The Namura Piston Kit (B) Series is engineered with advanced technology for superior performance and durability. Featuring MOS2 (Teflon/Molybdenum) coated skirts, this piston reduces friction, increases heat transfer, and helps eliminate cold seizures. The machined smooth heads reflect combustion heat and reduce carbon buildup, enhancing horsepower and fuel economy by up to 6%. Anodized domes provide increased heat resistance and durability, while the hypereutectic casting process delivers excellent wear resistance and the ability to withstand higher cylinder temperatures. This kit includes an individually wrapped piston, OEM quality rings, a wrist pin, and cir-clips. Perfect for Yamaha YZ125 and YZ125X models.
