Reinforced crankshaft MAZZUCCHELLI Racing long stroke 44mm piston pin Ø12 PIAGGIO CIAO reed valve housings

For even more performance, here is the 44mm long stroke crankshaft from MAZZUCCHELLI for Ø12mm piston pin. Equipped with solid masses for more pre-compression, a revised and corrected connecting rod with reinforced crankpin placed on anti-friction shims and silver cage, quality balancing (this can be seen with the 4 side weights).


From the top of the range, this vilo will be installed on crankcases with valves, not to be forgotten given its long stroke 44mm, a shim under the cylinder in order to adjust the cylinder height with the stroke (a small shim of 0.5mm is enough so a good thick base gasket is sufficient). Fits on PIAGGIO CIAO BRAVO, BOSS, GRILLO, SI & SUPERBRAVO and other models but with engine casings with intake valves. Delivered with its needle cage. Resistant to 16,000 revolutions per minute!
