The VERTEX Cast Replica Top End Kit is engineered for riders seeking a balance of weight reduction and structural integrity, utilizing gravity cast aluminum alloy with 18% silicone content. This specific alloy composition produces an extremely light yet strong piston, while the inclusion of new T-box forgings and DLC coated wrist pins ensures enhanced strength and performance. To optimize durability and reduce friction, all piston skirts feature a high-tech Molybdenum Disulfide coating, which facilitates faster break-in times and extends overall piston life.
Designed as factory-supplied replacements for KTM 2-stroke applications, these replica pistons are heat treated with a T-5 hardening and tempering cycle to ensure consistent material properties. The kit provides a comprehensive top end solution, including OEM replacement rings, pins, circlips, top end gaskets, and applicable wrist pin bearings or cam chains. By maintaining strict adherence to original equipment standards, this assembly delivers reliable performance across the entire rpm range without compromising the mechanical precision required for high-stress engine environments.
