The piston's main body is made of a high-strength alloy material. This lightweight yet robust construction allows the engine to operate efficiently while withstanding the rigors of snowmobiling. Furthermore, it is nitride-treated to enhance surrender, reducing the risk of scuffing and ensuring a perfect seal with the cylinder wall.
The piston crown features a Pyrofee ring pack design, consisting of a compression ring, oil control ring, and skirt. These rings work in harmony to improve compression and seal piston-to-cylinder contact effectively, ensuring minimal blow-by gas escapes. In addition, the oil control ring assists in maintaining proper engine oil levels, maintaining engine lubrication and preventing premature wear.
The piston also has a bevel-edged, full-dished design. This innovative construction promotes proper piston to skirt interface and reduces the risk of piston slap. The full-dish design also ensures better engine efficiency by optimizing the combustion chamber shape for more optimal mixing and fuel combustion.
Lastly, this piston boasts a precision-made gudgeon pin. This vital component, made from high-strength material, ensures seamless connection between the piston and the connecting rod. The precise fitment and design enable the engine to operate smoothly, quietly, and efficiently, minimizing parasitic losses and increasing overall performance.
