Crankshaft Polini Racing HPC -AM6

Description

This is the latest crank from Polini for Minarelli AM6 engines. It features a full mass made from one solid block of material as oppose to its processor that had the nylon inserts. This boosts primary conpression giving a noticeable power gain. The connecting rod has also been re designed to be much stronger and cope with extreme running conditions. This is a crank designed for serious tuners and is designed to cope with 15000 + RPM and is therefore suitable for high end big bore kits
