Wossner pistons are renowned in the automotive industry for their high-performance and durability, and the 8156d100 piston, specifically designed for the Honda CR250R 2-stroke motorcycle from the years 1984-1985, is no exception. This piston is engineered to deliver enhanced power, increased reliability, and extended engine life.
The 94mm bore size of this piston is made from a proprietary alloy chosen for its exceptional strength and ability to withstand the high temperatures and pressure associated with high-performance 2-stroke engines. The piston crown is specifically shaped to provide optimal combustion efficiency and power output, which translates to improved engine performance and increased horsepower.
The piston skirt is designed with Wossner's patented "BP plus" coating. This coating provides enhanced piston-ring seal, reducing friction and ensuring efficient compression and power transfer. This results in higher engine efficiency, reduced wear, and extended engine life.
The piston's design also includes an optimized pin bore, precision machined crown, and a small denominator ring land. These features ensure a proper fit and alignment of the piston, ensuring proper ring land engagement, reducing the chance of ring flutter, and reducing the possibility of engine damage from ring-related issues.
Another important feature of this Wossner piston is its thin piston wall design. The thin wall reduces the weight of the piston without compromising its strength, contributing to a quicker response and improved engine performance.
