This is a left-hand-side only blanking plate for the passenger footpeg on Aprilia RSV4 (all models) '09-, Tuono V4 (all models) '11-, RS660 '21- Tuono 660 '21- & Tuono V4 1100 '21-.

If you don't take passengers, or you have a track bike, these blanking plates finish the tail off nicely. Cover the bolt holes left when foot pegs are removed and stop debris build up from getting in the threads. Easy to fit and really tidy up the sub frame.
