The Story
The Wossner 8105DC piston kit is a high-performance forged piston designed for the Honda CR85 series. With a 47.52mm bore and 47.47mm piston diameter, this +0.02 oversize piston enhances durability and thermal efficiency in two-stroke engine configurations. Engineered with an elliptical profile, it provides balanced load distribution and prevents piston collapse under thermal stress. This German-made piston kit is ideal for maintaining factory specifications while ensuring robust engine performance.
