Decompression valve suitable for Malossi cylinder heads on your Piaggio Ciao, Si, Bravo and Boxer moped / moped.
This decompression valve was originally installed on the BIG DEPS cylinder head, but is now also used on the new Malossi heads with curved fins (market launch 2021).
Total length: 51.7 mm
Ø stem: 4.45 mm
Ø undercut: 3.5 mm

The remaining parts required to complete the valve must be taken from the original valve (see accessories).
You can find complete racing kits, the matching pipes for the valve and other parts in the accessories section.
