The piston pin is made of precision-machined chrome molybdenum steel, ensuring a strong and reliable connection between the piston and connecting rod. The pin is also tapered, allowing for easy installation and removal.

The piston skirt is designed with a full-skirted, flat-top profile, which helps reduce piston side-force and increases piston stability. This results in better engine performance and improved engine life.

The piston kit is also compatible with OEM Honda connecting rods, making it a simple and cost-effective upgrade option for those looking to improve the performance of their CR480 or CR500. The piston kit is also backed by WiseCo's 1-year warranty, giving customers peace of mind and confidence in their purchase.
