POLIN CYLINDER KIT FOR RACE

Cylinders, light alloy cast, to offer the best performance even at the highest working temperatures.They better dissipate the heat. They do not show mechanical and structural collapses.Specific bore according to the different models.Cylinder liner with nickel-siliceous coating. It better resists to wear and abrasion. It improves the piston sliding.Performing distribution diagramPiston, gravity cast in light alloy with high silicon contentHead combustion chamber with specific squish to eliminate detonations.
