Description
The Wiseco Piston Kit PK1661 delivers the strength and thermal stability your DR-Z400 demands when you’re pushing peak RPMs and sustained high-load conditions. High-silicone forged construction minimizes expansion under heat, preserving ring seal integrity and reducing blowby—critical for maintaining compression and power output in a heavily modified or frequently ridden engine. This complete top-end kit eliminates the guesswork of sourcing compatible components individually.
