Description
The Wossner 8156DA piston kit is engineered to restore or exceed your CR250R’s original performance capabilities while delivering the durability needed for sustained high-RPM operation. Factory pistons wear, lose compression, and create excess noise—this German-made kit eliminates those issues with precision-forged construction and a friction-reducing skirt coating. Whether you’re prepping for competition or refreshing a cherished two-stroke, this complete kit delivers the reliability and efficiency that serious riders demand.
What makes this kit stand out is the engineering behind it. Wossner developed the 8156DA using Finite Element Analysis to optimize ring sealing, minimize piston rock, and maintain consistent performance across the powerband. The 4032 T6 forged aluminum alloy construction combined with permanent skirt coating means lower friction, quieter operation, and longer service life—critical advantages when you’re pushing your engine to its limits.
