Cylinder kit POLINI Corsa cast iron Ø47 pin Ø12 Minarelli vertical
Article information
New Polini cylinder kits for Yamaha Minarelli engines.
Polini Motori presents the new range of kits for Minarelli engines mod. CY, MY, CW with Ø 12mm piston pin.
The cast iron cylinder with 6 transfers is machined with tools that grant high quality products, with sliding walls with controlled roughness for a better cylinder-piston sliding. The exhaust diagrams and the transfers have been designed to work in line both with the Polini Original and Scooter Team mufflers.
The piston is made of special alloy with a high siliceous percentage with the aim to grant the maximum resistance to high temperatures.
The piston rings are made of spheroidal cast iron and are highly resistant to wear.
The head is made of special aluminum light alloy with high coefficient of heat exchange. The combustion chamber has been completely redesigned for a high compression ratio with high turbulence.
Polini cylinders kits for Yamaha Minarelli engines must be installed together with the crankshafts with connecting rods for Ø12mm piston pins.
