Installation information:

1. In general suitable on vehicles with the old version of Piaggio cylinder head (slider rocker arms). Mostly fitted till year of production 2014 (but also used longer). To mount the Malossi head the rocker arms, camshaft etc. of the OEM head have to be installed in the new head. Additional power increase by using Malossi camshaft M.5911962.
