ATHENA Standard Bore Cylinder Kit Ø 95 mm, 450 cc - P400485100015 (Includes Piston)
For over a decade, Athena has dedicated significant resources to enhance the production and performance of aftermarket cylinder replacement parts.
All cylinders are meticulously engineered in Italy by Athena's R&D Department, leveraging extensive internal expertise and state-of-the-art tools for design and testing. These cylinders feature motor-nickisil coating, a proprietary nickel-silicon blend developed by Athena to ensure smoothness and superior wear resistance.
Athena's cylinder kits and components enjoy global recognition for their exceptional performance, longevity, and dependability.
The Standard Bore cylinder kit from Athena delivers equivalent performance to original spare parts, offering exceptional reliability and smooth operation. This is achieved through a combination of a lightweight aluminium cylinder, a barrel coated with nickel-silicon, and a piston engineered to minimize friction.
The kit comprises a high-quality aluminium cylinder with standard bore, a complete piston including piston pin and rings, and all necessary gaskets.
Each component is designed to withstand high temperatures, pressures, and stresses, undergoing rigorous bench and road tests by Athena technicians for validation.
Installation of this cylinder kit requires no modifications to the engine crankcase.
CAUTION! Ensure compliance with specific national regulations regarding the use of Athena products. Athena bears no responsibility for improper usage.
