When dealing with the deep overhaul of a powertrain, accuracy is the only parameter that matters. The Athena engine gasket and fender series sets the standard of excellence for non-compromising. This all-in-one package is designed to offer total engine sealing system regeneration, ensuring that each mechanical coupling returns to work with, if not higher, the tolerances and reliability intended by the manufacturer.*Why choose the complete Athena kit**
Choosing this engine gasket set means investing in the longevity of your vehicle. Unlike partial kits, this series includes every single item needed to close the base and heat assembly. The main advantage is the integration of fenders, components that are often overlooked but vital to maintain proper internal pressure and prevent air infiltration or lubricant leakage that could compromise carburetion or lubrication of bench bearings. By purchasing this solution, you will not need to find the head gasket or valve fenders separately, as everything is already perfectly calibrated inside the package.*Advanced technology and materials**
Athena thermal seals and sealing components are the result of decades of R&D in collaboration with the most prestigious racing teams. Production employs the highest quality materials such as:
● High temperature resistant rubber-metal sheets.
● Technopolymers with silicone inserts for dynamic sealing.
● Carbon and special fibers to withstand extreme combustion pressures.
● Laser cutting and calibration for a millimeter match to the original crankcases.
Each element undergoes non-stick surface treatments and precision finishes that facilitate assembly and ensure clean separation during future maintenance.*Athena Signed Excellence**
Since 1973, Athena has been a world leader in endothermic engine parts. The strength of the brand lies in the ability to analyze the criticalities of original components and improve them. Through rigorous testing on test benches and race fields, Athena produces emery kits that often outperform the production of production parts, offering superior thermal and mechanical resistance essential for those who practice motocross or enduro at intensive levels.*Installation Tips and Warnings**
Replacing a complete set of gaskets and fenders is an operation that requires technical expertise.
● *Mounting Difficulty**: High. Assembly must be performed by specialized personnel, strictly following the instructions of the motorcycle manufacturer and using the clamping torques indicated in the workshop manual.
● *Warnings**: Make sure the crankcase surfaces are perfectly clean and free of residue from old seals before installation. Do not use additional silicone sealants unless expressly required by the manual, to avoid obstructing oil passages.*Why buy it on Crosshop**
