Athena Standard Bore Cylinder Kit - 78mm, 250cc

This Athena Standard Bore Cylinder Kit is engineered for optimal performance and durability. Designed as a direct replacement, this kit ensures your engine runs as smoothly and reliably as it did when new. Athena has invested over a decade in developing aftermarket cylinder replacement parts, focusing on enhanced production and performance through continuous innovation.

All Athena cylinders are meticulously engineered in Italy by their expert R&D Department, utilizing advanced internal knowledge and state-of-the-art design and testing tools. The cylinders are coated with Motor-Nikasil, a proprietary nickel-silicon coating developed by Athena. This coating provides exceptional smoothness and superior wear resistance, contributing to the longevity of the component.

Athena's cylinder kits and their individual parts are globally recognized for their outstanding performance, exceptional durability, and unwavering reliability. The Standard Bore cylinder kit offers the same performance characteristics as original spare parts, providing extreme reliability and optimal smoothness. This is achieved through the use of a lightweight aluminum cylinder, a barrel featuring the advanced nickel-silicon coating, and a specially designed piston engineered to minimize friction.

This comprehensive kit includes a high-quality aluminum cylinder with a standard bore, a complete piston assembly with piston pin and rings, and all the necessary gaskets for a straightforward installation. Every component within this kit has been developed to withstand extreme temperatures, pressures, and stresses. Athena technicians have rigorously validated these components through demanding bench and track testing.
