handmade carbon fibre heat shield comes with the exhaust. On most slip-ons in this catalogue that is a separate purchase, and on a system at this price it should not be — Akrapovic agrees.

Four Motorcycles

Aprilia's 1099 cc V4 powers the faired RSV4 and RSV4 Factory and the naked Tuono V4 and Tuono V4 Factory. All four take this silencer for 2025 and 2026.

The Factory versions carry Öhlins electronic suspension and forged wheels; mechanically the exhaust mounting is identical.

Where the Gains Sit

2.9 PS at 12,500 rpm and 1.6 Nm at 10,000. Both are near the top of the range, which is where a V4 superbike is worked on a circuit — and on a 203 PS engine, gains of that size from an approved slip-on are respectable.

Akrapovic measured them on an RSV4 with the standard exhaust on its own dyno.

An Hour

Sixty minutes for a slip-on is longer than usual, and the reason is the RSV4's packaging: the silencer sits under the tail behind bodywork that has to come off first. Not difficult, just not a five-minute change.

Inspired by the Championship

Akrapovic builds the exhausts for Aprilia's World Superbike effort, and it says this system draws on that work. On a road part that claim is usually decoration; here the same company makes both, and the shapes are visibly related.

Easier to Clean

Akrapovic names cleaning as a reason for the coated finish, which is a practical detail rather than a marketing one. A polished titanium can on a bike ridden in the rain needs work to keep looking right; a sandblasted coated one wipes down.

Road Approval

EC and ECE type approval are both in place. No entry in the vehicle documents is required.
