Review WISECO PISTON Pistons 0.5mm Over 64.50mm #k130 Yamaha Rd400/rd350 fits RD400 RD350

Introducing the WiseCo K130 pistons, an excellent upgrade for your Yamaha RD400 or RD350 motorcycle. These pistons are specifically engineered to deliver enhanced performance and reliability, making them an ideal choice for enthusiasts seeking to optimize their two-wheelers.

Measuring 64.50mm in bore diameter with a compression height of 51.5mm, these pistons offer a 0.5mm overbore, which increases the engine's displacement and power output. The piston's crown is designed with a high compressional height and a dish shape to improve combustion efficiency and increase power.

The WiseCo K130 pistons are manufactured using a high-quality aluminum alloy, ensuring they are lightweight yet robust. They feature a precision-machined surface finish, which minimizes friction, reduces heat, and ensures a perfect fit in the cylinder bore. The piston rings are made of a high-performance material that ensures efficient sealing and reduces piston-to-cylinder wall contact, resulting in reduced wear and longer engine life.

The piston's design also includes a floating pin, which allows the piston to move more freely in the cylinder bore, reducing friction and improving engine smoothness. Additionally, the piston skirt is reinforced with ribbing, which adds rigidity and prevents deformation under high engine loads.

The WiseCo K130 pistons are a direct replacement for the stock pistons, making installation straightforward. They come with new piston rings, piston pin, and clips, ensuring a complete and hassle-free installation. Furthermore, the pistons are carefully balanced to ensure optimal engine performance and longevity.

Upgrading to the WiseCo K130 pistons is an investment in the performance and longevity of your Yamaha RD400 or RD350 motorcycle. These pistons offer increased power, improved engine smoothness, and enhanced reliability, making them an excellent choice for riders seeking to extract the maximum potential from their classic bikes.
