cylinder head MALOSSI Maxi 4V H2O for Piaggio 125-300cc 4-stroke LC

Malossi 4-valve cylinder head for a 15–25% performance increase. Great for water-cooled 4-stroke 125, 180, 200, 250 and 300cc Piaggio engines (Leader and Quasar). On 125-200cc engines, larger cylinder kits and 4-valve pistons are required; on 250 and 300cc engines, no modifications are required. Made from cast aluminium alloy, hardened and sand blasted. Designed to the finest tolerances. Inlets worked to 25mm and outlets to 22.2mm. Cylinder head pre-assembled and ready to install.
Installation information:
1. On 125cc-200cc engines, only suitable in combination with Malossi cylinder kits.
2. On 250cc-300cc engines in combination with the OEM cylinder, the OEM piston needs small modifications. (Instructions included.)
3. Generally suitable for vehicles with the old version of the Piaggio cylinder head (slider rocker arms). Mostly fitted until the 2014 production year (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.
4. On newer vehicles with the newer version of the Piaggio cylinder head, which uses roller rocker arms (mostly from 2014 onward), the OEM rocker arms, camshaft etc. cannot be used in the Malossi cylinder head. An additional valve train conversion kit needs to be installed. Please use KIT.PI.39397 for 125-200cc engines (requires camshaft M.5911962) or KIT.PI.39402 for 250-300cc engines (requires camshaft PI-8759585). (Applies only to Gilera Runner 125 ST, Piaggio Beverly 125 10-, Beverly 300 10-, Piaggio X-Evo, X 10, Vespa GTS 125-300, GTV 300.)
