Who it is perfect for
It is intended for those who have disassembled the transmission of their 350 Piaggio – for a belt, roller, or clutch change – and find the soundproofing damaged, unglued, or missing, or for those who notice an increase in noise from the left side of the engine. It is a part that degrades with heat and over time. Being the original Piaggio part, there are no fitment surprises: the shape is identical to the factory original.
