Description
When you're pushing the YFZ450R to its limits, factory pistons become your weak link. The Wossner 8784DA is purpose-built to handle the demands of high-RPM riding while delivering measurable gains in reliability and throttle response. This is the piston kit serious YFZ450R owners choose when durability and performance matter equally.
Wossner engineered this kit with German precision using 4032 T6 forged aluminum—the same material trusted in professional racing applications. The permanent skirt coating reduces friction and piston rock, which translates to quieter operation and less wear on your cylinder walls. FEA optimization ensures every curve and dimension is calculated for maximum strength without unnecessary weight, while the T6 heat treatment guarantees consistent performance under sustained high-load conditions.
This is a complete replacement solution—no hunting for matching components.
