• Piaggio spare parts vary between versions and markets for the same model. If in doubt, send us the chassis number and we will verify the code in the official catalog before shipping.
• This item is only the soundproofing cover: the transmission cover (B0159005) and fasteners are separate parts.
• Installation requires access to the transmission compartment: if you are not familiar with it, have it done at a workshop.

Who it's perfect for
It is useful for those who have disassembled the transmission of their Piaggio 350 – belt, rollers, clutch replacement – and find the soundproofing damaged, detached or missing, and for those who notice an increase in noise from the left side of the engine. This is a part that degrades with heat and over the years. As it is an original Piaggio part, there are no surprises regarding fit: the shape is the standard one.
