Review WISECO Wiesco Piston fits RM80 1991–2001

The Wisesco 408P4 91-01 RM80 piston is a high-performance replacement part designed specifically for Honda RM80 motorcycles manufactured between 1991 and 2000. This piston is an excellent upgrade for riders seeking improved engine performance and reliability.

The Wisesco 408P4 piston is made from a forged aluminum alloy, ensuring superior strength and durability compared to its cast counterparts. The forged construction also allows for a more precise fit in the cylinder bore, reducing the likelihood of engine blowby and minimizing the potential for piston slap.

This piston features a compression height of 32.5mm and a total height of 66.0mm, which is suitable for most high-performance applications. The piston crown is designed with a dish shape that enhances the combustion process, increasing power output and improving overall engine efficiency.

These rings are made from high-quality materials that provide excellent sealing and longevity. The compression ring is designed to maximize combustion efficiency, while the oil control ring minimizes oil consumption and ensures reliable engine performance.

The piston skirt is designed with a flat, wide profile that provides excellent support to the connecting rod and reduces the potential for piston side-loading. The piston pin is made from high-strength steel and is precision-machined to ensure a perfect fit with the piston and connecting rod.

The Wisesco 408P4 91-01 RM80 piston is an excellent choice for riders who demand the best performance from their motorcycle. Its forged construction, high-quality ring package, and precision-machined components ensure superior strength, reliability, and power output. Whether you're racing or just riding for fun, this piston will help you get the most out of your Honda RM80.
