High-quality decompressor spring suitable for your Piaggio Si moped / moped.
The decompressor spring impresses with its dimensional accuracy, which ensures that both the distance in the relaxed state and the pressure point at which the valve is to open correspond to the original when fitted. This avoids problems with unsuitable cable lengths with pre-assembled deco cables.
You can find more parts for your decompression valve in the accessories section.
Nostalgic product for the highest demands of the quality brand swiing®.
