Matched to the 2025 Bike
Aprilia changed this plumbing with the Euro 5+ update, so the earlier kit no longer fits. This part number is specific to the current motorcycle.
Emissions Hardware Grew
Each tightening of the standard adds components rather than removing them. The area behind the engine is more crowded on the current bike than it was on the first.
Visible From Beside the Bike
With no bodywork there, a vessel and three hoses are the first thing anyone notices. On a naked motorcycle that is a real objection as well as a practical one.
Vented Properly
The tank breathes through a correct fitting rather than an open pipe, which matters the first time the bike travels on its side.
The Monitored Valve
The purge solenoid is checked electrically. The circuit is closed correctly so nothing is stored and the panel stays clear.
Ninety-Five Horsepower
Softened slightly from the RS 660 tune to suit the wide bars. Aprilia kept the figure through the emissions update, which was not a given.
Space Recovered
Shock, linkage and exhaust hanger all become reachable without removing anything else.
A Real Pillion Seat
Unusually for the class, someone can sit on the back for an hour without complaining. Aprilia treated the Tuono as a road bike first.
Reversible
Original bracket, original hoses, nothing cut anywhere.
Type Approval
Removing evaporative control ends road legality across Europe.
Ninety-Five Horsepower Through Euro 5+
Aprilia kept the figure through the emissions update, which was not a given and cost real engineering effort. The hardware that made it possible is exactly what a track-only motorcycle has no use for.
