I am a Mana newbee, just bought it a month ago. I believe this is the most informative Aprilia forum in the world, so I am here.

I've got the question about a conveyor cover on the left side of the bike.

There is something like foam rubber glued from the inside of this cover. Does this coating have any significance besides vibration and noise protection?

On my bike, this foam rubber falls off in pieces so I think of just removing it. Or maybe stick something instead?
