Malossi Racing 73ccm-12mm- Piaggio Bravo, Boxer, Superbravo, Boss, Grillo, SI

Description

Malossi cast iron thermal units, the first and simplest step to modifying your motorcycl’s engine, are the best choice for continued use of the exhaust system of an approved series or type.
For these thermal units, the elevated feature of durability of cast iron is combined with the almost manically high quality standards of Malossi, one of the few companies to demand the most from even this class of thermal units. Into this is inserted the most rigid selections for the joining of the cylinder and the piston, strictly maintained within a range of 20 microns maximum of tolerance.
The cylinder kit provides an increase in performance in terms of power and torque due to its new cast iron cylinder. The technical aspects of the bore and the exhaust fitting have been kept the same, but its complete redesign has led to the complete replacement of the port mapping, which now allows optimal coupling not only with our crankcases, but even with the original ones. Assembly of the cylinder kit on original crankcases requires only the boring of the cylinder liner hole.
