41 mm cast iron racing cylinder with Latin American temperament and 57 cc for your Puch M50, MS50, VS50, DS50, VZ50 small motorcycle.
The timing cam of the tuning cylinder was deliberately kept low, which results in particularly good torque in the lower engine speed range.
Thanks to the large sealing surface, no more pouring is required to close the slot on the housing compared to many other cylinder kits.
Compared to the Sombrero racing kit for Puch Velux X30 models, this version has a thinner cylinder neck so that it fits into the corresponding EX50 engine cases.
