Description
The Yamaha RZ 350’s two-stroke engine demands a piston that can handle aggressive tuning and sustained high RPM operation without compromising reliability. Wiseco’s forged high-silicon aluminum construction delivers the strength needed for racing applications while the E-coating protects against detonation and micro-welding—common failure points in modified engines. This is a complete piston kit with rings, wrist pins, and circlips, so you have everything needed for a proper rebuild.
Wiseco’s design philosophy prioritizes bore sealing and compression retention through minimal exterior machining, which translates to better power delivery and more consistent performance across heat cycles. Whether you’re preparing for track competition or maximizing your street bike’s potential, this piston offers the durability and service intervals that justify its cost over standard OEM replacements.
