MAZZUCHELLI: Big crankshaft at a low price. MAZZUCHELLI has put a long stroke full circle crankshaft on the market for all GILERA/PIAGGIO 2T Maxi pilots.

High compression full circle crankshaft with 2mm more stroke (54mm).

SIP-TIPP: As the crankwebs have a diameter of 93mm, this crankshaft is only suitable for the new crankcases which are originally equipped with a Ø92mm crankshaft. Unfortunately this cannot be pinned down to year of construction or chassis number.

The longer stroke needs to be compensated by means of a base gasket or by modifying the cylinder head. Although the crankshaft comes without an instruction manual, it demands a certain degree of expertise to be mounted correctly.
