Each piston in this kit is crafted using high-quality forged aluminum alloy. The forging process ensures a strong and consistent piston structure, resulting in superior strength and resistance to engine stress. The piston crowns are designed with an optimized dish profile to provide excellent combustion efficiency and power output.
The Namura MN/S349 Piston Kit also includes piston rings made from precision-machined chrome steel. These rings are designed to ensure a proper seal between the piston and the cylinder wall, preventing oil leaks and combustion gases from escaping. The rings are also properly grooved and sized to ensure a proper fit in the cylinder bore.
The piston pin is made from high-strength steel and is precision-machined to ensure a perfect fit in the piston. The piston pin retaining clip is made from heat-resistant steel and is designed to securely hold the piston pin in place, even under high engine temperatures.
The skirt of the piston is designed with a parallel-lip shape, which helps to reduce piston side-force and friction, resulting in reduced engine wear and improved efficiency. The piston skirt is also coated with a low-friction, high-heat resistant coating to further reduce friction and wear.
The Namura MN/S349 Piston Kit is designed to be a direct replacement for the OEM pistons on the Yamaha YFM700 Raptor engine. The pistons are precisely machined to ensure a perfect fit in the cylinder bore, and the piston rings are installed with the proper clearances to ensure proper engine operation.
In conclusion, the Namura MN/S349 Piston Kit is an excellent upgrade for your Yamaha YFM700 Raptor engine.
