The VERTEX Forged High Compression Top End Kit is engineered to enhance power and torque delivery across the entire rpm range. The core component, a forged piston, is manufactured from 2618 aluminum to ensure superior strength and durability. To further optimize performance and longevity, the piston undergoes a T-5 hardening and tempering heat treatment cycle. Additionally, the piston skirt features a high-tech Molybdenum Disulfide coating, which facilitates faster break-in times and increases overall piston life.
This comprehensive top end assembly includes the piston, OEM replacement rings, pins, circlips, and top end gaskets. Depending on the specific application, the kit also incorporates either a wrist pin bearing or a cam chain. By combining forged 2618 aluminum construction with precise heat treatment and advanced surface coatings, this kit provides a robust solution for riders seeking improved high-compression performance and extended component durability.
