Cylinder Malossi Sport 50cc Minarelli vertical

With the Sport 50cc version, Malossi offers a grey cast cylinder for daily use.
At low revs, it is somewhat less powerful than the Polini Sport cylinder, but it surpasses it by about 800 RPM, which gives it a slightly higher maximum power.
In these thermal groups, the characteristic high durability of cast iron is combined with Malossi's almost obsessive quality standards, one of the very few companies to demand the utmost even from this type of thermal group.
From this perspective, extremely strict selections are introduced for the coupling between cylinder and piston, rigorously maintained within the maximum tolerance band of 20 microns.
