<p><br>
The Ø68,5 cylinder with 60mm stroke, allows the displacement to increase to<br>
221cc; made of aluminum allows a better heat dissipation by lowering the<br>
operating temperature in the most difficult conditions.</p>
<p><br>
The cylinder has been renewed by replacing the muffler mounting, obtained<br>
from castings, with a single piece steel manifold fixed with 4 screws to the<br>
cylinder.</p>
<p><br>
The piston has been entirely redesigned with large passages on its skirt, to<br>
facilitate the feeding of the transfer ducts.<br>
The shape of the dome has been optimized to increase resistance and<br>
cooling.</p>
<p><br>
The head with increased finning over the entire surface allows the<br>
achievement to the maximum heat dispersion. The dome is entirely machined<br>
and coupled to a copper seal to improve performance and optimize cooling;<br>
the centering pins of the cylinder allow having a constant squish area over the<br>
entire diameter of the cylinder.</p>
